Postpartum ultrasound investigation of a woman with unremitting fever and right flank pain after Cesarean section revealed an extensive thrombosis of the right ovarian vein which extended into the inferior vena cava. Computed tomography was required to substantiate the diagnosis. Medical treatment with intravenous urokinase and heparin and antibiotics was successfully performed. During the postpartum period, the possibility of ovarian vein thrombosis should be considered in febrile patients with abdominal pain who are not responding to antibiotics, and imaging studies such as ultrasound and computed tomography should be performed early for prompt diagnosis and therapy.

In this paper, we present the results of ion shower implantation to adjust threshold voltages on ELC (excimer laser crystallized) poly silicon thin film transistors. We observed that the threshold voltages of poly Si TFT strongly depended on the shower implantation dose, not the shower implantation energy for the 500 Å-thick active silicon layer. The threshold voltages for the reference, dose 5×1011 cm-2, and 1×1012 cm-2 cases were 0.30V, 1.25V, and 2.04V, respectively. We conclude that the threshold voltage can be appropriately adjusted by tuning the dose of the counter doping shower implant and its DIBL can still be suppressed to within an acceptable level.
