Abstract: Precocious puberty can be caused by hormonally active tumours, which may arise intracranially. Treatment of these intracranial lesions traditionally involves biopsy and radiotherapy. Chemotherapy has been used recently, although radiotherapy has been given irrespective of the response to chemotherapy. We report a case of precocious puberty in an 8 year old boy due to a malignant intracranial germ cell tumour. Although one could speculate that he was cured by such combined modality therapy, the patient was left with several long-term problems. Radiotherapy was a major cause of these complications. Radiotherapy is now thought unnecessary for most extracranial germ cell tumours, as chemotherapy alone is curative in most patients. Therefore it seems appropriate to consider the elimination of radiotherapy for patients with intracranial disease. 相似文献

Extracranial metastasis is an unusual complication of most types of primary intracranial tumor. Approximately one-third of reported cases of primary intracranial choriocarcinoma have been associated with pulmonary tumor metastasis. The prognosis of such patients has been uniformly fatal. This report describes a probable long-term survivor of primary intracranial choriocarcinoma with pulmonary metastasis. The patient had a complete response to combination chemotherapy with cisplatin, etoposide, and bleomycin and is surviving free of disease >3 years from diagnosis. © 1996 Wiley-Liss, Inc. 相似文献

Precocious puberty is the appearance of physical and hormonal features of puberty before 8 years (girls) or 9 years (boys). Untreated it limits adult height and has potential psychosocial implications. It is a fairly common referral to secondary care clinics and is often seen by general paediatricians in the first instance in the UK. As an outpatient presentation it can cause anxiety owing to the breadth of potential aetiologies and concerns about missing a rare sinister cause. This short article offers a structured approach to precocious puberty to help identify any sinister causes and determine what steps you should take next. 相似文献

In Prader-Willi syndrome (PWS) hypothalamic dysfunction is the cause of hormonal disturbances, such as growth hormone deficiency
(GHD), hypogonadism, and delayed or incomplete puberty. Only a few cases of central precocious puberty (CPP) have been reported.
We describe an 8.8-year-old PWS boy, with microdeletion of chromosome 15q, who developed CPP. On admission, height was 131.1 cm
(+0.17 SD), BMI 26.2 kg/m2, pubic hair (Ph) 2, and testis 4.5 ml. We found increased growth velocity (7 cm/year), high testosterone levels, pubertal
response to GnRH test, and advanced bone age (10.6 years). An evaluation of growth hormone (GH) secretion revealed a deficiency.
Pituitary MRI was normal. LHRH analogue therapy (Leuproreline 3.75 mg/28 days i.m.) was started at 8.9 years and discontinued
at 11.3 years, when the patient had bone age of 13 years. During therapy, growth velocity, testosterone, FSH, and LH peak
decreased significantly, with no pubertal progression. Growth hormone therapy (0.24 mg/kg/week) was started at 9.5 years and
discontinued at 15.3 years because the patient had bone age of 17 years. After interrupting LHRH therapy the patient demonstrated
spontaneous pubertal progression with pubertal gonadotropin and testosterone. At 16.3 years, height was 170 cm (−0.48 SDS),
BMI 36.3 kg/m2, Ph 4, testis volume 10 ml and there was a combined hypothalamic and peripheral hypogonadism hormonal pattern (normal LH
even with low testosterone and undetectable inhibin B with high FSH). To our knowledge this is the fourth male patient with
genetically-confirmed PWS demonstrating CPP and GHD and the first with a long follow-up to young adulthood. 相似文献

We have examined the growth and skeletal maturation of 19 children (6 male, 13 female) with central precocious puberty. The aetiology in nine patients (5 male, 4 female) was secondary to a hypothalamic hamartoma. Six children (2 male, 4 female) received no treatment whereas 13 children (4 male, 9 female) were treated with cyproterone acetate in a mean dose of 68 mg/m2 per day (range, 34–260) for a mean duration of 4.5 years (range, 0.8–7.9). There was no significant difference between height SDS for bone age at the beginning and end of observation in either treated or untreated groups. No significant relationship between the mean dose of cyproterone acetate used and change in height SDS for bone age could be determined. We conclude that cyproterone acetate has no beneficial effect on the growth prognosis of children with central precocious puberty.Abbreviation GnRH

Abstract The aim of the present study was to evaluate the behavioral and affective characteristics and the changes in psychosocial functioning resulting from precocious puberty in 15 girls with central precocious puberty treated for 2 y using the GnRH agonist long-acting triptorelin, and in 5 untreated girls. After diagnosis of precocious puberty at 6.6–10.4 y of age, height, weight and pubertal development were evaluated at 3-month intervals over 2 y. Semi-structured interviews were carried out with the patient, the parents and the pediatric endocrinologists at 1, 8, 16 and 24 months after diagnosis. Standardized questionnaires (Child Behavior Checklist, Self-esteem Inventory) were administered at 1 and 24 months or 16 and 24 months, respectively. There was a mean 1.5-y delay between the observation of signs of puberty as reported by the parents and the diagnosis of precocious puberty at the first consultation of a pediatric endocrinologist. Before follow-up, all 20 girls were very concerned about physical differences from peers, particularly breast development. During therapy, breast regression to minimal or absent development occurred in 5/15 treated patients, who then no longer felt embarrassed about pubertal development in contrast to the other patients. Fear of sexuality remained obvious throughout the study in most patients. Feelings of loneliness and exemplary behavior were observed and tended to decrease in the treated patients and to increase in the untreated patients. Elevated scores of withdrawal, anxiety/depression and somatic complaints at Child Behavior Checklist were still observed after 2 y. These changes in behavioral and affective characteristics appeared to be related neither to height and weight, nor to development of pubic hair, which progressed in most patients. After 2 y, the physical differences remained a concern for 13 girls and the risk of short adult stature for 6. In summary, some behavioral and affective characteristics and particularities in psychosocial functioning are observed in girls with precocious puberty. During treatment with long acting triptorelin, problematic behavior and functioning decrease slightly, particularly in the few girls showing breast regression to minimal or absent development. 相似文献
