    ABSTRACT: Thalassemia is a common hematological disease in Southeast Asia. Extramedullary hematopoiesis is common sequelae in thalassemic patients but extramedullary hematopoiesis in the spinal epidural space that leads to paraparesis in pregnancy is very rare. We managed a thalassemic patient with extramedullary hematopoiesis and spinal cord compression during pregnancy. The diagnosis was made on clinical features and magnetic resonance imaging (MRI) showing a paravertebral mass infiltrating the epidural space. She was treated successfully with repeated blood transfusions until delivery. Fetal growth restriction was found but otherwise the fetus was clinically normal. She had an uneventful recovery when she was seen 6 weeks after delivery.

    ABSTRACT: To assess the value of transvaginal sonographic hydrotubation with color Doppler flow (TSH) as a test of tubal patency. Thirty-nine women undergoing infertility investigation at Chulalongkorn Hospital participated in this prospective, blind comparative study. Before diagnostic laparoscopy (DL) with chromopertubation, TSH was performed using the SSD 680, 5 MHz vaginal ultrasound probe and 20-50 ml of saline was injected into the uterine cavity. Nine cases could not be evaluated properly. Of the 30 cases, there were complete agreements between TSH and DL in 24 (80%), partial agreement in 5 (16.67%) and non-agreement in 1 (3.33%). TSH had sensitivity 100%; specificity 84.62%, positive predictive value 50%, negative predictive value 100%, false positive rate 15.38%, but no false negative rate. TSH is a simple diagnostic procedure for screening of tubal patency. However, other confirmatory test is needed if tubal occlusion is suspected.
