OBJECTIVE To evaluate karyotype-specific ear and hearing problems in young-adult patients with Turner syndrome (TS) and assess the effects of previous treatment with oxandrolone (Ox). STUDY DESIGN Double-blind follow-up study. SETTING University hospital. PATIENTS Sixty-five TS patients (mean age, 24.3 yr) previously treated with growth hormone(More)
Noonan syndrome (NS) and Turner syndrome (TS) are associated with cognitive problems and difficulties in affective information processing. While both phenotypes include short stature, facial dysmorphisms, and a webbed neck, genetic etiology and neuropsychological phenotype differ significantly. The present study examines putative differences in affective(More)
Turner syndrome (TS) is the result of (partial) X chromosome monosomy. In general, the diagnosis is based on karyotyping of 30 blood lymphocytes. This technique, however, does not rule out tissue mosaicism or low grade mosaicism in the blood. Because of the associated risk of gonadoblastoma, mosaicism is especially important in case this involves a Y(More)
CONTEXT Besides short stature and gonadal dysgenesis, Turner syndrome (TS) is associated with various abnormalities. Adults with TS have a reduced life expectancy, mainly related to structural abnormalities of the heart and aorta, and an increased risk of atherosclerosis. OBJECTIVE Our objective was to investigate the yield of an initial standardized(More)
Turner syndrome is the result of the complete or partial absence of one X-chromosome. As well as short stature and gonadal dysgenesis, a wide range of abnormalities which may not present themselves until adulthood, are seen in nearly every organ system. Adult women with this syndrome have a reduced estimated life expectancy due to the greatly increased risk(More)
The aim of the study was to report otologic and audiologic characteristics in a group of children with Turner syndrome (TS) and correlate these findings to karyotype. Additionally, we give recommendations for the otologic care of these children. Sixty children (age 1.7-21.2 years) were included in this retrospective study. Medical history and karyotypes(More)
OBJECTIVE Short stature is a prominent feature of Turner syndrome (TS), which is partially overcome by GH treatment. We have previously reported the results of a trial on the effect of oxandrolone (Ox) in girls with TS. Ox in a dose of 0.03 mg/kg per day (Ox 0.03) significantly increased adult height gain, whereas Ox mg/kg per day (0.06) did not, at the(More)
There has been no consensus regarding the efficacy and safety of oxandrolone (Ox) in addition to growth hormone (GH) in girls with Turner syndrome (TS), the optimal age of starting this treatment, or the optimal dose. This collaborative venture between Dutch, UK and US centers is intended to give a summary of the data from three recently published(More)
Turner syndrome (TS) is the result of (partial) absence of one X-chromosome. Besides short stature, gonadal dysgenesis and other physical aspects, TS women have typical psychological features. Since psychological effects of androgen exposure in childhood probably are long-lasting, we explored long-term psychological functioning after oxandrolone (Ox)(More)
OBJECTIVE Analysis of the value of intraoperative parathormone (PTH) measurement in patients with primary hyperparathyroidism. DESIGN Prospective study. METHOD Evaluation of the value of intraoperative measurement ofPTH in 75 patients (including 19 patients with multiple endocrine neoplasia(MEN)-1 syndrome) who underwent parathyroidectomy in 2001-2005.(More)
