Benign intracranial hypertension (BIH) is reported in three children from Australia and one from New Zealand, who were being treated with recombinant human growth hormone (rhGH). Three males and one female, aged between 10.5 and 14.2 y, developed intracranial hypertension within 2 weeks to 3 months of starting treatment. A national database, OZGROW, has been prospectively collecting data on all 3332 children treated with rhGH in Australia and New Zealand from January 1986 to 1996. The incidence of BIH in children treated with growth hormone (GH) is small, 1.2 per 1000 cases overall, but appears to be greater with biochemical GHD (<10IUml -1), i.e. 6.5/1000 (3 in 465 cases), relative risk 18.4, 95% confidence interval 1.9-176.1, than in all other children on the database. The incidence in patients with Turner's syndrome was 2.3/1000 (1 in 428 cases). No cases in patients with partial GHD (10–20 IUml -1) or chronic renal failure were identified. Possible causative mechanisms are discussed. The authors'practice is now to start GH replacement at less than the usual recommended dose of 14IUm-2 week-1 in those children considered to be at high risk of developing BIH. Ophthalmological evaluation is recommended for children before and during the first few months following commencement of rhGH therapy and is mandatory in the event of peripheral or facial oedema, persistent headaches, vomiting or visual symptoms. The absence of papilledema does not exclude the diagnosis.  相似文献

Carney's triad     
A 26 year old female presented with partial expression of Carney's triad. This is the first Australian report of the condition. The role of surgery and the need for vigilance to detect the occurrence of the complete triad are stressed.  相似文献

A 32-year-old woman was referred complaining of abdominal pain and bleeding at 18 weeks' gestation. The striking finding on ultrasound examination was of symmetrically enlarged echogenic fetal lungs. In addition, mediastinal compression, increased echogenicity of the kidneys and bowel, an enlarged liver of decreased echogenicity, and hydrops fetalis, as evidenced by ascites and skin edema, were all present. The differential diagnosis included upper respiratory tract obstruction and cystic kidney disease. The presence of fetal hydrops together with the other findings suggested a poor outcome, and on these grounds therapeutic abortion was recommended and performed. Subsequent postmortem findings explained all the ultrasound abnormalities on the basis of extensive fetal candida infection. The presence of a retained intrauterine contraceptive device was considered to be the likely cause and the implications of this, together with the ultrasound abnormalities and differential diagnoses, are discussed.  相似文献
