[Bacteriology and constitutional health--genomics and proteomics: concepts in medicine and concepts in health insurance in the past and future].

Future discussions on health issues on the individual or society level will be fundamentally linked to genetic dispositions. This genetic world will become reality in the same way the world of hygiene and bacteriology has become real for everyone. Approaches of molecular medicine for public health issues have not yet been created so far. The secret dreams of molecular eugenics must be made public and critically discussed. Up to now only a few monogenetically recessive hereditary diseases can be detected by screening. This kind of screening should be carefully considered. However, for the sciences, for medicine and thus for the physicians in practice, for health care sciences as well as for public health care, new tasks will emerge from genetics and molecular medicine. In individual as well as public health these new tasks will at first mainly turn in on the sphere of diagnosis and specific screening as well as health education and consultation. With regard to the considerable social implications the public health care sector should be aware of the coming issues of molecular medicine in time.

Conception and the concept of harm.

In recent years, science and the courts have created new options whereby prospective parents can avoid the birth of a diseased or defective child. We can ascertain the likelihood that certain genetic diseases will be transmitted; we can detect a number of fetal abnormalities in utero; we have legal permission to abort for any reason, including fetal abnormality. With these new options come new questions concerning our moral obligations toward our prospective offspring. An important conceptual question concerns whether such congenital diseases and defects constitute harms to the children who bear them. In this essay I shall examine the prevailing analysis of harm, the "Otherwise-Condition" approach, which denies that we can predicate harm of such abnormalities. I will show first that this analysis is inadequate even to account for certain very ordinary, clear cases of harm. It thus is suspect regardless of its stance on congenital anomalies. Second, it sets up an ill-considered connection between harm and causation - a connection which renders its harm ascriptions slippery, arbitrary. Finally, this analysis cannot be squared with certain of our deeply entrenched moral intuitions. By thus rebutting this most influential definition of harm, I will have opened the door to the possibility of ascribing harm for congenital disease and defect.

Follicular development and early luteal function of conception and non-conceptional cycles after human in-vitro fertilization: endocrine correlates.

Two-hundred patients, half of whom had on-going pregnancies, were examined in terms of follicular growth, urinary oestrogen and LH output, oocytes recovered and embryos replaced. The two groups were identical in all parameters measured except that urinary LH output was significantly higher (P less than 0.01) in non-pregnant patients on the two days prior to HCG administration. During the early to mid-luteal phase, plasma progesterone concentrations were related to the number of follicles aspirated at oocyte recovery, but the overall pattern of secretion was similar in both groups. It is concluded that monitoring urinary LH output, a non-invasive technique, may be of great value for assessing oocyte quality and predicting the outcome of in-vitro fertilization and embryo replacement.

Comparison of pyruvate uptake by embryos derived from conception and non-conception natural cycles.

The uptake of pyruvate by human embryos derived from natural cycles in the first 24 h following fertilization was examined. Since only one egg was obtained and therefore only one embryo transferred to the woman, it was possible to relate pyruvate consumption by a particular embryo to the outcome of that cycle (pregnancy or no pregnancy). The results showed that embryos have a wide range of pyruvate uptake values (2-53 pmol/embryo/h) but that this variation was reduced significantly to an intermediate range of values in those embryos that were able to implant (10-30 pmol/embryo/h). An association was found between embryo morphology and pyruvate consumption. Morphologically good embryos were more likely to implant if they demonstrated an intermediate pyruvate uptake. However, poor embryos did not implant even if they had a pyruvate uptake of 10-30 pmol/embryo/h. No relationship was found between the type of infertility and pyruvate consumption of individual embryos. It is suggested that the ability of an embryo to implant is multifactorial and that both morphology and pyruvate uptake may be factors.

Simple extraction and enzyme immunoassays for estrogen and progesterone metabolites in the feces of Macaca fascicularis during non-conceptive and conceptive ovarian cycles.

A simple method for extracting ovarian steroids from feces is presented, together with enzyme immunoassay systems for measuring estrogen and progesterone metabolites. Small amounts of feces were combined in a 1:10 proportion with a modified phosphate buffer, shaken for 24 h, centrifuged, and decanted; the supernatant was directly measured for estrogen and progesterone metabolites by enzyme immunoassays. Serum estradiol and progesterone profiles were compared to urinary and fecal profiles in the same animals to determine the degree to which each reflected the ovarian events detectable in serum. The correlation coefficients for the relationship between serum, urinary, and fecal hormones for individual animal cycles were found to be statistically significant in every case but one, where the relationship between serum estradiol and urinary estrone conjugates was not significant. Urinary and fecal measurements were used to determine whether estrogen and progesterone metabolism and excretion varied within and between animals. Variation in unconjugated estrogen and progesterone metabolites was observed in the follicular phase, the luteal phase, and early pregnancy.

New concepts in superovulation strategies for assisted conception treatments.

Controlled ovarian stimulation for in-vitro fertilization treatment using preparations that contain follicle-stimulating hormone has been routinely performed since the 1980s. The early preparations were urinary human menopausal gonadotrophins, containing follicle-stimulating hormone and luteinizing hormone. In the early 1990s, highly purified follicle-stimulating hormone preparations were introduced because of a desire to provide drugs for subcutaneous administration with a lower risk of allergic reactions. Intensive research resulted in the discovery of recombinant follicle-stimulating hormone, which is more potent that the highly purified follicle-stimulating hormone, resulting in significantly higher clinical pregnancy rates. The two recombinant follicle-stimulating hormone preparations available appear to be equally effective and provide comparable results. Gonadotrophin-releasing hormone antagonists, which have recently been introduced, appear to be effective in preventing a premature rise in luteinizing hormone during ovarian stimulation for in-vitro fertilization, as well as improved response to lower doses of gonadotrophins. It is envisaged that the availability of recombinant gonadotrophins and gonadotrophin-releasing hormone antagonists will ultimately lead to shorter, cheaper and safer treatments, using reduced dosages.

The Ponseti method for treatment of congenital club foot.

PURPOSE OF REVIEW: This review of the Ponseti technique for the treatment of congenital club foot covers a topic of recently renewed interest. Pediatric orthopedists and parents have become increasingly enthusiastic about the success of this technique, which has been practiced continuously at the University of Iowa since 1948 but only recently become widely utilized. RECENT FINDINGS: Current literature has emphasized the reproducibility of these excellent results among multiple centers throughout the world. In addition, the role of the Internet, and accessibility of medical information have been central elements in the development of this phenomenon. SUMMARY: The current research should convince physicians that all children should be managed by the Ponseti technique at the outset. This research should also reassure physicians and parents that the overwhelming majority of children with club feet can be successfully managed, without the need for major reconstructive surgery.
