Congenital abnormalities lime received more attention in recent years due to the thalidomide tragedy and the decline in infant mortality front other sources such as infectious and nutritional diseases. The etiology of birth defects is far from understood, but the involvement of hereditary and environmental factors is widely recognized. More than 65 percent of all abnormalities are caused by unknown influences and only 5–9 percent have been attributed to proven environmental factors. Prenatal diagnosis of birth defects is becoming possible with further developments in the techniques of amniocentesis, sonography, amniography, fetography, and actual visualization of the fetus in utero. 相似文献

Background: The clinical management of patients with solitary thyroid nodule is well established; however, the evaluation of patients
with multiple thyroid nodules is controversial. The aim of this study was to assess if there is a correlation between the
risk of malignancy and number of thyroid nodules.
Design: The study cohort included 2884 patients (2410 females and 474 males) with 3274 thyroid nodules that underwent FNA under ultrasound
guidance between November 1997 and April 2004. Multiple thyroid nodules were aspirated in 360 patients; 2 in 332 (291 females,
41 males), 3 nodules in 26 (23 females, 3 males), and 4 nodules in 2 patients (1 female, 1 male). Subsequent information regarding
the histological diagnosis was obtained in the cases that underwent surgical excision.
Results: The average age for patients with single or multiple nodules was the same (51 yr). The FNA specimens were diagnosed as benign
(n=1663, 51%), neoplasm (n=880, 27%), suspicious for neoplasm or papillary carcinoma (n=234, 7%), malignant (n=187, 6%), and non-diagnostic (n=310, 9%). Surgical excision was performed in 1135 patients: 993 patients with single nodules and 142 patients with multiple
nodules. The surgical pathology diagnosis was benign in 656 nodules (52%) and malignant in 596 nodules (48%). In the malignant
category 153 tumors were papillary microcarcinoma (<1 cm). Excluding these cases, the malignancy rate was 39% in patients
with single nodules, 41% with two nodules, and 21% with three nodules.
Conclusions: The cancer risk is similar for patients with one or two nodules over 1 cm and decreases with three or more thyroid nodules. 相似文献
