The determination of goiter prevalence in children by thyroid ultrasound is an important tool for assessing iodine deficiency disorders. The current World Health Organization/International Council for the Control of Iodine Deficiency Disorders (WHO/ICCIDD) normative values, based on thyroid volume in iodine-sufficient European children, have recently been questioned, as thyroid volumes in iodine-sufficient children from the USA and Malaysia are smaller than the WHO/ICCIDD reference data. Our objective was to describe ultrasonographic thyroid volumes in a representative national sample of iodine-sufficient Swiss school children, and to compare these with the current reference data for thyroid volume.
This study aimed to look at the prevailing practice patterns of gynaecologists with regards to prophylactic oophorectomy and usage of hormone replacement therapy. Questionnaires were sent to the first 200 gynaecologists listed in the membership list of the Obstetrical and Gynaecological Society of Malaysia. The response rate was 30%. The results showed that most gynaecologists would perform prophylactic oophorectomy after the age of 49 years. The result was equivocal for the ages between 45 to 49 years. Of those who retained the ovaries at the age of 45 to the menopause, 55% did so because the ovaries were still functional. Almost all gynaecologists would prescribe hormone replacement therapy (HRT) after oophorectomy and the most commonly prescribed form was the oral type. Thirty-five per cent of gynaecologists claimed that more than 80% of their patients were compliant to HRT. The reasons perceived for the poor compliance were mainly poor knowledge and misconception.
