Radiation-induced neuropathy is a rare but well recognized clinical entity although peripheral nerves are considered to be relatively resistant to irradiation. We report three patients with radiation-induced lumbosacral plexopathy, whose characteristic clinical and electrophysiological features can be summarized as follows: 1) 55-58 year old women who were previously treated with radiotherapy for uterine cervix carcinoma: 2) the latent period is to 10 from 13 years: 3)predominantly motor involvement with slowly progressive paraparesis, asymmetrical onset and worse in distal muscle group: 4) painless at onset, with variable degree of sensorv changes: 5)decreased or absent knee and ankle jerks :6)axonal damage in electrophysiologic study: 7)frequent myokymic discharges. Myokymic discharges occur in bursts at regular rate of 0.1 to 8 Hz. In myokymic bursts with more spikes, interburst interval is longer but interspike Interval is shorter.

OBJECTIVE: The changes of the production of nitric oxide in preeclampsia are still controversial. To determine the changes of nitric oxide production in preeclamptic pregnancies, NOS activity and eNOS and iNOS expression in preeclamptic placentae were compared with those in normal placentae, and to determine the changes of nitirc oxide production according to the sites of placenta, NOS activity and eNOS expression in preeclamptic placentae were also compared with those in normal placentae. METHODS: Human placentae were obtained from 15 normal and 15 preeclamptic pregnant women at the time of cesarean section. NOS activity was assessed by measuring the conversion of [3H]-arginine into [3H]-citrulline. The eNOS and iNOS expression were assessed by using western blot analysis. Data were analyzed by Student t-test and paired t-test where appropriate. RESULTS: The NOS activity(judged by measurement of [3H]-citrulline production) was significantly increased in preeclamptic placentae compared to normal(P<0.05). In normal and preeclamptic pregnant placentae, the NOS activity in main stem villi was increased compared to that in terminal villi. However, the difference of NOS activity between main stem villi and terminal villi was not significant(P>0.05). Quantification of the autoradiographic images demonstrated that the integrated optical density of the immunoreactive bands of eNOS were significantly lower in preeclamptic placentae compared to normal(p<0.05). Conversely, the integrated optical densities of the bands of iNOS were significantly higher in preeclamptic placentae compared to normal(p<0.05). CONCLUSIONS: Although the eNOS expression in preeclamptic placentae was lower than that in normal placentae, the NOS activity was significantly higher in preeclamptic placentae than that in normal in this study. These are result from increased production of iNOS in the compensatory mechanisms for the decreased nitric oxide production in pre-eclamptic placentae.

Despite recent improvements in the intensive care for postpartum hemorrhage, it remains one of the leading causes of maternal mortality and morbidity for obstetricians. Because it is difficult to prevent or predict postpartum hemorrhage, it is important to manage any such patients correctly and promptly. Management of postpartum hemorrhage may vary greatly among patients, depending on the etiology of the bleeding, available treatment options, and the patient's desire for future fertility. When managing postpartum hemorrhage, it is necessary to balance the use of conservative management with the need to control the bleeding and achieve hemostasis. Uterine massage and compression, and the administration of uterotonics such as oxytocin, ergometrine, and prostaglandins are primary, conservative, and noninvasive management techniques for patients with postpartum hemorrhage. Relatively noninvasive procedures such as curettage of remnant tissues, vaginal packing, repair of laceration, and percutaneous angiographic embolization can also be performed. In cases where these management techniques fail, surgical alternatives such as uterine or internal iliac artery ligation, uterine compression sutures, or hystrectomy are used. Surgical treatment of postpartum bleeding, performed as an appropriate and timely intervention, is life-saving. The management of postpartum bleeding requires a multidisciplinary approach with timely and efficient communication between clinical specialists and preserving fertility.
