We report on two cases of diamniotic dichorionic pregnancy with delayed delivery of the second twin. Case 1 was a 29-year-old woman with a twin pregnancy at 19 weeks and 0 day presenting with a preterm rupture of the membranes (PROM) of the first twin. The patient was treated with ritodrine and systemic broad-spectrum antibiotics. Six hours after admission, the first twin was delivered stillborn without complication. At 23 weeks and 5 days, preterm labor resulted in and the second twin being delivered stillborn at a weight of 564 g. The interval between the first and second delivery was 33 days. Case 2 was a 30-year-old woman with a twin pregnancy at 15 weeks and 4 days presenting with amniotic fluid leakage. PROM was found, and she was treated with ritodrine and systemic broad-spectrum antibiotics. The next day, the first twin was delivered stillborn. At 26 weeks, due to adverse effects, ritodrine was changed to isoxsuprine and magnesium sulfate to control uterine contractions. At 33 weeks and 5 days, onset of labor was observed, and 11 hours after the cessation of treatment with isoxsuprine and magnesium sulfate, a viable female fetus was delivered by spontaneous vaginal delivery, weighing 1,806 g. The mother developed atonic bleeding of the uterus immediately after delivery.;The interval between the first and second twin deliveries was 33 days in case 1 and 127 days in case 2. The longer interval resulted in better fetal outcome, but it also may have increased the risk to the mother.

We show two cases of embryonal carcinoma and discuss the results treatment in this paper. Although the progress of this malignant tumor after treatment was not related to the stadium of the progress of disease, it was found related to the amount of serum AFP and to the immaturity of this neoplasm. In view of the latent metastasis, the combination chemotherapy with Cisplatin was deemed necessary. The dose intensity must be kept 1. Also, we considered it necessary to prescribe the medicine to the patients more than 6 cycles.

　　A 32-year-old woman underwent the laparoscopic ovarian cystectomy. During the operation, adrenaline was injected into her right ovary, because the amount of bleeding decreased. Soon after the injection, ventricular tachycardia occurred and her blood pressure increased to 190/125. The use of lidocaine induced the electrocardiogram to return to normal and brought down the blood pressure to a normal range. The operation was finished without hitch.　　Vasopressin has both an excellent hemostatic effect and cardiovascular side effects, and is often used at many medical facilities in Japan. But the treatment with vasopressin is neither covered by health insurance nor the relief system for sufferers from adverse drug reactions.　　So we usually use adrenaline which is insurable at laparoscopic operations. Adrenaline has also a hemostatic property, and causes severe cardiovascular adverse events such as ventricular tachycardia when used together with halogenated inhalation anesthetic. The Japanese Society of Anesthesiologists concludes that no serious side effects will arise from using adrenalin and sevoflurane or isoflurane based on its own findings.　　We had a case with ventricular tachycardia which occurred after an adrenaline local injection. But we recommend a careful use of adrenaline for local injection during a laparoscopic operation.

　　We report a case of an epithelioid smooth muscle tumor of low grade malignancy, known as smooth muscle tumor of uncertain malignant potential (STUMP), in a 65-year-old woman. The patient was referred to our hospital because of an abnormal result on screening of the uterus. We initially suspected leiomyosarcoma based on the findings of preoperative medical examinations and tests, so she underwent a total abdominal hysterectomy with salpingo-oophorectomy. The final diagnosis was a tumor with a low malignant potential (STUMP).

Objective: Lymph node recurrence is extremely rare in cases of stage IA1 squamous cell carcinoma (SCC) of the uterine cervix without lymphovascular space invasion (LVSI). We present two cases of extraregional lymph node recurrence after initial surgery for stage IA1 SCC of the uterine cervix without LVSI.Patients: Both patients initially underwent hysterectomy and developed recurrent extraregional lymph nodes within a few years postoperatively.Case 1: The patient showed no symptoms of recurrence, and follow-up computed tomography (CT) for evaluation of gallstones revealed a para-aortic lymph node (9 mm). The patient subsequently underwent serum SCC antigen testing and CT and was diagnosed with recurrence.Case 2: The patient noticed a right inguinal node swelling, which was evaluated using CT. Both patients survived without relapse for 8 and 4 years, respectively.Conclusion: Although stage IA1 SCC of the uterine cervix without LVSI is associated with a low risk of lymph node recurrence, oncologists should consider the possibility of recurrence in such cases. Evaluation for recurrence is difficult in asymptomatic patients. Serum SCC antigen testing may be a useful biochemical marker before imaging for early detection of recurrence, even in asymptomatic patients.
