Abstract
Auditory integration training and a control treatment were provided for 16 children with autism in a crossover experimental design. Measures, blind to treatment order, included parent and teacher ratings of behavior, direct observational recordings, IQ, language, and social/adaptive tests. Significant differences tended to show that the control condition was superior on parent-rated measures of hyperactivity and on direct observational measures of ear-occlusion. No differences were detected on teacher-rated measures. Children's IQs and language comprehension did not increase, but adaptive/social behavior scores and expressive language quotients decreased. The majority of parents (56%) were unable to report in retrospect when their child had received auditory integration training. No individual child was identified as benefiting clinically or educationally from the treatment.

Abstract
The skills of a total population of children with severe intellectual disability and/or autism from Camberwell, South London, UK, and the initial follow-up data, taken when the subjects were adolescents and young adults (Shah 1986), are described in the present study. Changes in skills over time are presented within the categories of communication, self-care, and educational and cognitive skills, as assessed by the Handicaps, Behaviours and Skills schedule. The results indicated that skills had improved in many areas between times 1 and 2, but that this improvement was more noticeable for the children who had been youngest at time 1. The implications of these results and predictions for a further follow-up study are discussed.

Abstract
Bothrops ammodytoides, the smallest representative of this genus, is found only in Argentina. Venom was extracted from thirty adult specimens (35-70 cm in length, 90-300 g in weight) captured in the Province of Buenos Aires and kept in captivity. Venom yield was 3-30 mg. SDS-PAGE showed strong bands at 14.0; 23-25; 45; 54 and 63 kDa and weak bands at 17.0; 30.0; 40.0 and 85.0 kDa. Toxic activities were: LD50 (intravenous, mice) 0.5+/-0.2 microg/g; minimal procoagulant dose on human plasma (MPD-P) 35+/-2 mg/l; and minimal defibrinogenating dose (MDD, mice) 6-12 microg. Hemorrhagic and/or necrotic activities appear to play a major role in lethality; minimal hemorrhagic dose (MHD, mice) is 10+/-2 microg/g and minimal necrotizing dose (MND, mice) is 38+/-5 microg. The LD50, MPD-P and MND are among the lowest in venoms from Bothrops species found in Argentina. B. ammodytoides venom exhibited high proteolytic and phospholipase A2 activities. Most of the B. ammodytoides venom components cross-react with Bivalent Bothropic antivenom (Instituto Nacional de Producción de Biológicos ANLIS Dr. G. Malbrin, against B. alternatus and B. neuwiedii venoms). One ml of antivenom neutralizes 1.2 mg of B. ammodytoides venom.

Abstract
PURPOSE Finasteride, an oral type 2, 5alpha-reductase inhibitor, is used in 1 mg. daily doses for the treatment of male pattern hair loss. A dose of 5 mg. finasteride daily reduces ejaculate volume by approximately 25%, and reduces prostate volume by approximately 20% and serum prostate specific antigen (PSA) by approximately 50% in men with benign prostatic hyperplasia. To our knowledge no data exist on the effect of 1 mg. finasteride daily on ejaculate volume or other semen parameters, or on the prostate in young men. Therefore, we studied the potential effect and reversibility of effect of 1 mg. finasteride daily on spermatogenesis, semen production, the prostate and serum PSA in young men. MATERIALS AND METHODS In this double-blind, placebo controlled multicenter study 181 men 19 to 41 years old were randomized to receive 1 mg. finasteride or placebo for 48 weeks followed by a 60-week off-drug period. Of the 181 men 79 were included in a subset for the collection and analysis of sequential semen samples. RESULTS There were no significant effects of 1 mg. finasteride on sperm concentration, total sperm per ejaculate, sperm motility or morphology. Ejaculate volume in subjects on finasteride decreased 0.3 ml. (-11%) compared to a decrease of 0.2 ml. (-8%) for placebo, with a median between treatment group difference of -0.03 ml. (1%, 90% confidence interval -10.4 to 13.1, p = 0.915). There were significant but small decreases in prostate volume (-2.6%) and serum PSA (-0.2 ng./ml.) in the finasteride group, which reversed on discontinuation of the drug. CONCLUSIONS Treatment with 1 mg. finasteride daily for 48 weeks did not affect spermatogenesis or semen production in young men. The effects of 1 mg. finasteride daily on prostate volume and serum PSA in young men without benign prostatic hyperplasia were small and reversible on discontinuation of the drug.

Abstract
DSM-IV states that Asperger Disorder may be distinguished from Autistic Disorder by a lack of a delay in early language development. The aim of this study was to establish whether the presence or absence of early language delay would predict autistic symptomatology in children diagnosed with a PDD/autism spectrum disorder. Forty-six language-delayed and 62 normal language onset individuals (M age 11 years) were compared on ICD-10 research criteria and DSM-IV criteria, receptive language, and developmental history variables. Retrospective data were also obtained to determine whether language onset predicted autism symptomatology when young (< 6 years). We found that early language delay predicts more autistic symptomatology when young, but not at an older age. Early language delay is also associated with developmental motor milestone delays and lower receptive language abilities. The results question the use of early language delay as a valid discriminating variable between PDD subgroups.

Abstract
Comprehensive data on the developmental history and current behaviours of a large sample of high-functioning individuals with diagnoses of autism, Asperger's syndrome, or other related disorder were collected via parent interviews. This provided the basis for a taxonomic analysis to search for subgroups. Most participants also completed theory of mind tasks. Three clusters or subgroups were obtained; these differed on theory of mind performance and on verbal abilities. Although subgroups were identified which bore some relationship to clinical differentiation of autistic, Asperger syndrome, and Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS) cases, the nature of the differences between them appeared strongly related to ability variables. Examination of the kinds of behaviours that differentiated the groups suggested that a spectrum of autistic disorders on which children differ primarily in term of degrees of social and cognitive impairments could explain the findings.

Abstract
OBJECTIVES The teen birth rate is commonly used in comparing regional variation in teen pregnancies, but local teen birth rates are not always available. In this study the percentage of all births that are to teens was evaluated for its utility as a surrogate for the teen birth rate. METHODS Rank correlation and sensitivity and specificity analyses were used. RESULTS The Spearman rank correlations between percentage of teen births (PTB) and teen birth rate (TBR) were .995, .906, and .841 for the 3 age groups suggesting that it may be reasonable to employ PTB to prioritize zip codes. Zip codes with upper quartile levels of percentages of teen births identified zip codes with upper quartile levels of TBR with a sensitivity of 83.8%, 68.8%, and 65%; a false-positive rate of 2.1%, 8.6%, and 10%; and a positive predictive value of 89.3%, 67.6%, and 67.5% for the age groups 10 through 14, 15 through 17, and 18 through 19 years. CONCLUSIONS The percentage of births to teens is a useful surrogate for teen birth rate in California, especially among younger teenagers.

Abstract
Spermatogenesis is a complex process requiring the coordinate expression of a number of testis-specific genes. One of these, Pdha-2, codes for the murine spermatogenesis-specific isoform of the E1a subunit of the pyruvate dehydrogenase complex. To begin to delineate the mechanisms regulating its expression in vivo, we have generated transgenic mice lines carrying Pdha-2 promoter deletion constructs. Here we report that transgenic mice harboring a construct containing only 187 bp of promoter and upstream sequences (core promoter) is sufficient for directing the testis-specific expression of a chloramphenicol acetyltransferase (CAT) reporter gene. Like the endogenous Pdha-2, the CAT gene is expressed in testis in a stage-specific manner. Our studies also show a correlation between CpG methylation within the core promoter and its capacity to regulate transcription. In NIH 3T3 cell lines stably transfected with the Pdha-2 core promoter-CAT construct, high levels of CAT reporter expression are observed, whereas the endogenous Pdha-2 gene is repressed. In these cells, the CpG dinucleotides residing within the transfected promoter are hypomethylated whereas those residing in the endogenous promoter are methylated. Furthermore, promoter activity can be abated by the in vitro methylation of its CpG dinucleotides. DNase I footprint analysis indicates that at least one site for the methylation-mediated repression may occur through the ATF/cyclic AMP response element binding element located within the core promoter. Mutations within this element reduces activity to approximately 50% of the wild-type promoter activity. These results suggest that tissue-specific gene expression may be modulated by other mechanisms in addition to specific transcription factor availability and cooperativity. We propose that methylation may be a mechanism by which repression of the testis-specific Pdha-2 gene is established in somatic tissue.

Abstract
1. The binding characteristics and mRNA levels for renal adenosine A1 receptors were investigated in normal rats and rats with acute renal failure (ARF) induced by either glycerol or HgCl2. 2. Saturation isotherms determined from the binding of [3H]-1,3-dipropyl-8-cyclopentylxanthine ([3H]-DPCPX), a selective adenosine A1 antagonist, to renal membranes of untreated rats gave values of 0.62 nM for the equilibrium dissociation constant (Kd) and 19.9 fmol mg-1 protein for the density of binding sites (Bmax). No saturable binding was observed with [3H]-2-(p-(carboxylethyl)-phenylethylamino)-5'-N-ethylcar box amido adenosine ([3H]-CGS 21680), a selective adenosine A2a agonist. 3. By contrast to time-matched controls, renal membranes obtained from rats 16 and 48 h following the induction of ARF with glycerol, showed statistically significant increases (2-4 fold) in both Bmax and Kd for the binding of [3H]-DPCPX. No significant changes in the binding characteristics of [3H]-DPCPX were noted with membranes from rats 48 h following the production of ARF with HgCl2. 4. Adenosine A1 receptor mRNA levels were significantly elevated 0.5, 16 and 48 h following induction of ARF with glycerol, whilst no change was noted in mRNA levels for beta-actin at the same time points. No statistically significant changes in adenosine A1 receptor or beta-actin mRNA levels were noted 48 h after the induction of ARF with HgCl2. 5. This study indicates that glycerol-induced ARF in the rat is associated with an increase in renal adenosine A1 receptor density which appears to result from increased transcription of the gene for this receptor. An increase in adenosine A1 receptor density in renal resistance vessels may explain, at least in part, the enhanced renal vasoconstrictor response to adenosine in glycerol-induced ARF that was noted in a previous study.

Abstract
OBJECTIVE To determine what clinical symptoms clinicians have been using to distinguish between Asperger's disorder (AsD) and autistic disorder (AD). METHOD Parents of children and adolescents with high-functioning AD (n = 48) and AsD (n = 69) were given a structured interview based on DSM-III-R and ICD-10 diagnostic criteria. Information regarding early and current symptom presentation and family, developmental, and verbal mental age information were collected. Logistic regression analyses were conducted to determine which variables best predicted clinician's diagnosis. RESULTS A number of clinical variables predicted diagnosis. Delayed language onset was the only variable of the family and developmental variables that predicted diagnosis. The AsD group was also significantly higher than the AD group in verbal mental age. CONCLUSION Clinicians appear to be diagnosing AsD and AD on the basis of published research and case study accounts. The findings question whether DSM-IV and ICD-10 criteria adequately describe the AsD individual, particularly in the communication domain.

Abstract
OBJECTIVE To determine whether known maternal risk factors for low birth weight directly contribute to infant mortality among very low birth weight infants. DESIGN Retrospective population-based, case-control study. SETTING Four hospitals in the Oakland, California, area: one community, two private, one health maintenance organization. PARTICIPANTS All live-born singleton very low birth weight ( < 1500 g) infants born to Oakland residents over a 3-year period. Cases were infants who died before their first birthday, identified by computerized linkage of birth and death certificates. For each case, a surviving control was selected to match for birth weight, sex, and race. Forty matched pairs were identified in total. OUTCOME MEASURES Prevalence of maternal risk factors among cases versus controls. RESULTS After controlling for other factors known to influence either birth weight or infant mortality, maternal cocaine use (odds ratio [OR] = 5.43), prior infant death (OR = 27.14), and planned pregnancy (OR = 6.33) were significantly associated with the survival of very low birth weight infants. CONCLUSIONS Some maternal risk factors for low birth weight confer a survival advantage to very low birth weight infants. Our data reveal that maternal cocaine use is independently associated with survival among this subset of infants. Prior research supports the observed relationship as well as the scientific plausibility of a cocaine-mediated survival advantage among premature infants. Our study also showed both planned pregnancy and prior infant death to be independently associated with infant survival among this subset of infants, suggesting that maternal behaviors may play a role in determining birth weight-specific mortality. These data should be systematically evaluated to better define their relationship to infant mortality.

Abstract
Injection drug use is a major risk factor for human immunodeficiency virus (HIV) infection and drug treatment is widely recognized as a core component of the public health effort to limit the spread of HIV. The assumption is frequently made that lack of immediate access to treatment is a significant barrier to the success of this effort. However, little empirical data exist to support this belief. We conducted a trial of no-cost outpatient drug-free treatment made available on demand to a cohort of out-of-treatment injection drug users (IDUs) in Portland, Oregon, through a coupon program. Of 824 IDUs, 272 (33%) expressed an interest in treatment, 225 (27%) accepted a coupon, 66 (8%) redeemed a coupon, and 9 (1%) remained in treatment for 6 months. These numbers indicate that simply enhancing access is not adequate. Additional strategies to increase motivation to enter and remain in treatment are needed if drug treatment is to play an important role in reducing the spread of HIV among injection drug users, their sexual partners, and their infants.

Abstract
Fifty-six sexually-abused girls and their nonoffending female caretakers from primarily low-income. African American families were comprehensively assessed in order to determine factors related to child symptomatology and self-blame. Girls whose overall relationships with their caretakers were somewhat negative exhibited more behavioral difficulties. Girls with disruptions in their relationship with a primary caretaker and who felt powerless as a result of the abuse were rated as functioning less well overall by clinicians. Child age, general attributional style, and caretaker blame of the child were related to child self-blame. Clinical implications of these findings include identification of clients at high risk for negative sequelae and development of interventions targeted at specific clinical issues.

Abstract
Although autism can occur in conjunction with a range of other conditions, the association with Down syndrome is generally considered to be relatively rare. Four young boys with Down syndrome are described who were also autistic. All children clearly fulfilled the diagnostic criteria for autism required by the ICD-10 or DSM-III-R, but in each case the parents had faced considerable difficulties in obtaining this diagnosis. Instead, the children's problems had been attributed to their cognitive delays, despite the fact that their behaviour and general progress differed from other children with Down syndrome in many important aspects. The implications, for both families and children, of the failure to diagnose autism when it co-occurs with other conditions such as Down syndrome are discussed. Some speculations about possible pathological associations are also presented.

Abstract
A useful system to evaluate the angiogenic activity of hormones and growth factors is the chorioallantoic membrane (CAM) of chick embryos. The present studies examined the angiogenic activity of chicken anterior pituitary glands and both fibroblast growth factor (FGF) and growth hormone (GH). Grafts of anterior pituitary gland evoked an angiogenic response on the CAM which was lost if the adenohypophyseal tissue was first boiled. The magnitude of the angiogenic response to anterior pituitary glands increased with the age of the donor (from a minimum 15 days of embryonic development to a maximum between 2 and 6 weeks old). In view of the similarity of the profile of the angiogenic response and the reported changes in GH secretion, the angiogenic activity of GH was then examined. Considerable angiogenic responses were observed with GH; there being increases (P < 0.05) in number of new blood vessels on the CAM of chick embryos on which native chicken GH or native bovine GH or recombinant bovine GH were added. These data support GH having an angiogenic action.

Abstract
Renal vascular reactivity was studied in rats with acute renal failure (ARF) to investigate whether changes in sensitivity to the renal haemodynamic effects of adenosine can explain why adenosine plays a significant role in some but not all forms of ARF. Experiments involved rats with glycerol-induced ARF in which adenosine antagonists have been shown previously to have beneficial effects and rats with HgCl2-induced ARF which was not ameliorated by treatment with the selective A1 antagonist 8-cyclopentyl-1,3-dipropylxanthine (0.1 mg/kg). Close renal arterial injections of adenosine (0.1-10 micrograms) or noradrenaline (0.003-0.1 microgram) produced falls in renal blood flow in rats with HgCl2-induced ARF which were not statistically different from controls. Adenosine evoked falls in renal blood flow in rats with glycerol-induced ARF which were significantly greater 16 and 48 h, but not 30 min after glycerol injection. The enhanced responsiveness to adenosine's renal constrictor effects was most pronounced 48 h following glycerol injection when, for example, a dose of 10 micrograms produced a fall of 60 +/- (SEM) 5% (n = 8) in renal blood flow in comparison to a fall of 27 +/- 5% (n = 8) in controls. By contrast to the renal vascular response to adenosine, the falls in renal blood flow induced by noradrenaline in rats 48 h following glycerol injection were not statistically different from the decreases in renal blood flow recorded in control animals.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
While recent studies indicate that injection drug users (IDUs) can change their behavior to reduce injection risk of HIV, it remains unclear which users are most likely to change and which mediating variables are most amenable to intervention. We report a study in which a cohort of high-risk IDUs was followed over time to determine which variables were associated with reduced injection risk of HIV. Of 317 IDUs who at baseline had shared a dirty needle in the previous 30 days, 234 (74%) were followed for 6 months. Of these, 107 (46%) reported reduced or eliminated injection risk between the baseline and follow-up interviews, 82 (35%) by not injecting and 25 (11%) by not sharing syringes. Those who attended self-help meetings between the two interviews were almost twice as likely to report reduced or eliminated risk as those who did not attend (OR = 1.92; p = 0.04). The findings suggest that, at least, IDUs in self-help groups comprise a population amenable to HIV interventions and, at most, that self-help groups may play an important role in reducing the risk of HIV in out-of-treatment populations.

Abstract
This article describes how a continuing care ward attempted to deal with an increase in levels of violence towards staff and looks at how changes that were taking place on the ward may have contributed to a reduction in this problem. Possible lessons for the future management of this group of patients and reduction of violence are drawn from the discussion.
