Twin pregnancy is increasing as infertility treatment is widely given nowadays using assisted reproductive technologies. Twin pregnancy is a risk factor for some complicated pregnancies and it may also cause a hard labor. Although cesarean delivery is frequently indicated in many hospitals in Japan for twin pregnancy in view of the risk of vaginal delivery of the second baby, we have tried vaginal delivery of twin pregnancy in a certain situation. We studied the methods of twin delivery, its outcomes and the early neonatal condition.
  We found 251 twin deliveries (4.6%) in a total of 5,464 deliveries after 22 weeks of pregnancy from January 2005 to December 2009 in the delivery record. Forty-six percent of women pregnant with twins delivered their babies after 33-36 weeks of pregnancy and 41% after 37 weeks of pregnancy. Sixty-five percent delivered by Cesarean section, 33% by vaginal delivery, and 2% vaginally for the first baby and by Cesarean section for the second baby. Fifty percent of the Cesarean deliveries were performed as patients so desired. Ninety women pregnant with twins chose vaginal delivery in which 92% (64/69) of vertex/vertex presentation and 86% (18/21) of vertex/ breech presentation succeeded in vaginal delivery. Neonatal outcome was assessed in 90 vaginally deliveried babies by use of the Apgar scoring system. One-minute Apgar scores of 0-3 (severe asphyxia) were given to 4.5% (8/180) of babies and scores of 4-6 (moderate asphyxia) to 3.3% (6/180) of babies. The incidence meant that a mother had 8.9% and 6.7% of high risk of severe and moderate asphyxia of her babies. But severe asphyxia decreased to 1.7% (3/180), moderate asphyxia to 1.1% (2/180) of babies on the assessment of 5-minute Apgar scores that reflected long-term neonatal outcome. Eleven cases were second babies of all 14 cases of asphyxia on the assessment of 1-minute Apgar scores. In the vaginal delivery group, 5 cases of umbilical cord prolapsed and 3 cases of placental abruption occurred in second babies. In conclusion, twin delivery should be attempted at the birth center where neonatologists and anesthesiologists are available 24 hours as extra-emergency Cesarean delivery can be performed because of the high incidence of emergency Cesarean delivery of second baby (5.6%) and asphyxia of neonates delivered vaginally.

  A 41-year-old woman, gravid 3, para 3, was admitted to the Department of Obstetrics and Gynecology at Tsuchiura Kyodo General Hospital, complaining of a tender, gradually enlarging mass in the right inguinal region during menses. Examination found the mass was about 2 cm in diameter, which protruded slightly (on lying position?). During menstrual periods, the mass enlarged and the pain intensified, but between menses, the mass decreased in size and the pain subsided. The case was diagnosed as inguinal endometriosis and then a preoperative GnRH analog therapy was given for six weeks to make a good operative local condition. Surgery was performed under general anesthesia and a mass about 4.0×3.0 cm in diameter near inguinal ligament was removed. The cut surface revealed small hemorrhagic areas or spaces. Microscopic examination of the dissected mass confirmed the diagnosis of inguinal endometriosis. It was found that the patient had a moderate inguinal swelling on the first visit to the hospital as an outpatient 7 days after operation, but the swelling disappeared shortly afterword. She has been receiving a post-operative GnRH analog therapy for 3 months to maintain a good local condition. The authors concluded thatthe appearance of a lump in the inguinal region and objective changes of the lesion in relation to the menstrual cycle should be considered as the symptoms of endometriosis.

  We report a case of new-onset depressive disorder in a patient with a history of rectal endometriosis treated with GnRH analog and no previous psychiatric history. This medical history allowed us to suspect the possibility of a link between GnRH analog and depression. It also highlighted the need to screen patients treated with GnRH analog for depression.
  The patient was 41-year-old woman who had been diagnosed with rectal endometriosis. She was referred to the Gynecology Department of Tsuchiura Kyodo General Hospital. The subjective symptoms included cyclic abdominal pains and rectal bleedings. The patient had undergone total abdominal hysterectomy and left salpingo-oophorectomy for endometriosis two years before. She was started by her first gynecologist on GnRH agonist (nafarelin acetate) and the symptoms disappeared soon. But several weeks after the initiation of the GnRH agonist treatment, she began to feel depressed and hopeless. She visited a psychiatric hospital and diagnosed as having depression. She was given anti-depressive drugs and inpatient treatment at the psychiatric hospital. Her clinical course was reviewed by her second gynecologist, and she was suspected to have developed depressive disorder by GnRH analog treatment. She stopped taking GnRH analog medication and started progestin (Dinagest) therapy. She became soon free of depressive disorder and then anti-depressive drugs with rectal endometriosis well controlled. This case also suggested Dinagest is a recommended drug for rectal endometriosis.
