Precocious puberty due to human chorionic gonadotropin-secreting pineal tumor.
We present a 9-year-old boy with central precocious puberty and hydrocephalus caused by a human chorionic gonadotropin (beta-hCG) secreting pineal tumor. High levels of beta-hCG in the serum and cerebrospinal fluid were observed in this patient. The patient received radiotherapy and chemotherapy without surgical intervention. Subsequently, significant tumor regression was observed and the serum...
متن کاملHuman chorionic gonadotropin (hCG) versus magnesium sulfate to arrest preterm
Introduction: Considering the high incidence of preterm labor and its known complications, and that human myometrium contains receptors for human chronic gonadotropin (hCG) and that hCG can inhibit myometrial contractions on vitro, made me study treating effects of hCG on preterm labor. This clinical trial study was carried out to compare the effect of hCG, and magnesium sulfate (mgso4) on pre...
متن کاملEarly Puberty Due to Ovarian Granulosa Tumor
A 7½-year-old girl is reported showing precocious puberty and large abdominal mass for a year. The right ovarial cyst removed by surgery revealed histopathologically a granulosa cell tumor. After removal of the tumor the estrogens were still increased and the signs of puberty showed no regression. This seems to be due to the hormonal activity of the metastases. Liver metastasis was present a...
متن کاملEarly pregnancy human chorionic gonadotropin (hCG) isoforms measured by an immunometric assay for choriocarcinoma-like hCG.
Human chorionic gonadotropin (hCG) exhibits molecular heterogeneity in both its protein and carbohydrate moieties. This communication describes changes in hCG isoforms detected directly in clinical samples. These isoforms, quantified in blood or urine specimens, show a progression of change throughout normal pregnancy. Early pregnancy produces a type of hCG that resembles, in terms of immunorea...
متن کاملIncreased Human Chorionic Gonadotropin Due to Hypogonadism
nonsignificant differences between cutoffs for serum and plasma and between assays are encouraging regarding the ease of interpretation by clinicians and laboratories. Also encouraging were improvements in the analytical sensitivity of these newergeneration assays. Interestingly, only 3 samples were identified as above the 99th percentile by all 3 assays. The mechanisms responsible for this lac...
