Quality is the most important feature that a consumer expects from food. There is no objective concept for quality, but "quality" exists in the individual consumers opinion. The quality of a product is, from the consumers point of view, not just its characteristic, but the subjective feeling of each consumer. Empirical examinations show the existence of different "consumer-categories", where the criteria of quality differ elementary. Additional to this subjective opinion the discussion in the media about substances in food that may be harmful to ones health confuses the consumer and leads to a semantic separation between the terms "Eating" and "Nutrition". Especially meat-products are effected by this discussion. The recent increase of a consumers uncertainty concerning meat-products, which is influenced by information and reports about bad conditions in livestock breeding and animal transports as well as conditions in slaughterhouses is reflected. The consumers confrontation with the origin of meat-products causes feelings of guilt and therefore a decreasing request for meat. Although, there is no long term change in eating habits for the majority of the population because of the aspects mentioned before, it must be worked towards an improvement concerning this particular situation as soon as possible.  相似文献

The indications for the employment of Althesin in caesarean section are explained and a substantially favourable opinion is expressed on its clinical effects. Absence of neonatal depression is attributed both to the distribution and metabolism of the drug, and to the features of foetal circulation at term.  相似文献

BACKGROUND: To investigate the guidelines for patient selection and drug regimens for application of antibiotic prophylaxis in relation to cesarean section in the maternity clinics in Denmark. METHODS: A questionnaire to all the Danish maternity clinics that perform cesarean section, concerning indications for application of antibiotic prophylaxis and antibiotic regimens to patients undergoing acute and elective cesarean section. RESULTS: All departments (n = 48) returned the questionnaire. Twenty departments (46%) provided written guidelines for antibiotic prophylaxis. Four departments (8%) used antibiotic prophylaxis to elective cesarean sections, 25 departments (52%) applied antibiotics to all emergency sections. In the presence of the rupture of membranes or prolongation of labor (> 12 hrs) 58% and 63% of the departments applied antibiotic prophylaxis, respectively. The most infrequent first choice drug was cefuroxim, employed by 27 departments (56%). Concerning timing, 21 departments (44%) applied antibiotics after cord clamping and 13 departments (27%) before incision. CONCLUSION: We propose a nation-wide prospective investigation on the rate of infections associated with cesarean section to set up rational guidelines for antibiotic prophylaxis.  相似文献

After observing spikes in the Doppler signal of cerebral arteries of patients with neurologic symptoms and prosthetic heart valves, we then studied two groups of patients with prosthetic heart valves: seven patients with neurologic symptoms and 65 asymptomatic patients. Using transcranial Doppler sonography of the middle cerebral artery, we found Doppler spikes in six symptomatic and 24 asymptomatic patients with mechanical heart valves. No spikes were found in one symptomatic and 21 asymptomatic patients with biological valves or in 20 asymptomatic patients with mechanical valves. We concluded that gas cavitation during the opening or closure of the valve, producing bubble emboli, is the most probable explanation for these Doppler spikes in patients with mechanical prosthetic heart valves.  相似文献

The first reported caesarean section in Norway was performed on 20 August 1843 by a general practitioner, Lars Thalian Backer (1812-84). The operation took place in Lardal, Vestfold County, on a 27 year old woman who had been in labour for six days. The outcome was disastrous; she was delivered of stillborn twins and died 2 1/2 days after the operation. In the 19th century, infection, bleeding and thromboembolic disease made caesarean section a dangerous operation, and only 26 such operations are known in Norway, most of them performed outside hospitals. The first caesarean section in Norway resulting in a living child was performed in 1849, but no mother survived the operation before 1890. We recapitulate the caesarean section of 1843; Dr Backer and his qualifications for operative obstetrics; and the state of instrumental and surgical obstetrics in Norway at that time.  相似文献

The investigation of 222 patients with caesarean section showed an increasing bacterial invasion of the amniotic fluid, when in the patients preoperative was found: - clear or green colored (meconic) amniotic fluid and intact membranes, - clear amniotic fluid with ruptured membranes and - green-colored (meconic) amniotic fluid and ruptured membranes. In support to some conceptions from the literature a perioperative prophylaxis with antibiotics is recommended in the groups, which are potentially endangered postoperatively.  相似文献

The nucleotide sequences of the ribulose-1,5-bisphosphate carboxylase/oxygenase large subunit gene (rbcL) of Glycyrrhiza glabra, G. uralensis, G. inflata, G. echinata, and G. pallidiflora have been determined to construct the phylogenetic tree. In the phylogenetic tree based on the rbcL sequences, the five Glycyrrhiza species were divided into two groups: the three glycyrrhizin-producing species G. glabra, G. uralensis, and G. inflata; and the two glycyrrhizin-nonproducing species G. echinata and G. pallidiflora. Among the three glycyrrhizin-producing species, only two nucleotide substitutions were observed between the rbcL sequence of G. glabra and G. uralensis, and the sequence of G. uralensis was identical to that of G. inflata, indicating that the three glycyrrhizin-producing species are closely related.  相似文献

Over a period of 10 years (1980-1989) in the Clinic of Obstetrics and Gynaecology in Stara Zagora 740 women have delivered children after a previous caesarean operation. On the basis of this material the author has studied the vaginal delivery complications for the mother after a previous caesarean operation and in the cases of a second planned caesarean operation. The alternative and correlational analysis of the clinical data has shown that the complications for the mother in the latter group are 3 times more than those in the former group.  相似文献

We report a successful surgical treatment of an infective thoracic aortic aneurysm ruptured to the left lung. A 63-year-old man who had been suffering from fever and cough showed twice of hemoptysis. Chest CT revealed a descending thoracic aortic aneurysm ruptured to the left lung. A semiemergent operation was performed. At operation, aneurysm of descending thoracic aorta was found adherent to the left lung. Aneurysmectomy with left pneumonectomy was carried out. The postoperative course of the patient was uneventful. Conceivably, in order to avoid massive intraoperative bleeding during division of dense adhesion and postoperative graft infection, concomitant lung resection is necessary.  相似文献

OBJECTIVE: We report a 10-year experience with vaginal birth after cesarean section in women with twins. STUDY DESIGN: Data were gathered from labor and delivery records and maternal and neonatal hospital charts. Women with a vertical uterine scar, a previous uterine rupture, an unrepaired dehiscence, or obstetric contraindications to labor were excluded from a trial of labor. Full-thickness uterine defects requiring intervention were classified as ruptures; all others were classified as dehiscences. RESULTS: Between Jan. 1, 1985, and Dec. 31, 1994, at Los Angeles County/University of Southern California Women's Hospital, 210 women with previous cesarean births were delivered of twins. One hundred eighteen (56%) underwent repeat cesarean delivery without a trial of labor. Ninety-two (44%) undertook a trial of labor with no uterine ruptures and no increase in maternal or perinatal morbidity or mortality. CONCLUSIONS: In women with twins a trial of labor after a previous cesarean section is a safe and effective alternative to routine repeat cesarean delivery.  相似文献

BACKGROUND: As the operating births (caesarean section) increase, many surgical equipes have been compelled to revise operating techniques in order to reduce fetus extraction times and the whole expense of operation without renouncing, at the same time to beauty advantages. With Stark technique, that we have modified, we have obtained all these aims, improving at the same time patients' postoperative course as well succeeding to extract the fetus in about five minutes. In the '70 Cohen explained the utility of a transiliac incision allowing the access to abdominal cavity with rectus muscles unsticking in an area in which these muscles should present a less adhesiveness. METHODS: Since 1988 Stark has used Cohen's technique changing however uterus closing times, peritoneal membranes and abdominal walls. Our technique is different since we performed the incision according to Pfannestiel. RESULTS: The times are considerably reduced to 4.8 minutes for fetus extraction and in postoperative time the complications are drastically reduced too (infection, pain, hematoma, adhesions). CONCLUSIONS: Therefore we can surely say that this kind of technique can be used with success in all gynaecological surgery, in extrauterine pregnancies and adnexial tumefactions (not malignant). Personal opinion is that spinal anesthesia is the best analgesic technique.  相似文献

Endometriosis in postoperative abdominal wall scar after cesarean section is rarely observed. In professional literature, only single cases are reported. The author presented 27 cases of this diseases. The women were treated in the Gynaecology and obstetrics Department of Medical School in Lód?, in 1985-1994. Because of the small response to pharmacological treatment, the treatment of choice was surgical of the lesion. In the article, the literature concerning the disease is presented.  相似文献

OBJECTIVE: The assess the incidence of tardive dyskinesia (TD) in a sample of adolescents treated with neuroleptic medication and to identify the presence of any risk factors for TD within the affected group. METHOD: A retrospective chart review was conducted for 40 cases. The Abnormal Involuntary Movement Scale (AIMS) was used to measure side effects from medication at 6-month intervals over 2 years. Drug exposure was converted to chlorpromazine (CPZ) equivalent and the presence of risk factory for TD, such as a diagnosis of affective disorder, medication noncompliance, early age of illness onset, and concomitant antiparkinsonian medication, was also noted. RESULTS: Of the 40 cases reviewed, 2 patients (5%) met diagnostic criteria for TD, and another 5 patients (12.5%) showed symptoms of TD. CONCLUSIONS: TD is a serious risk at any age. Medication noncompliance, early age of illness onset, and concomitant use of antiparkinsonian medication may increase susceptibility to TD and should be carefully monitored.  相似文献
