IntroductionThe main challenge of Parkinson's disease in women of childbearing age is managing symptoms and drugs during pregnancy and breastfeeding. The increase in the age at which women are having children makes it likely that these pregnancies will become more common in future.ObjectivesThis study aims to define the clinical characteristics of women of childbearing age with Parkinson's disease and the factors affecting their lives, and to establish a series of guidelines for managing pregnancy in these patients.ResultsThis consensus document was developed through an exhaustive literature search and a discussion of the available evidence by a group of movement disorder experts from the Spanish Society of Neurology.ConclusionsParkinson's disease affects all aspects of sexual and reproductive health in women of childbearing age. Pregnancy should be well planned to minimise teratogenic risk. A multidisciplinary approach should be adopted in the management of these patients in order to take all relevant considerations into account. 相似文献

To explore patients’ experiences of orthognathic treatment for facial asymmetry and their adaptation to facial changes after surgery, we did a qualitative, cross-sectional study of patients after treatment for non-cleft asymmetry at two UK sites. A total of 15 patients aged 19-40 years were approached after being identified using patient databases and clinical notes. Individual and photo-elicitation interviews were conducted covering experiences prior to treatment, during treatment, and after surgery. Interviews were transcribed and thematic narrative analysis undertaken. Participants were largely positive about their orthognathic treatment. The following themes were identified: preoperative (becoming aware, negative impacts of asymmetry, committing to treatment, establishing expectations), pre-surgery orthodontics and inpatient experiences (challenges and coping strategies, preparedness, support, and shared experiences); and postoperative (surgery as ‘worth it’, positive impacts of treatment, adapting to facial change). Undergoing orthognathic surgery was portrayed as a journey involving recognisable narratives (treatment unfinished, threat of liminality, treatment as resolution, and treatment as transformation). Patients’ experiences of facial asymmetry are associated with feeling ‘abnormal’, and negative impacts, and orthognathic treatment for facial asymmetry is worthwhile. Having the feeling that something is ‘wrong’ legitimised by clinicians allows patients access to a recognisable treatment narrative (resolution). Orthognathic treatment is also described as transformation from ‘normal abnormality’ to being ‘normal’. Nevertheless, the associated challenges can be frustrating, particularly if resolution is hard to envisage. Further psychological input could help patients cope with these challenges and the complex process of adapting to facial change. 相似文献
