The present study concerns the impact of recalled parental rearing behaviour on both the intensity of the wish to have a child and on different motives to have a child. Until now there are no empirical studies as to this objective. Our study is based on a representative sample of 1509 persons aged 18 to 50 years. The statistical analyses were restricted to those subjects who lived in partnership and reported an actual wish to have a child (n = 331). The data were assessed by self-reporting scales: The Questionnaire of Recalled Parental Rearing Behaviour "Fragebogen zum erinnerten elterlichen Erziehungsverhalten, FEE", the Partnership Questionnaire "Partnerschaftsfragebogen, PFB", and the Leipzig Questionnaire of Motives to Have a Child "Leipziger Fragebogen zu Kinderwunschmotiven, LKM". A recalled parental rearing behaviour, which was characterized as having been rejective, overprotective and less emotionally warm was associated with such motives which do not promote the wish to have own children (fear of personal restrictions and a low degree of social support). Simultaneously, a negative parental rearing behaviour was correlated with a stronger desire for social recognition by an own child. The recalled maternal rearing behaviour was altogether stronger associated with motives to have a child than the paternal. On the other hand, no relevant associations could be found between the recalled parental rearing behaviour and the intensity of the wish to have a child. 相似文献

The basic principles dealing with euthanasia (1998) as expressed by the German Association of Doctors states that in advance written directives are of "substantial help for the doctor in his or her actions". This requires, however, wide proliferation of patient directives. Hence it was important to ascertain the prevalence of such directives in the German population, as well as the relationship to the wish for enlightenment in terminal illness and diseases in their final stages. This was accomplished in December 1998 using 2050 people obtained with the Random-Route-Procedure (1024 from the new German states, 1013 from the old German states). The sample was obtained from the opinion research institute USUMA with ages ranging between 14 - 92. The main results from this representative survey represent an important record of the status quo with respect to opinion shaping of patient autonomy. 16 % of this survey expressed the wish not to be fully enlightened in the case of a terminal illness or they wished for a clarification to be given to the family only. This result shows that part of the population still holds on to their right of no knowledge. 59.1 % expressed the wish for a complete and immediate enlightenment. The other 24.9 % desired a careful step-by-step presentation of information. The high percentage of those who desired information and enlightenment is in contradiction to the small 2.5 % of patients who have actually written advance directives. These empirical results are consistent with the clinical experience of many doctors and represents the decision of the "representational" doctors for the current ethical regulation of patient directives as an ideal idea. Since 71.9 % of those surveyed had never before thought about this issue conclusions are drawn regarding patient consultations. Gender and East/West differences are also shown. 相似文献

Serological tests are commonly employed to aid the diagnosis of Streptococcus pyogenes infections, particularly when non-suppurative sequelae are suspected. Conventional laboratory practice is to measure antibody levels to various combinations of the extracellular group A Streptococcus (GAS) antigens streptolysin O (SLO), DNase B, streptokinase and hyaluronidase. Antibody to the extracellular cysteine proteinase streptococcal pyrogenic exotoxin B (SPE B) and its precursor zymogen is also produced in response to GAS infections. An indirect hemagglutination test for antibody to zymogen/SPE B was established and evaluated in serum samples from 168 patients with proven (n = 27) or suspected GAS (n = 141) infections, which were also screened for antibodies using the 4 conventional tests. For comparison, sera from 56 patients infected with a variety of other pathogens, as well as sera from 16 patients infected with either S. agalactiae or S. pneumoniae and 34 sera from healthy subjects, were tested. Statistical analysis confirmed that antibody to zymogen/SPE B is a serological marker that can discriminate GAS infections. It can be ranked with the anti-SLO titer, currently the most widely used test, as a marker of an antecedent GAS infection. 相似文献

Renal arteries: navigator-gated balanced fast field-echo projection MR angiography with aortic spin labeling: initial experience 总被引:2,自引:0,他引:2
A cardiac-triggered free-breathing three-dimensional balanced fast field-echo projection magnetic resonance (MR) angiographic sequence with a two-dimensional pencil-beam aortic labeling pulse was developed for the renal arteries. For data acquisition during free breathing in eight healthy adults and seven consecutive patients with renal artery disease, real-time navigator technology was implemented. This technique allows high-spatial-resolution and high-contrast renal MR angiography and visualization of renal artery stenosis without exogenous contrast agent or breath hold. Initial promising results warrant larger clinical studies. 相似文献

A case of radiation-induced sarcoma of the chest wall is reported. Twenty-seven years 11 months after orthovoltage radiotherapy of the right breast a 69-year-old woman developed a radiation-induced osteosarcoma of the right thoracic wall. Initial diagnosis has been T-cell lymphoma of the skin. The right breast was irradiated with tangential fields and a total dose of 40 Gy, 2 Gy/day, 5 days a week. Orthovoltage treatment was performed in two courses of 20 Gy, 3 months apart. The clinical appearance of the secondary sarcoma was a diffuse infiltrated area in the irradiated breast which seemed to be fixed to the chest wall. Magnetic resonance imaging (MRI) demonstrated a mass in the right anterior thoracic wall which destroyed the fourth to the sixth rib. The tumor infiltrated the thoracic wall, including subcutaneous tissue and pericardium, as well as extending into the subphrenic space. Biopsy of the lesion revealed a poorly differentiated osteosarcoma. The patient's general condition precluded surgical or chemotherapeutic intervention; she died due to a cerebral stroke 6 months later. This case fulfilled all criteria for radiation-induced sarcoma, as there was a prior history of radiotherapy, latency period of several years, development of sarcoma within the irradiated field, and histologic confirmation of sarcoma. 相似文献

PURPOSE: Medulloblastomas represent the most frequent malignant brain tumors of childhood. They are supposed to originate from cerebellar neural precursor cells. Recently, it has been shown that Sonic Hedgehog-induced formation of medulloblastoma in an animal model is significantly enhanced by activation of the phosphatidylinositol 3'-kinase (PI3K) signaling pathway. EXPERIMENTAL DESIGN: To examine a role for PI3K/AKT signaling in the molecular pathogenesis of human medulloblastoma, we did an immunohistochemical study of the expression of Ser473-phosphorylated (p)-AKT protein in 22 medulloblastoma samples: All samples displayed p-AKT expression. To investigate if an activated PI3K/AKT pathway is required for medulloblastoma cell growth, we treated five human medulloblastoma cell lines with increasing concentrations of the PI3K inhibitor LY294002 and analyzed cellular proliferation and apoptosis. The antiproliferative effect could be antagonized by overexpressing constitutively active AKT. As the activation of PI3K/AKT signaling may be associated with alterations of the PTEN gene located at 10q23.3, a chromosomal region subject to frequent allelic losses in medulloblastoma, we screened PTEN for mutations and mRNA expression. RESULTS: Proliferation of all of the medulloblastoma cell lines was dependent on PI3K/AKT signaling, whereas apoptosis was not prominently affected. Allelic loss was detected in 16% of the cases. One medulloblastoma cell line was found to carry a truncating mutation in the PTEN coding sequence. Even more important, PTEN mRNA and protein levels were found to be significantly lower in medulloblastomas compared with normal cerebellar tissue of different developmental stages. Reduction of PTEN expression was found to be associated with PTEN promoter hypermethylation in 50% of the tumor samples. CONCLUSIONS: We conclude that activation of the PI3K/AKT pathway constitutes an important step in the molecular pathogenesis of medulloblastoma and that dysregulation of PTEN may play a significant role in this context. 相似文献
