Community dwelling Korean adults (N = 40) coping with the stress of severe mental illness were randomly assigned to a six-week differentiation furthering intervention (experimental) or a directed problem-solving treatment program (control) and administered pre- and posttreatment measures including the Morey Personality Assessment Screener (PAS) and Group Embedded Figures Test (GEFT). As predicted, the experimental group showed greater improvement on 6 out of 10 mental health subscales (PAS) and on the GEFT than the controls. For the entire sample, differentiation gainers showed more improvement on three PAS subscales compared with the no change or loss in differentiation groups. A three-month follow-up showed greater attendance at mental health appointments for the experimental group over controls and for total sample differentiation gainers over nongainers. Implications are discussed of this empirically tested model of a community intervention to facilitate coping with stress and enhancing competence., (Copyright 2001 John Wiley & Sons, Inc.)

This paper presents a comparison for two samples (college and noncollege) of older, urban African-American adolescents of correlations between two measures of exposure to community violence (victim and witness) and four types of psychological trauma symptoms (anger, anxiety, depression, and dissociation). The central issue is the generalizability of previous findings about these relationships obtained from beginning college students of traditional age. The two samples did not differ in the magnitude of either the zero-order correlations or the multiple correlations between the two types of exposure to community violence and the four types of symptoms of trauma. The conclusion is that findings regarding the relationship of exposure to community violence with psychological symptoms of trauma obtained from college students may tentatively be generalized to older adolescents who are not in college.

Congenital bilateral absence of the vas deferens (CBAVD) occurs in approximately 1.3% of infertile males and is thought to be, in most cases, a primarily genital form of cystic fibrosis (CF). Fourteen males with CBAVD considering microsurgical sperm aspiration from the epididymis (MESA) and in vitro fertilization were seen for genetic counseling and screening for CF. To retrospectively evaluate these patients' perceptions of the counseling and screening information, we conducted structured telephone interviews to assess their recall of information about CF and its impact on their health concerns and reproductive plans. We found that, as the health implications of CF are abstract and not as important to patients as the diagnosis of CBAVD itself, patients tend to view their CF status primarily in terms of their reproductive potential. Retrospective analysis afforded us an opportunity to identify the psychosocial issues of most concern to this unique patient population.

We report on a fetus with 47,XX,+15 chromosome abnormality detected on chorionic villus sampling (CVS). The pregnancy was terminated at 15.5 weeks of gestation and chromosome analysis done on amniocytes and fetal tissues showed a karyotype 46,XX/47,XX,+15. Autopsy showed multiple abnormalities. Short-arm polymorphisms of the three number 15 chromosomes were highly informative in the delineation of parental origin and the stage of meiotic error. Using fluorescent in situ hybridization (FISH) with D15Z1 and a chromosome 15 painting probe, in addition to DA/DAPI and G-banding, we were able to show that the trisomic conceptus was derived through maternal meiosis I error. The trisomic state was then partially corrected by the loss of one of the two maternal 15s resulting in mosaicism without uniparental disomy (UPD). Striking differences in the proportion of trisomic cells in kidneys, blood, intestine, and skin, and lower proportions of trisomic cells in transformed and frozen than in fresh tissues, illustrate the continuing cell selection in this fetus in favour of the normal cell line. Trisomy 15 conceptions are usually aborted spontaneously in the first trimester of pregnancy. The longer survival of this fetus is most probably the result of a chromosome 15 loss from the trisomic zygote. To the best of our knowledge, the presence of this lethal trisomy has been reported in only five live-born infants, and in five fetuses including the present case, it was detected prenatally and the pregnancies were terminated.

This study compares anxiety levels in women undergoing prenatal testing by means of chorionic villus sampling versus genetic amniocentesis. Chorionic villus sampling can be performed earlier in a pregnancy (8 to 12 weeks' gestation) but has a higher risk of miscarriage. Randomized to undergo chorionic villus sampling or genetic amniocentesis as part of a trial examining the safety and accuracy of these procedures, the women were studied at four time periods: time 1, before prenatal testing (9 to 12 weeks' gestation); time 2, after the chorionic villus sampling results were received (13 weeks); time 3, before the genetic amniocentesis results were known (18 weeks), and time 4, after all results were known (22 weeks). Although they were still at risk for miscarriage, members of the chorionic villus sampling group showed a sharp drop in anxiety levels immediately after receiving their results. The genetic amniocentesis group remained anxious until the last test time. In summary, prenatal testing by means of chorionic villus sampling resulted in earlier and sustained anxiety reduction.

Assay of serum creatine kinase activity is useful in the detection of carriers of the X-linked gene for Duchenne muscular dystrophy (DMD). For genetic counselling this assay has been used in conjunction with pedigree analysis to improve estimates of the risk that a female relative of a DMD patient is a carrier. To measure the impact of the program, follow-up information was obtained from women who had received genetic counselling for DMD. Their responses showed that the risk of producing an affected son had been a major factor in their attitude toward family planning, and their reproductive performance correlated inversely with their genetic risk. The decision by the majority of proven carriers to prevent the birth of further male offspring was reflected in a recent decline in the frequency of a known family history of DMD among newly ascertained cases.
