Abstract: Background: The media both creates and reflects public opinion. The way in which health professionals are depicted in the media is likely to influence views held by and about different health professions. The aim of this study was to examine how midwives and obstetricians are reported in English language web-based news reports from around the world. Methods: News alerts from the Internet search engine Google were created to search for the terms “midwife,”“midwives,”“midwifery,”“obstetrics,” and “obstetricians.” These alerts were received over a 12-month period (May 1, 2006–April 31, 2007), downloaded, and analyzed using quantitative content analysis. Results: A total of 522 web-based news reports for midwifery and 564 for obstetrics (n = 1,086) were found. Dominant categories for midwives were: “mainstreaming midwives” (models of care/rise of midwifery) (28%); “the Cinderella of the maternity care” (workforce/industrial) (27%); “delivering the baby with your hands tied” (funding, insurance, and legislation) (21%); “ask the expert” (education, research, and health advice) (8%), “recognizing midwives” (awards and announcements) (7%), “unsafe midwives” (litigation) (6%); and “the art of birth” (books, film, and photographs) (2%). Dominant categories for obstetricians were: “ask the expert” (research and advice) (26%); “doctors are heroes amongst us” (awards and announcements) (19%); “obstetric workforce woes” (workforce/industrial) (19%); “new frontiers” (trends in care and new technology) (17%); “the disappearing obstetrician” (insurance and litigation) (10%); and “human-interest news reports” (9%). Obstetricians were more likely to be recognized as experts on pregnancy and birth and receive public recognition compared with midwives. Midwives were more likely to be depicted as struggling to be a mainstream option while being hampered by lack of funding, insurance, and legislative barriers. Conclusions: Although midwives have rising acceptance, they still struggle with recognition. Obstetricians have both acceptance and recognition. Countries where midwifery is a mainstream option have more news reports related to midwifery than obstetrics. Different issues appear more dominant in some countries, such as work force in the United Kingdom and funding, insurance, and legislation in the United States. (BIRTH 39:1 March 2012) 相似文献

Objective: Our purpose was to determine whether primary and preventive care is practiced by a university obstetrician-gynecologist group practice.Study design: A retrospective chart review spanning 2 years of four academic physicians' private practices was performed. A total of 335 patients were reviewed with 739 patient encounters and 1032 patient problems identified. The definition of a primary care physician according to The American College of Obstetricians and Gynecologists was used to standardize data collection and evaluation.Results: Obstetric complaints accounted for 27.7% of all visits, whereas 65.4% were for gynecologic problems. Almost 7% of all complaints were neither obstetric nor gynecologic, and of those 74.6% were primary care problems completely managed by the obstetrician-gynecologist. Only 19.7% of these were referred for management. More than 89% of all encounters () involved some element of primary care.Conclusion: This study provides evidence that the majority of health care provided by the obstetrician-gynecologists is primary care. 相似文献

We present a case of a lost broken needle during repair of a vaginal tear following delivery. The woman was not informed at
that time. Only twenty years later a pelvic X-ray visualised the fragment by chance. From that day on she complained about
lower abdominal chronic pain and insisted on a hysterectomy. The case considers moving of foreign bodies and as a cause of
chronic pain and relates to open information even 20 years later.

本文阐述了中国西医产科学的发展历史。由于传统封建思想的阻碍,我国现代产科学的起步较晚,1911年在福建省建立了我国第一所产科病房。1930年以前孕产妇及新生儿死亡率比英美高4~5倍,1930年后,建立助产学校,开展孕期保健及骨盆测量,不断改进对病理妊娠的诊断及妊娠合并症的处理,这些均促进了中国近代西医产科学的进步,也为建国后的发展奠定了基础。 相似文献

Female fetal sex was assigned based on downward direction of the genital tubercle at 14 weeks' gestation. Subsequently, amniocentesis performed due to the finding of an echogenic focus in the left ventricle revealed a male karyotype. Sonographic examination at 22 weeks' gestation revealed a markedly curved penile shaft. Power Doppler at that time demonstrated a urine jet emanating from the penile base, verifying the diagnosis of penoscrotal hypospadias. We therefore suggest that female fetal sex assignment should be based on the demonstration of the 2 or 4 parallel lines representing the labial folds and not only upon the demonstration of the downward direction of the genital tubercle. 相似文献

Chorioangioma is a benign vascular tumor of the placenta arising from primitive chorionic mesenchyme. Large (>4 cm) chorioangiomas are much rarer and are often associated with maternal and/or fetal complications. We describe the sonographic features of a large placental chorioangioma with normal outcome. 相似文献
