Objectives. To explore and examine students' abilities to communicate with patients during a general practice course in the final year of the curriculum and to analyse and consider this experience in relation to earlier consultation training . Setting. General practice courses in the undergraduate curriculum. Design. Qualitative data analysis was used. A special focus-group interview of experienced supervisors was performed and analysed (editing analysis). Credibility of data was tested at local seminars and conferences. Authors' experiences of observing student consultations over many years were also used. Results. A main theme, 'open invitation', emerged based on categories 'initially attentive' and 'listening attitude'. In contrast, the second main theme was 'instrumental strategy', based on the following categories: 'one-sided collection of medical facts' and 'relationship-building lost'. The students also had difficulties in devoting attention to patients' life experiences. An hourglass metaphor of students' and young physicians' progression of communication strategies is presented. The narrow part of the hourglass corresponds to an instrumental strategy at the end of undergraduate clinical education. Conclusions. An instrumental strategy may be a stage in student's consultation learning progression that interferes with communication training. A question is raised: is training of a patient-centred approach throughout the clinical curriculum needed for optimal development of consultation skills? Further research is needed to test this hypothesis. [ABSTRACT FROM AUTHOR]

Alterations in placental nutrient transfer have been implicated in fetal growth abnormalities. In pregnancies complicated by diabetes and accelerated fetal growth, upregulations of glucose transporter 1 (GLUT1) and amino acid transporter system A have been shown in the syncytiotrophoblast of term placenta. In contrast, intrauterine growth restriction is associated with a downregulation of placental system A transporters. However, underlying mechanisms of transporter regulation are poorly understood, particularly in early pregnancy. In this study, hormonal regulation of placental glucose and system A transporters was investigated. The uptake of 3-O-[methyl-(14)C]-d-glucose was studied in villous fragments isolated from first trimester (6-13 wk of gestation) and term human placenta. Villous fragments were incubated in buffer containing insulin, leptin, cortisol, growth hormone (GH), prolactin, IGF-I, or under hypo/hyperglycemic conditions for 1 h. Subsequently, 3-O-[methyl-(14)C]-D-glucose uptake was measured with and without phloretin for 70 s in first trimester tissue and 20 s in term tissue. Methylaminoisobutyric uptake was measured with and without Na+ for 20 min. Glucose uptake was unaltered by hormones or hypo/hyperglycemia. GH decreased system A activity by 31% in first trimester (P < 0.05). The uptake of glucose was 50% higher in term compared with first trimester fragments and increased markedly between 6 and 13 wk of gestation (P < 0.05). We conclude that placental glucose transporter activity is not regulated by short exposures to the hormones or glucose concentrations tested. In contrast to term placental villous fragments, system A activity was not regulated by insulin or leptin in first trimester but was downregulated by GH.

We have examined whether store-operated Ca2+ entry, a common pathway for Ca2+ entry in non-excitable tissue, is apparent in the syncytiotrophoblast of both first trimester and term human placenta. Expression of transient receptor potential (TRPC) homologues, a family of channels thought to be involved in store-operated Ca2+ entry, was also studied at the mRNA and protein levels. [Ca2+]i in syncytiotrophoblast of first trimester and term placental villous fragments was measured by microfluorimetry using the Ca2+-sensitive dye fura-2. Store-operated Ca2+ entry was stimulated using 1 microM thapsigargin in Ca(2+)-free Tyrode buffer (no added Ca2+ + 1 mM EGTA) followed by superfusion with control (Ca2+-containing) buffer. In term fragments, this protocol resulted in a rapid increase in [Ca2+]i, which was inhibited in the presence of 150 microM GdCl3, 200 microM NiCl2, 200 microM CoCl2 or 30 microM SKF96365 but was unaffected by addition of 10 microM nifedipine. It was not possible to stimulate such a rise in [Ca2+]i in first trimester fragments. Messenger RNA encoding TRPC1, TRPC3, TRPC4, TRPC5 and TRPC6 was identified in both first trimester and term placentas. From Western blotting, TRPC3 and TRPC6 proteins were detected in term, but not in first trimester, placentas, while TRPC1 protein was not detected. By immunocytochemistry, TRPC3 and TRPC4 were localised to cytotrophoblast cells in first trimester placentas and to the syncytiotrophoblast in term placentas. TRPC6 staining was present in the syncytiotrophoblast of both first trimester and term placenta, but the intensity was much greater in the latter. We propose that store-operated Ca2+ entry may be an important route for Ca2+ entry into the syncytiotrophoblast of term, but not first trimester placentas, and that in human placenta TRPC channels may underlie this entry mechanism.

Objective: To test the hypothesis that the correlation between legal abortion and socio-economic conditions, known from the time when abortion was restricted, has current validity. To evaluate the effect of social class on network support and psychological reactions., Design: Consecutive sampling and semistructured personal interviewing., Subjects: 444 women living in the city of Gothenburg and applying for legal termination of pregnancy in the first trimester., Setting: The department of gynaecology at a university hospital with primary care responsibility for legal abortions., Results: The 667 health administration districts of Gothenburg were ranked into four groups according to the mean income. Women living in lower socio-economic districts were younger. Irrespective of age, previous experience of induced abortion was more common among them (p < 0.001). Unsatisfactory network response or support was common (37%), but equally shared between the social classes. Discontinuation of oral contraception during the previous six months was twice as common among teenagers (40.0%) as among other women (p < 0.001) but without social differences. Pitman's permutation test was used for statistical analyses., Conclusion: Socio-economic conditions have a strong and inverse correlation to previous experience of induced abortion. Psychological reactions and needs did not vary with class.

In 22 patients with acute salpingitis, verified by laparoscopy, samples for attempted isolation of bacteria, Mycoplasma and Chlamydia were drawn from aspirates and cervical smears. CF-antibodies to Chlamydia were measured to acute and convalescent phase sera. Anaerobic bacteria were isolated from tubal secretions in two patients and Mycoplasmas in one patient. In two patients Chlamydia were recovered from the Fallopian tube. The serological investigation indicated Chlamydia infection in 6 patients.
