Objective
Our earlier study on complementary and alternative medicine (CAM) methods showed that acupuncture, homeopathy, and aromatherapy are available in most obstetrics departments in Germany but it did not evaluate the clinical indications for using CAM. The present study aimed to explore further the effectiveness of CAM use in obstetrics.Study design
We sent all departments of obstetrics in North Rhine-Westphalia a questionnaire designed to delineate their use of acupuncture, homeopathy, and aromatherapy during childbirth. It sought details on who provided the CAM therapy (midwife or physician). We asked respondents to indicate on a five-point scale how reasonable or otherwise they would consider the provision of CAM in each of six common problem situations and to estimate for each the proportion of patients given the CAM treatment. Respondents were also asked about the rationale for offering CAM, quality assurance and side effects. Spearman's bivariate correlation, cross-tabulation and Pearson's χ2 test were used for statistical analysis.Results
About 73.4% (138/187) of the departments responded. Acupuncture and homoeopathy were most widely used. Although obstetricians are responsible for patient care, decisions to provide CAM were largely taken by midwives, and the midwives’ belief in the methods’ effectiveness and patient demand were the principle motivating factors. Rates of CAM use in the six problem scenarios evaluated were directly related to practitioners’ perceptions of the methods’ therapeutic effectiveness.Conclusions
CAM methods were widely offered despite the lack of evidence of effectiveness or information on adverse consequences. In Germany, including CAM in the mandatory national quality assurance measures and perinatal surveys would provide valuable information; CAM use elsewhere merits further study. 相似文献92.
The prototypic mineralocorticoid receptor agonist aldosterone influences neurogenesis in the dentate gyrus of the adrenalectomized rat 总被引:1,自引:0,他引:1
Glucocorticoid receptor activation inhibits granule cell proliferation in the hippocampus, but little is known about the role of mineralocorticoid receptors in this process. Here we administered aldosterone to adrenalectomized (ADX) rats, and monitored neurogenesis by BrdU immunohistochemistry. ADX significantly increased the number of BrdU-positive cells and aldosterone replacement further augmented BrdU-positivity. Our results indicate that aldosterone, most probably acting through mineralocorticoid receptors, may positively influence the proliferation and survival of newly-generated granule cells. 相似文献

PURPOSE: To assess thermal effects of Q-switched Er:YAG laser trephination to corneal epithelium and superficial stroma using different mask types and materials for experimental penetrating keratoplasty. METHODS: Laser trephination was performed in 20 freshly-enucleated porcine eyes (repetition rate 5 Hz, pulse energy 65 mJ, spot size 0.7 mm). We used flat, open-metal and ceramic masks for donor and recipient trephination placed directly onto the corneal surface. Main outcome measures as assessed by light microscopy after PAS staining of 8-microm paraffin sections included: extension of tissue thermal damage at the cut edge in the superficial and basal epithelial layers, the basement membrane and subepithelial stroma, and depth and width of epithelial/stromal involvement in the area of the donor mask contact. RESULTS: The thermal damage in the superficial epithelium was more pronounced in donor (mean extension 61.6 +/- 15.6 microm) than in recipient (29.4 +/- 24.9 microm, p= 0.05) trephination. In donor trephination, thermal damage zone of the superficial epithelial layer was significantly smaller with ceramic than with metal masks (21.0 +/- 23.0 versus 61.6 +/- 15.6 microm, p= 0.014). In contrast, differences at basal epithelial layer (p= 0.44), basement membrane (p= 0.79), and subepithelial stroma (p= 0.2) were not statistically significant. Superficial donor involvement of the cornea adjacent to the paracentral donor mask contact zone was seen neither with ceramic nor with metal masks. CONCLUSION: Superficial corneal alterations adjacent to the mask-cornea contact zone may be minimized by using the Er:YAG laser in a Q-switched mode. Ceramic masks, in contrast to metal masks, further reduce superficial thermal alterations at the cut edge. 相似文献

BACKGROUND: Bilateral stromal corneal opacifications are a differential diagnostical challenge to identify associated systemic diseases. CASE-REPORT: A 47-year old civil engineer (height 167 cm) with bilateral stromal corneal clouding presented with visual loss for the last 27 years: VA 20/100 OD and 20/50 OS (following penetrating keratoplasty OS). The cornea showed milky-whitish, cloudy, diffuse stromal deposits without a separate lipoid arc. The posterior segment showed tapetoretinal degeneration. Scotopic ERG was decreased. A suspicious stiffness of interphalangeal joints on both hands was observed. There was an aortic and mitral insufficiency grade I. Serum levels of LDL, HDL and triglycerides were normal. The biomicroscopical diagnosis of Scheie's syndrome (mucopolysaccharidosis I-S) was confirmed by a deficiency of alpha-L-iduronidase in leukocytes (0.02 nmol/min/mg protein, normal range: 0.3 - 1.5). CONCLUSION: The differential diagnosis of bilateral corneal stromal opacification includes in addition to the mucopolysaccharidoses HDL-deficiency diseases (LCAT deficiency, Tangier disease, Fish eye disease), Schnyder's crystalline stromal dystrophy, cystinosis, gout and mucolipidoses. MPS I-S may easily be detected by alpha-L-iduronidase deficiency in leukocytes and increased mucopolysaccharides in the urine. Furthermore, patients with MPS I-S need general medical care because of cardiovascular abnormalities, joint stiffness and myopathies. 相似文献

Angiostatic proteins and peptides 总被引:5,自引:0,他引:5

Angiogenesis, or the formation of new vasculature out of preexisting capillaries, is a sequence of events that is essential in the normal physiological processes of tissue growth and in a broad spectrum of pathologies. The diseases in which angiogenesis plays a key role are divided into diseases that are characterized by hypoxia/ ischemia and diseases that are dependent on neovascularization. The formerpathologies may benefit from therapeutic angiogenesis stimulation. This review concentrates on the different strategies to inhibit angiogenesis in diseases that are characterized by excessive angiogenesis, for example, cancer, arthritis, diabetic retinopathy, and inflammatory diseases. These diseases are dependent on the development of newvasculature, and hence, a large variety of different strategies to inhibit angiogenesis are underwayin laboratories throughout the world. At present, over250 angiogenesis inhibitors are described, and approximately half of them display activity in in vivo models. A large percentage of these molecules are natural, nonnatural, or synthetic so-called small molecules. Others are of protein origin, either endogenous or exogenous by nature. The authors highlight the current knowledge on the development of angiostatic proteins and peptides and their potential in the treatment of disease. 相似文献

OBJECTIVE: The aim of this study was to assess the use of circulating trophoblast cells in maternal peripheral blood for noninvasive prenatal diagnosis of numeric chromosomal aberrations. STUDY DESIGN: A combined procedure for immunocytochemical identification and deoxyribonucleic acid fluorescence in situ hybridization was used after a single enrichment step consisting of density gradient centrifugation. A specific HLA-G monoclonal antibody was used in combination with X and Y chromosome specific probes in deoxyribonucleic acid fluorescence in situ hybridization to confirm fetal identity of cells bearing HLA-G in the case of a male fetus. RESULTS: We detected fetal trophoblast cells expressing HLA-G in maternal blood starting at 9 weeks' gestation. In addition to fetal sex prediction with X and Y chromosome-specific probes, fetal aneuploidy was confirmed in peripheral blood from a pregnancy complicated by trisomy 21. CONCLUSION: Although the numbers of fetal cells were extremely low, the proof of concept was demonstrated. Early noninvasive prenatal screening for numeric chromosomal abnormalities with fetal trophoblast cells is feasible. 相似文献

PURPOSE: To introduce a method to correct phase errors (e.g., from B0 inhomogeneity) in tagging images, which may affect harmonic phase (HARP) evaluation. MATERIALS AND METHODS: The phase images corresponding to the negative and positive harmonic peaks in k-space are combined before HARP evaluation to eliminate any spurious phase. To validate in vivo, two complementary spatial modulation of magnetization (CSPAMM) data sets were collected for each volunteer and evaluated with conventional HARP, using either the positive or the negative harmonic peak, and with peak-combination HARP. RESULTS: Elimination of phase distortion by peak combination was observed in vitro and in vivo. Improved reproducibility of motion parameters was found with peak-combination HARP. CONCLUSION: With peak-combination HARP, reproducibility of contractile parameters is improved, and consequently, the number of subjects needed to detect statistically significant changes in contractile function can be reduced to one third compared to conventional HARP evaluation. 相似文献

The aim of the present study was to investigate the effect of long-term diet and very long chain n-3 fatty acids (VLC n-3) intervention on plasma coagulation factor VII (FVII), choline-containing phospholipids (PC) and triglycerides (TG), especially related to the R353Q polymorphism of the FVII gene. The present investigation included 219 subjects from the Diet and Omega-3 Intervention Trial on atherosclerosis (DOIT), a 2x2 factorial designed study in elderly men with long-standing hypercholesterolemia. The subjects were randomly allocated to receive placebo capsules (corn oil) (control), placebo capsules and dietary advice ("Mediterranean type" diet), VLC n-3 capsules, or VLC n-3 capsules and dietary advice combined. The R353Q genotype and the levels of FVIIc, FVIIag, FVIIa, PC, and TG at baseline and after 6 months were determined. Diet intervention was followed by a significant reduction of 5.1% in the levels of FVIIag and 2.4 mU/ml in FVIIa (95% CI -7.4, -2.9, and -3.8, -1.1, respectively) (both p<0.001) compared to the no diet group, independent of genotype. No effects of diet intervention on FVIIc, PC or TG were observed. After VLC n-3 supplementation the TG levels were significantly reduced compared to placebo (p=0.01), whereas all FVII levels and PC remained unchanged. Dietary advice towards a "Mediterranean type" diet, but not VLC n-3 supplementation, was shown to reduce the levels of FVIIag and FVIIa after 6 months, independent of genotype. The results indicate the dietary advice to be more favourable in reducing this risk factor for CVD as compared to specific VLC n-3 supplementation. 相似文献
