Issues of social policy and ethics in gene technology.

Technical developments in the last ten years have made possible mapping and sequencing of the entire human genome, along with the possibility of treating genetic disorders by manipulating DNA. A variety of issues regarding potential uses and abuses of these technologies have become apparent. They relate to both genetic screening and gene therapy. Problems facing individuals and their families mostly revolve around rights of self-determination and of confidentiality. Health care professionals will need to design optimal systems to provide genetic counseling and to protect confidentiality of DNA data bases. Society and social institutions will need to develop policies and laws that protect the privacy of individuals whose DNA is stored in data banks. Patenting of the results of gene research remains controversial internationally. Moreover, there is concern in many quarters about society's potential abuse of gene technology for eugenic purposes. Gene therapy is now a reality. There is little disagreement on the use of gene therapy to treat genetic diseases in individuals by somatic cell therapy. There is much controversy, however, over the use of germ-line cell therapy. Gene technology has contributed to the growth among a small group of influential people of the Post-Modern Movement, which is strongly antiscience and antitechnology. This movement may pose a long-term threat to future technological advances and should not be ignored. There is much outside of the laboratory that scientists, particularly molecular biologists, can do to assure a secure place for science and technology in our culture.

The pneumococcus and some men who came to Yale: the Dorothy M. Horstmann Lecture.

Yale has been fortunate indeed to have had Dorothy Horstmann as a member of its faculty for all but one of the last 50 years. It has had also the wisdom to take cognizance of her value as an individual and of her contributions to biomedical science and human welfare on two occasions in recent years. Her studies of poliomyelitis, hepatitis, and rubella, executed with perceptiveness, rigor and modesty, have benefited countless numbers; and for her many achievements all are in her debt. I am beholden to her colleagues for this opportunity to pay tribute to a wise and gracious friend. In casting about for a subject befitting this occasion, the thought occurred that it might be of interest to examine the contributions of some former and present members of Yale's faculty to the subject of a group of infections still endemic in all human societies, namely those caused by Streptococcus pneumoniae or the pneumococcus. The list is doubtless not exhaustive but includes such notables as Winternitz, Blake, Paul, Trask, Eaton, and Beeson of former days, as well as reflecting ongoing investigations today by Eugene Shapiro and his colleagues. In reviewing some of this earlier work, it will be my endeavor to place it in the context of contemporary understanding. In the interest of some semblance of order, the material will be examined in topical rather than in chronological order, dealing with bacteriologic and immunologic, pathogenetic, therapeutic, and prophylactic considerations in that sequence.

[Abortion in Japan].

In Japan, the artificial abortion is a penal offence; only in the presence of certain conditions it is authorized under the provision of the Eugenic Protection Law which was promulgated in 1948. According to the law, the artificial abortion is restricted to the period, in which the fetus is not viable outside of the uterus. This period is prescribed by notification from the Ministry of Public Welfare; up to now it has been shortened twice (1976, 1991). Due to the introduction of economic reasons in the list of conditions and the simplification of the procedure the artificial abortion in Japan was virtually liberalized. Prosecution for illegal abortion is very rare in recent years. The number of reported artificial abortions decreases; in the about last 30 years it reduced by half. However, the increase in the number of abortions in women younger than 20 years of age is a problem. The abortion in teenagers is late compared with that in other age groups. Although the number of neonaticides does not seem to increase, the increase in the number of abortions in teenagers remains a serious problem in Japan.

[Congenital malformations: care or predict?].

Spectacular scientific and technological advances made in the last decade have had such a profound impact on biological and medical science that they have dramatically modified the citizen's behaviour concerning life events, especially congenital malformation. Prenatal diagnosis (PND) leads to do the diagnosis of almost all fetal internal and external malformations. The matter is, not only to care, but, first to know. The positive efficiency of PND is sometimes preparing the best cares and, of course, to recognize many severe anomalies postnatally diagnosed before PND time, and carrying wellknown 50% rate mortality by neo-natal surgery. Congenital diaphragmatic hernia is pointed out as a good example of it, and of hopes and disappointing in utero foetal surgery. New protocol of assessment of fetal renal function is an appreciated method to do prognosis of some fetal uropathies before late in utero drainage, for a short time waiting for necessary maturation of lungs allowing premature delivery. The possibility to do PND of small and benign malformation leads to ask for the question of utility of to know. In spite of the respect of quality of life, can we really allow this type of human selection to be made? The next knowledges of the human genoma map bring us into the predictive medicine. Using "compulsory" PND is a real risk to practice dangerously, a soft eugenism. PND must be, and remain an outstanding advance to provide better treatment.

Insurance and genetic testing: where are we now?

Basic research will spur development of genetic tests that are capable of presymptomatic prediction of disease, disability, and premature death in presently asymptomatic individuals. Concerns have been expressed about potential harms related to the use of genetic test results, especially loss of confidentiality, eugenics, and discrimination. Existing laws and administrative policies may not be sufficient to assure that genetic information is used fairly. To provide factual information and conceptual principles upon which sound social policy can be based, the Human Genome Initiative established an Ethical, Legal, and Social Issues Program. Among the first areas to be identified as a priority for study was insurance. This paper provides a review of life, health, and disability insurance systems, including basic principles, risk classification, and market and regulatory issues, and examines the potential impact of genetic information on the insurance industry.

[Uniparental disomy: a review of causes and clinical sequelae].

1) Uniparental disomy (UPD) results from the exceptional derivation of a pair of the offspring chromosome from one parent only and has been documented thus far for chromosomes 2, 4, 5, 6, 7, 11, 13, 14, 15, 20, 21, 22 both X's and the XY pair. Its consequences on the phenotype may result from three potentially harmful effects, namely isodisomy, interference with genomic imprinting and, occasionally the vestigial aneuploidy from which UPD may have originated. 2) In isodisomy, the uniparental pair is partially or entirely homozygous, through the duplication of a same chromosomal DNA template, thus bringing about an increased risk of recessive disorders. As a result, conditions such as cystic fibrosis, a type of osteogenesis imperfecta, thalassemia alpha or beta, retinoblastoma, rod monochromacy, etc., have now been reported. 3) Duplication of both homologues of a parental pair in a diploid genome is called heterodisomy. Both iso- and heterodisomy may also cause disruption of the genomic imprints normally modifying the differential expression of some maternal and paternal genes or gene sequences needed for eugenic growth and development, in the course of normal biparental inheritance. Such a disturbance can be one of the causes of congenital clinical entities as well defined as Angelman, Prader-Willi or Beckwith-Wiedemann syndromes and some new syndromes, for instance for UPD 7 mat, UPD 14 mat and, probably also 14 pat. 4) All in all, UPD can cause morbidity or lethality by altering imprinting processes, mimicking certain deletions or duplications, generating recessive disorders or prompting malignant tumor development. 5) In the clinical field, UPD occasionally upsets some mendelian tenets of traditional inheritance, and raises, the question of the evolutional role plaid by genomic imprinting (GI). An hypothetical opinion is that one of GI potential side effects is a biased intergenerational preferential display or skip of parental features. This could be so because some of the inherited genes or gene domains only gain maternal or paternal expression in the offspring, as a function of their parental imprint.

[100 years of conflict about schizophrenias].

A systematic concept of a homogeneous group of psychoses, which Eugen Bleuler subsequently termed "Schizophrenia", goes back to Emil Kraepelin initially, in fact it has not existed for more than 100 years. The dynamics inherent in its history show that it is advisable to make allowance for contemporary influences when arriving at conclusions on schizophrenia in our times. The article in question presents a brief review of the origins and the historic development of the concept of schizophrenia, and attempts to set the present-day "neo-kraepelian" re-assessment of schizophrenic disorders in a modifying historic context.

The corneal epithelium after optisol-GS storage.

The objective of this study was to evaluate the epithelium of human corneas stored in Optisol-GS (Chiron Intraoptics, Irvine, CA) for extended periods (2-34 days). Human corneas stored in Optisol-GS (n = 64) were obtained from the Georgia Eye Bank. Corneal epithelial viability was assessed by using the Calcein-AM (Molecular Probes, Inc., Eugene, OR) ethidium homodimer stain, a fluorescent assay used to distinguish live from dead cells. Scanning and transmission electron microscopy was used to evaluate epithelial ultrastructure. The results showed that corneas stored up to 6 days in Optisol-GS had minimal damage of the epithelium. Calcein-AM ethidium homodimer staining showed 20-25% epithelial damage. Corneas stored 7-10 days had a further increase in epithelial damage (30-35%). Corneas stored for 11-15 days had marked increases in epithelial damage (40-50%), and corneas stored 16-34 days showed significant epithelial damage (60-70%). The data show that corneas stored in Optisol-GS are able to maintain the epithelium up to 6 days. A gradual decrease in epithelial viability and loss of epithelial cells occurs in corneas stored 6-10 days. Corneas stored for > 10 days have a marked loss of epithelial cells with extensive epithelial damage.

[Knee problems from a medical history viewpoint].

Knee-joint problems have worried our medical ancestors time and again and made them search for unconventional solutions. Four small case studies are meant to give the reader an insight into the paleopathology and medical history of knee-joint diseases. A grotesquely deformed knee-joint of a young ladies' tailor from the hospital cemetery of Basle (1846) has been investigated paleopathologically and led to the diagnosis of a severe knee-joint tuberculosis. Based on the rediscovered written legacy of the Zurich country doctor Felix Heusser (1817-1875), his significance as an up to now underrated pioneer of knee-joint resection is illustrated. The example of the first knee-endoprosthesis invented by Themistocles Gluck (1853-1942) demonstrates how an ingenious idea can very seriously affect the career of a very promising physician. Another milestone in knee surgery, the invention of knee arthroscopy by the controversial Argovian surgeon, military commander and politician Eugen Bircher (1882-1956), deserves once more our attention.

[Therapeutic abortions: basis and ethical foundations].

For thirty years medical abortion is allowed by law. Since 1975 habits, medicine, society had tremendously changed. From a clinical study we research the different factors influencing medical abortion. We questioned foetus medical history, parents ability, medical staff, society and law about medical abortion. We were interested by ethical dilemma following severity assumption, quality of life and foetal evaluation. By the end we tried to separate medical abortion and eugenism and we suggested a practical course following ethical concerns.

[The importance of counseling in the context of prenatal diagnosis].

Counseling plays a central role of the utmost importance in the doctor-patient/client relationship in medical genetics. Historically, its development may be described as a paradigm shift from eugenics via preventive medicine to a more psychosocial understanding as a communication process, which aims at individually bearable, autonomous decisions. The widely accepted conception of non-directiveness in genetic counseling has implications for the rights of patients and clients as well as for the duties of those offering and performing genetic diagnosis and counseling. In the context of prenatal diagnosis, genetic counseling has its special role as a framework to prevent ethically unacceptable automatism and to safeguard the interests of the individual patient/client. In view of the marked lack of adequate counseling capacities, increasing the potential of prenatal genetic diagnosis requires the development of different, possibly new concepts for counseling in this area.

Cell cycle and apoptosis: possible roles of Gadd45 and MyD118 proteins inferred from their homology to ribosomal proteins.

The function and structure of many disease gene products are currently poorly understood, and the easiest way to proceed is to search databases for homologous proteins to infer function or structure from the closest database match. Bioinformatics provides a variety of methods that reach beyond the standard database searches with single query sequences. The identification of a large superfamily of ribosome-associated proteins by computer analysis enabled Eugene Koonin to infer functional information for Gadd45, which is part of a cell-cycle checkpoint pathway defective in ataxia-telangiectasia.

[Genetics and society: ethic and legal implications].

Medical genetics, recently individualised as a full medical specialty, evidences new problems issued from its natural and historical developments. Genetics counselling, prenatal and predictive diagnosis may be considered as a real progress when applied in the strictly medical and individual fields. When extended to the whole community to answer collective choices, these technologies can turn into eugenic and standardizing practices. Regarding the public health and the economic necessity it could be inviting to overpass the essential values on which are founded our humanity. In that context laws are required to defend the best use for human being several practices, but only after an ethical debate in which everyone should participate.

[Genetic diagnosis of the embryo before implantation].

The association of recent progress in two initially faraway fields, assisted reproductive technology and molecular biology, has made way for the preimplantation genetic diagnosis (PGD). For some people this new technique was, immediately, considered as an alternative to prenatal diagnosis for couples at risk of offspring affected with severe genetic diseases. This technique has the advantage of avoiding an eventual abortion and replacing it by an in vitro embryos preselection. For others PGD appeared, above all, as matter of new eugenic risk. In fact, these excessive hopes and fears have contributed to blurring the true current problems of PGD, technical difficulties and still limited reliability. While the French law has admitted the principle of PGD use, the measures for its application remain to be defined. But this legal authorization must recognize that this new technique will be, for a long time, at the stage of research, improvement and assessment.

Analysis of rabbit tear fluid using capillary electrophoresis with UV or laser-induced fluorescence detection.

In preliminary studies of the development of tear analysis methodology that may eventually be useful in the clinical setting, the authors evaluated various protocols for analyzing rabbit tears by capillary zone electrophoresis (CZE). Conditions included the use of a 50-mM monosodium phosphate buffer, pH 2.5, or a 400-mM sodium borate buffer, pH 8.9, both with ultraviolet (UV) detection, as well as a 50-mM borate buffer, pH 8.5, with laser-induced fluorescence (LIF) detection of ATTO-TAG CBQ (Molecular Probes, Inc., Eugene, OR, U.S.A.) derivatized tears. All CZE analyses were performed with a P/ACE System 2100 instrument equipped with System Gold software (Beckman Instruments, Fullerton, CA, U.S.A.), using a 50 microns x 57 cm (50 cm to the window) fused-silica capillary, at 25 degrees C, with constant voltage of 20 kV for UV detection and 11 kV for LIF detection. Tear samples were collected from normal rabbit eyes by means of 10-microL glass micropipets. The volume of each sample was approximately 2 microL. Analysis using the phosphate buffer with UV detection produced as many as 35 peaks in each sample, of which 11 peaks were readily discerned. This compared favorably with sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis, which produced 32 bands with silver staining and 11 quantifiable bands with Coomassie brilliant blue staining. Many of the tear protein components have yet to be identified. CZE analysis with the high-ionic-strength borate buffer with UV detection produced only four peaks, and the low-ionic-strength borate buffer with LIF detection produced only six peaks. CZE analysis was completed in less than 1 hr, compared with 7-8 hr for SDS-PAGE. In summary, CZE analysis of tear fluid is comparable to CZE analysis of other bodily fluids and shows great potential for use in clinical diagnosis as well as for enhancing our understanding of the cellular actions of tears on the front of the eye.

[Can we define the indications for oocyte donation?].

The outline of oocyte donation's indications is defined in France by the law of the 29 july 1994. A great number of situations do not pose any problem with regard to this principles: gonadal dysgenesis, premature ovarian failure, ovariectomy, castration following chimiotherapy or radiotherapy. However, others indications drive us progressively outside legal limits. What is the normal age of physiological menopause? Which threshold to justify oocyte donation for low responders? Is oocyte donation an alternative for other treatments failures? Ovocyte donation for genetic reason presents a risk of eugenic drift. Answering these questions is uneasy, though it is urgent for our patients to offer them a better uniformity.
