ABSTRACT
Objective:To investigate the clinical outcomes and prognosis of children who were prenatally diagnosed with solid space-occupying abdominal lesions by ultrasound.Methods:This study retrospectively enrolled 30 children with solid space-occupying abdominal lesions that were indicated by prenatal ultrasound at Children's Hospital of Fudan University from March 2015 to March 2021. Prenatal ultrasound findings, postnatal treatment, clinical outcomes, and prognosis were analyzed.Results:These subjects included 18 male and 12 female infants, with the median gestational age at the first sonographic diagnosis of 36 weeks (28 to 39 weeks). The intra-abdominal solid masses were postnatally confirmed to be located in liver, retroperitoneum, and gastrointestinal tract, which were hepatic hemangioma ( n=14), hepatoblastoma ( n=2), neuroblastoma ( n=6), abdominal teratoma ( n=4), adrenal hematoma ( n=1), adrenocortical adenoma ( n=1), hyperplasia of renal capillary ( n=1), and gastrointestinal teratoma ( n=1). The accuracy of prenatal ultrasound in detecting the location of masses was 73% (22/30) and which was 13/16 in detecting masses from liver and 9/14 in that outside the liver. Among the 30 cases, 73% (22/30) were benign tumors, and 27% (8/30) were malignant tumors (hepatoblastoma in two cases and neuroblastoma in six cases). Among 15 patients with benign tumors (hepatic hemangioma and adrenal hematoma) who received close follow-up or drug therapy, tumor/lesion regression occurred in 13 cases and the other two were observed with stable hepatic hemangiomas. Fourteen patients, including six with neuroblastoma, two with hepatoblastoma, five with teratoma, one with adrenocortical adenoma, and one with hyperplasia of renal capillary, had good prognosis after primary tumor resection or combined with postoperative chemotherapy. One hepatoblastoma case died after withdrawing treatment. The overall survival rate was 97% (29/30) with a median follow-up time of 24 months (4 to 60 months). Conclusions:Prenatal ultrasound has high accuracy in identifying the anatomic region of fetal solid space-occupying abdominal lesions. With close postnatal follow-up and proper treatment, most of the affected fetuses will have a good outcome and prognosis.
ABSTRACT
Objective To analyze the relationship between the urine iodine level in different pregnant periods of women and the thyroid function .Methods The pregnant women were randomly sampled in Foshan city and 490 cases were selected as the research subjects ,including 170 cases of early stage pregnancy ,162 cases of middle stage pregnancy and 158 cases of late stage pregnancy . According to the thyroid function ,490 subjects were divided into the normal thyroid function group and the abnormal thyroid func‐tion group .Results 140 cases(88 .61% ) in the late stage pregnancy had normal thyroid function ,which were less than 166 cases (97 .65% ) in the early stage pregnancy and 157 cases (96 .91% ) in the middle stage pregnancy ;the constituent ratio of urine iodine < 100 μg/L in the early stage pregnancy was 19 .88% (33/166) in the normal thyroid function ,which was lower than 75 .00%(3/5) in the abnormal thyroid function group .The constituent ratio of urine iodine 100 - 300 μg/L in the early stage pregnancy group was 56 .0% (93/166) ,which was higher than 0 .0% (0/4) in the of abnormal thyroid function group .Conclusion It is neces‐sary to conduct the urinary iodine monitoring in early pregnant woman ,moreover it is suggested that the thyroid function detection will be conducted in the pregnant women with urine iodine < 100 μg/L and urine iodine 100 - 300 μg/L .
