Idiopathic precocious puberty versus puberty in adopted children; auxological response to gonadotrophin-releasing hormone agonist treatment and final height.
(17/279)
OBJECTIVE: The objective of this study was to evaluate the characteristics of puberty and response to gonadotrophin-releasing hormone (GnRH) agonist treatment in adopted children compared with children with idiopathic precocious puberty (IPP). METHODS: We studied 17 girls with central IPP (group A) and 11 girls adopted from Asia and Central and South America (group B) with respect to auxological data at presentation of puberty and response to GnRH agonist treatment. RESULTS: In adopted girls, age at onset of puberty was later and duration of treatment was shorter. At the start of treatment, height-standard deviation score (H-SDS) was +1.67 s.d. in group A. In group B, H-SDS was comparably increased (+0.04 s.d.) assuming that the mean H-SDS in their native country is lower than the mean on the Dutch curve. During treatment, H-SDS decreased in both groups. Group A reached a final height (FH) of 166.2 cm (-0.3 s.d.) and group B of 156.1 cm (-1.9 s.d.). Predicted adult height (PAH) at the start of treatment underestimated FH in group A and overestimated FH in group B. At the end of treatment, PAH overestimated FH in both groups. The SDS for weight was above the mean in both groups at the start of treatment and increased even more during treatment. The age of occurrence of menses after treatment was stopped was the same in both groups (12.7 and 12.8 Years respectively). CONCLUSION: Despite the difference in timing of puberty between girls with IPP and adopted girls with early puberty, their response to treatment was similar in many aspects. (+info)
Releasing pre-adoption birth records: a survey of Oregon adoptees.
(18/279)
OBJECTIVE: In June 2000, Oregon implemented a citizen-initiated ballot measure that grants adult adoptees access to their birth records, which contain their birth parents' identifying information. Because other states are considering similar policy changes, the authors explored whether Oregon's new law is meeting the information needs of adoptees. METHODS: Birth records were abstracted for a 9% (221/2,529) random sample of adoptees who obtained their records from June 20, 2000, to July 20, 2000, to describe the population and the information they obtained. Telephone interviews documented their motivations, expectations, and whether they considered the birth record useful. RESULTS: The mean age of the adoptees was 41 years, 64% were female, and 97% were white. Virtually all received information about their birth mother; however, only one-third received information about their birth father. Of the 221 sampled, 123 (59%) participated in the telephone survey, 12 were ineligible, 84 could not be reached, and 2 refused. The most common motivations for requesting records were to find birth parents (29%) and to obtain medical information (29%). Twenty-nine percent received less information than they expected, with many expecting, but not receiving, birth father information. Thirty-three (47%) of the 70 adoptees who tried to find their birth mother were successful. The records were considered "very" useful by 52% of respondents, "somewhat" or "a little" useful by 42%, and "not at all" useful by 6%. CONCLUSIONS: The results indicate that many adoptees received less information than they expected, and many did not meet their goals of finding birth parents or obtaining medical information. Nonetheless, the majority considered their birth records useful and important. (+info)
Releasing pre-adoption birth records: the impact of Oregon's experience on its vital records department.
(19/279)
OBJECTIVE: In November 1998, Oregon voters passed Ballot Measure 58, which allowed Oregon adoptees > or = 21 years of age access to their original birth records, which are sealed at adoption. The objective of this study was to evaluate the impact of the measure on the Oregon Health Division (since renamed Oregon Health Services) by assessing procedures used and resources needed after implementation of Measure 58. METHODS: Vital records employees were interviewed about processing, storage, and archive retrieval procedures for pre-adoption birth records before, during, and after the implementation of Measure 58 and the effect on their usual workload. Personnel time, space, and fiscal resources used to process requests for pre-adoption records were also calculated. RESULTS: The Oregon Health Division began to receive requests from adoptees immediately following the passage of Measure 58 in November 1998, but due to legal challenges, they could not be processed until May 31, 2000. From June 2, 2000, through October 20, 2000, 12 staff members and two supervisors issued more than 4,700 pre-adoption birth records while also processing their normal workload, which averages more than 135,400 vital record orders annually. Due to the need for retrieval from archives, requests for pre-adoption birth records were estimated to take 75 hours to process vs. 2-3 minutes for standard requests. Each batch of approximately 75 pre-adoption birth records required approximately 12.5 person-hours from vital records staff and 3-4 person-hours from archive personnel; in addition, supervisors spent time responding to incomplete orders, informing the public and the media, and responding to concerns of adoptees, birth parents, and adoptive parents. Fewer than 1% of requests went unfilled. CONCLUSIONS: Implementation of Measure 58 utilized substantial resources of the Oregon Health Division. States contemplating similar legislation should consider increasing personnel and resources, preparing for intense public and media interest, and reorganizing the storage of adoptees' original birth records so they are easily retrieved.

Brain imaging of language plasticity in adopted adults: can a second language replace the first?
(20/279)
Do the neural circuits that subserve language acquisition lose plasticity as they become tuned to the maternal language? We tested adult subjects born in Korea and adopted by French families in childhood; they have become fluent in their second language and report no conscious recollection of their native language. In behavioral tests assessing their memory for Korean, we found that they do not perform better than a control group of native French subjects who have never been exposed to Korean. We also used event-related functional magnetic resonance imaging to monitor cortical activations while the Korean adoptees and native French listened to sentences spoken in Korean, French and other, unknown, foreign languages. The adopted subjects did not show any specific activations to Korean stimuli relative to unknown languages. The areas activated more by French stimuli than by foreign stimuli were similar in the Korean adoptees and in the French native subjects, but with relatively larger extents of activation in the latter group. We discuss these data in light of the critical period hypothesis for language acquisition. (+info)
Measles outbreak among internationally adopted children arriving in the United States, February-March 2001.
(21/279)
On February 16, 2001, the Texas Department of Health was notified about a child aged 10 months adopted from orphanage A in China who was taken to a Texas hospital with fever, conjunctivitis, coryza, Koplik spots, and a maculopapular rash. Measles was confirmed by serologic testing. Public health authorities in Texas notified CDC, which then collaborated with health officials in other states to contact other recently adopted children from China and their adoptive families. This report summarizes the results of multistate contact investigations that identified 14 U.S. measles cases and outlines measures taken in the United States and China to control and prevent measles transmission.

Clinical variables and genetic loading for schizophrenia: analysis of published Danish adoption study data.
(22/279)
Schizophrenia shows considerable clinical variation, but the relationship between clinical variables and degree of genetic loading for schizophrenia is unclear. We investigated this by analyzing published data from the adoption study of Kety et al. (1994) in Denmark. We sought to determine which clinical variables in proband adoptees with chronic schizophrenia predicted risk of schizophrenia in their biological relatives, using logistic regression analysis. We found that risk of chronic schizophrenia in relatives was predicted by the presence of pervasive negative symptoms (odds ratio [OR] = 9.44, 95% confidence interval [CI] = 1.98-45.01) and absence of pervasive positive symptoms (OR = 0.09, 95% CI = 0.01-0.78) in probands. Pervasive negative symptoms were defined by the presence of all of the symptoms: social withdrawal, autistic behavior, poverty of thought/speech, and flat affect. Pervasive positive symptoms were defined by the presence of all of the symptoms: suspiciousness/ideas of reference, delusions, auditory hallucinations, and other hallucinations. These clinical variables may be useful for refining phenotypic definitions of schizophrenia in molecular genetic studies. (+info)
Adoption as an offspring strategy to reduce ectoparasite exposure.
(23/279)
Adoption occurs frequently in colonial species where both the cost of parasitism and the opportunity for dependent young to find a foster family are typically high. Because ectoparasites show highly aggregated distributions among colony members, we tested two central predictions of the novel hypothesis that adoption is driven by selection on young to reduce ectoparasite load: first, that nest-based ectoparasites cause offspring to seek adoption, and second, that an individual's parasite load will be reduced after it has been adopted. In agreement with these predictions, experimentally infested Alpine swift Apus melba offspring sought adoption significantly more often and at an earlier stage than young kept free of ectoparasitic louse-flies. Second, the parasite load of experimentally infested young was reduced after adoption via a redistribution of ectoparasites among the foster family members. Our findings emphasize what we believe to be a novel role for parasites in the evolution of adoption and, by extension, in the emergence of social interactions. (+info)
What is new in adoption.
(24/279)
Adoptions arranged through adoption agencies are on the increase because there are more agencies. The Citizens Committee on Adoption of Children in California has concluded that there are very few adoptable children under care in orphanages. Fifty per cent of physicians would prefer agency adoptions, but only 24 per cent actually refer both expectant mothers needing such services and couples wishing to adopt infants to such agencies. The program in this field of social welfare should be child-centered and physicians should seek and give cooperation to such agencies. (+info)
