Study ObjectiveTeenage pregnancies and associated induced abortions represent an important public health issue. The aim of this study was to investigate the prevalence, the time trends, and associated factors of teenage induced abortions in Greece.DesignA cross-sectional study was conducted between 2018 and 2019.SettingThird Academic Department of Obstetrics and Gynecology of the Aristotle University of Thessaloniki.ParticipantsAll pregnant women who underwent a second trimester anomaly scan were eligible for the study.Interventions and Main Outcome MeasuresEpidemiological characteristics were recorded and 5 age groups were created. Trends in the rates of teenage induced abortions were analyzed and we compared several parameters between women with and without history of abortions.ResultsOverall, 3370 women were eligible and agreed to participate in the study. The prevalence of women who reported a history of at least 1 abortion at 15-19 years was 9.7% (n = 328/3370). The abortion rates across the 5 age groups were: 20-24: 7.5%; 25-29: 8.4%; 30-34: 8.2%; 35-39: 12%; and 40 years and older: 13.9%. Moreover, a history of 1 or more teenage abortions was more common in multiparous women (58.2% vs 46.5%; P < .001; odds ratio, 1.605; 95% confidence interval, 1.274-2.022) and in current smokers (27.4% vs 11%; P < .001; odds ratio, 3.066; 95% confidence interval, 2.346-4.008).ConclusionA significant decline in the teenage induced abortion rates was identified in the study population. A history of teenage induced abortion was associated with smoking and multiparity. More efforts are needed to provide appropriate education on effective contraception and family planning. 相似文献

ObjectivesPsychoanalytical and other theories of autism are mainly based on infantile clinical observation. Considering this, the perspective of the personal evolution of autistic persons during their teenage years and adulthood opens questions leading to a necessary reassessment of theoretical knowledge. Over the last decade, our understanding of autistic pathologies has increasingly underlined the importance of sensory elements in their symptomatic expression. The main objective of this theoretical reflection is to formulate new theoretical suggestions to help better understand the evolutions of autistic persons. Notably, this includes hypotheses allowing us to articulate the psychic functioning of autistic persons to other psychopathological functioning.MethodThis research is based on autobiographical writing by autistic persons, leading to a phenomenological point of view, which will be completed with elements of clinical experience. This corpus of knowledge offers insight into dismantling, stimming, and sensory pursuit, allowing us to better understand the peculiar forms of the use of the sensorial in the psychic functioning of autistic subjects. It will refer to existing psychoanalytical writing on autism, thereby suggesting a new psychopathological understanding of the archaic dimension made visible by autistic pathologies.ResultsDifferences between different forms of autism and psychosis are interrogated, in order to further understanding of clinical situations where this distinction is less evident. Autobiographical writing by autistic persons promotes understanding of the ways in which the sensory dimension plays a specific part in psychic functioning. What psychic processes are present in the sensory part of mental functioning of those subjects is theorized. Focusing on self-stimulatory behavior and sensory pursuit as they are seen in autism, it is suggested that psychic functioning builds itself with these sensory elements, thus stabilizing the psychic apparatus. The notion of autistic functioning is introduced to explain subjects’ reliance on the sensorial register as a stabilizer of the psychic apparatus. Psychic drives invest sensory sensations which are preorganized by the Id in order to become a perception. Then, these particular uses of sensory elements and perception find a way to persist in the subject's psychic functioning in diverse forms. This leads to a persistence of archaic functioning in the psyche that also can invest in other functioning. Three outlooks are explored. First, that autistic pathologies can develop in many ways, including evolutions where psychic functioning is closer to what exists in psychotic functioning. Then, how some psychotic subjects can make use of autistic functioning to help them deal with splitting anxiety. Lastly, autistic functioning can also punctually exist in certain types of trauma, opening the question of its existence outside of psychosis and autism.DiscussionThe notion of autistic functioning makes it clears how some archaic functioning, as seen un autistic persons, can maintain itself throughout subjects’ development. In the meantime, other psychic functioning appears and develops during teenage years and adulthood. Furthermore, this notion opens the question of differential diagnosis with psychosis and the possibility for autistic functioning to exist outside of autism.ConclusionsThe notion of autistic functioning leads to another way of thinking about the personal evolution of autistic persons as they get older. It, nonetheless, will require further reflection, particularly as regards evaluating its clinical relevance, as well as its usefulness for differential diagnosis. 相似文献

By exposing on the institutional level the sufferings of his present, the adolescent talks to us about his history, the damaged, destroyed or uninhabited links which mark out his life trajectory and arise in this “meantime” of his existence in so many painful shards in the internal world of his psyche and in the body. During their journey through the care institution, we work with these adolescents and their families, in this space-time, on what could help to reduce the internal breaking lines so that they can again start moving their subjective capacities to think and act in the world. Our work ethic is based on the specific capacity of each institutional actor to deploy his/her containing psychic envelopes around young patients; symbolized deployment of the containing function by the time to think about the care for the caregiver, the time to consent to it in a safe way for the adolescent, then for the latter the time once again acceptable to explore the field of possibilities. 相似文献

Background
The significance of subclinical vitamin D deficiency in the pathogenesis of fractures in children and adolescents currently remains unclear.Objective
We aimed to determine the prevalence of vitamin D insufficiency and its effect on bone mineral density (BMD) and bone mineral content (BMC) values in a collective of Swiss Caucasian children with a first episode of appendicular fracture.Design and methods
One hundred teenagers with a first episode of appendicular fracture [50 upper limb fractures (group 1) and 50 lower limb fractures (group 2)] and 50 healthy controls (group 3) were recruited into a cross-sectional study. The BMC and BMD values were measured by dual-energy X-ray absorptiometry, and serum 25 hydroxyvitamin D [25(OH)D] was assessed by electrochemiluminescence immunoassays.Results
From the 100 injured teenagers in the study, 12 % had deficient vitamin D levels (<20 ng/mL; <50 nmol/L) and 36 % had insufficient levels (≥20 <30 ng/mL; ≥50 <78 nmol/L), whereas 6 and 34 % of healthy controls were, respectively, vitamin D deficient and insufficient. There were no significant differences for serum 25(OH)D levels, L2–L4 BMD Z-score, and L2–L4 BMC Z-score variables (p = 0.216) between the three groups nor for the calcaneal BMD Z-score variables (p = 0.278) between healthy controls and lower limb fracture victims. Investigations on the influences of serum 25(OH)D on BMD and BMC showed no correlation between serum 25(OH)D and L2–L4 BMD Z-scores (r = −0.15; p = 0.135), whereas low but significant inverse correlations were, surprisingly, detected between serum 25(OH)D and calcaneal BMD Z-scores (r = −0.21; p = 0.034) and between serum 25(OH)D and L2–L4 BMC Z-scores (r = −0.22; p = 0.029).Conclusions
A significant proportion of Swiss Caucasian teenagers were vitamin D insufficient, independent of limb fracture status, in our study. However, this study failed to show an influence of low vitamin D status on BMD and/or BMC of the lumbar spine and heel. 相似文献9.
