Bone mineral density in partially recovered early onset anorexic patients - a follow-up investigation

<p>Abstract</p> <p>Background and aims</p> <p>There still is a lack of prospective studies on bone mineral development in patients with a history of early onset Anorexia nervosa (AN). Therefore we assessed associations between bone mass accrual and clinical outcomes in a former clinical sample. In addition to an expected influence of regular physical activity and hormone replacement therapy, we explored correlations with nutritionally dependent hormones.</p> <p>Methods</p> <p>3-9 years (mean 5.2 ± 1.7) after hospital discharge, we re-investigated 52 female subjects with a history of early onset AN. By means of a standardized approach, we evaluated the general outcome of AN. Moreover, bone mineral content (BMC) and bone mineral density (BMD) as well as lean and fat mass were measured by dual-energy x-ray absorptiometry (DXA). In a substudy, we measured the serum concentrations of leptin and insulin-like growth factor-I (IGF-I).</p> <p>Results</p> <p>The general outcome of anorexia nervosa was good in 50% of the subjects (BMI ≥ 17.5 kg/m², resumption of menses). Clinical improvement was correlated with BMC and BMD accrual (χ²= 5.62/χ²= 6.65, p = 0.06 / p = 0.036). The duration of amenorrhea had a negative correlation with BMD (r = -.362; p < 0.01), but not with BMC. Regular physical activity tended to show a positive effect on bone recovery, but the effect of hormone replacement therapy was not significant. Using age-related standards, the post-discharge sample for the substudy presented IGF-I levels below the 5^thpercentile. IGF-I serum concentrations corresponded to the general outcome of AN. By contrast, leptin serum concentrations showed great variability. They correlated with BMC and current body composition parameters.</p> <p>Conclusions</p> <p>Our results from the main study indicate a certain adaptability of bone mineral accrual which is dependent on a speedy and ongoing recovery. While leptin levels in the substudy tended to respond immediately to current nutritional status, IGF-I serum concentrations corresponded to the individual's age and general outcome of AN.</p

Short-term and intermediate-term outcome in adolescent eating disorders

Within a prospective longitudinal outcome study of the eating disorders with onset during adolescence, 26 former patients were reassessed at short-term (19-38 months) and intermediate-term (48-72 months) follow-up periods. It was shown that the outcome was worse at short-term follow-up. In addition, the changes of diagnostic categories within the spectrum of the eating disorders were studied. It is concluded that outcome studies require repeated assessments to study the various patterns of course of the eating disorders

Quadro clínico do transtorno obsessivo-compulsivo

<abstract language="eng">Obsessive-compulsive disorder is a very heterogeneous condition, not always easy to be identified. Obsessions are intrusive thoughts, impulses or images that cause anxiety or other emotional discomfort, whereas compulsions are repetitive behaviors or mental acts voluntarily performed to counterbalance or minimize the discomfort, or magically prevent any feared events. The most common symptoms are contamination, aggressive, somatic and sexual obsessions and washing, checking, repeating, counting and ordering compulsions. Patients usually have multiple symptoms simultaneously, which often change over time. Although the insight is typically preserved, it varies among patients and also fluctuates in the same patient in different ocasions. The main features are: exacerbated appraisal of risks, pathological doubts and incompleteness, as well as excessive sense of responsibility and guilt and thought/action fusion. As patients frequently feel ashamed of their symptoms, they can be reticent about them. Consequently, it usually takes time till they get adequate treatment
