Thyroid cancer in pregnancy: a report of 3 cases.

BACKGROUND: Thyroid cancer in pregnancy presents a unique challenge to the thyroid specialist and the obstetrician. We report 3 cases of thyroid cancer diagnosed during pregnancy. CASES: Three cases of papillary thyroid carcinoma were diagnosed during pregnancy, at the 14th, 19th and 40th weeks of gestation. The first 2 cases underwent thyroidectomy immediately after the diagnosis, while in the third the operation was deferred until the postpartum period. All 3 women delivered healthy infants, who were 2 months to 8 years of age at the last follow-up visit. CONCLUSION: If well-differentiated thyroid cancer is diagnosed prior to the midtrimester, it is possible to carry out the surgical intervention in the midtrimester. During late pregnancy, resection after delivery is the option of choice. There is no indication for termination of pregnancy.

Vaginal cuff endometriosis resulting in a fistula between the vagina and abdominal cavity and presenting as peritonitis: a case report.

BACKGROUND: The specimen from a vaginal cuff fistula between the vagina and abdominal cavity revealed endometriosis. Culture of the fluid revealed Streptococcus viridans. CASE: A 44-year-old woman presented with lower abdominal pain for 1 week. She also had cyclic vaginal spotting that had started 1 month after she underwent laparoscopically assisted vaginal hysterectomy for a myoma 2 years earlier. One year prior to this admission, she was noted to have a right endometrioma on a sonographic examination; monthly follow-up revealed that the cyst was enlarging. The patient was admitted for surgery. On laparotomy, severe adhesions were noted. After adhesiolysis, a right adnexal cyst with chocolatelike contents mixed with malodorous, yellowish, mucoid fluid was noted. A vaginal cuff fistula between the vagina and abdominal cavity was also noted. The specimen from this area revealed endometriosis. Culture of the fluid showed Streptococcus viridans. CONCLUSION: Various laparoscopic complications are cited in the literature. Although rare, the risk of infection after laparoscopy can occur. In our case the infection may have been caused by the presence of vaginal cuff fistula in the presence of endometriosis.

A rapidly growing paraurethral myoma with profuse bleeding from a mucosal vessel: report of a case.

Paraurethral leiomyoma is rare. This is the first reported case of a woman with a 6 x 7 x 5 cm urethral leiomyoma with profuse vaginal bleeding. The site of bleeding was identified as the anterior vaginal mucosal vein, which we subsequently electrocauterized. Enucleation of the mass was performed smoothly with a Foley catheter to avoid damage to the urethra. Profuse bleeding from a paraurethral myoma is possibly due to increased vascularity and the prolapsed nature of the tumor in this area.

The correlation between renal function and systolic or diastolic blood pressure in severe preeclamptic women.

OBJECTIVE: To evaluate the correlation between renal function and systolic or diastolic blood pressure in preeclamptic mothers. METHODS: In this prospective study from August 1998 to September 2002, 28 women >or= 28 weeks gestation with severe preeclampsia were selected. Meanwhile, 56 normotensive pregnant women without proteinuria or edema served as the control group. Urine was collected for 24 hours for all subjects. The concentration of uric acid, blood urea nitrogen, creatinine, sodium, calcium, and albumin in the 24-hour urine and blood of both groups were examined. Neonatal outcome also was evaluated. RESULTS: The serum and 24-hour urine concentration of blood urea nitrogen, creatinine, and albumin were significantly higher in severe preeclamptic women. Serum uric acid and urinary albumin/creatinine ratio was significantly higher in severe preeclamptic women compared with that in normotensive mothers and showed positive correlation with systolic or diastolic blood pressure. On the other hand, serum calcium/creatinine ratio was significantly lower in the severe preeclamptic group and negatively correlated to blood pressure. In multiple regressions, systolic or diastolic blood pressure was dependent on serum uric acid, albumin/creatinine, and calcium/creatinine ratios. Fetal birth weight was significantly lower in women with severe preeclampsia and with a lower Apgar score < 7 at 1 minute and 5 minutes and more preterm delivery compared with that in normotensive women. CONCLUSION: Renal function in women with severe preeclampsia was significantly impaired and highly correlated with systolic or diastolic blood pressure.

Short-term postoperative GnRH analogue or danazol treatment after conservative surgery for stage III or IV endometriosis before ovarian stimulation: a prospective, randomized study.

OBJECTIVE: To assess the effect of short-term use of a gonadotropin releasing hormone (GnRH) analogue for 3 months before ovarian stimulation in patients with stage III and IV endometriosis after conservative surgery. STUDY DESIGN: Eleven patients were randomly selected to receive intramuscular injections of GnRH analogue, leuprolide acetate (3.75 mg), every 28 days, or 400 mg danazol orally 2 times per day for 3 months before ovarian stimulation after conservative laparoscopic or laparotomy surgeryfor stage III and IV symptomatic endometriosis (group 1), as compared with 30 patients who had received no postoperative treatment with GnRH analogue or danazol but underwent ovarian stimulation immediately after thefirst menses within 3 months postoperatively (group 2). RESULTS: Although the number of oocytes retrieved and number of embryos per cycle were significantly higher in group 1, the pregnancy rate per cycle in group 1 was not significantly different from that in group 2 (18% vs. 20%). The cumulative pregnancy rate at 12 months was 54.5% and 56.7% in group 1 and group 2, respectively. With regard to recurrence of disease after 24 months of follow-up, group 2 had a statistically significantly higher recurrence rate (13.3%) than did group 1 (0%). CONCLUSION: Short-term use of GnRH analogue before ovarian stimulation in women with stage III or IV endometriosis confers no definite benefits on pregnancy rates per cycle when compared with patients who received ovarian stimulation within 3 months after conservative surgery.

Spontaneous fetal heart rate deceleration: an ominous sign for fetal outcome.

BACKGROUND: The aim of this study was to establish the prognostic import of spontaneous fetal heart-rate deceleration, a sign of fetal distress. METHODS: This retrospective study enrolled 169 patients with fetal heart-rate deceleration treated at Shin-Kong Wu Ho Su Memorial Hospital from 1 January 1998 to 24 November 2000. Reviewed variables included type of fetal heart-rate irregularity (including early, variable, late, and spontaneous variants), neonatal outcome, Doppler results, gestational age and weight at birth, and amniotic fluid index. RESULTS: The spontaneous form of fetal heart-rate deceleration was determined for 11 of the 169 patients (6.5%) diagnosed with fetal heart-rate deceleration, with a 5-min Apgar score below 7 observed for 5 (45.5%) of these subjects, and neonatal complications for 9 (81.8%). Mean gestational age was 32.2+/-3.8 weeks; mean birth weight was 1,560+/-723.9 g. Spontaneous deceleration has a sensitivity of 29%, specificity of 99%, positive predictive value of 81.8%, and negative predictive value of 86.1%. CONCLUSION: Although of the different fetal heart-rate deceleration types the spontaneous variant has the lowest incidence rate, the complication and mortality rates are highest and it is also associated with lower birth weight and higher incidence of pre-term labor. Failure of the fetus to cope with the compromised placental flow and uterine compression resulting from oligohydramnios may be fundamental to the etiology of spontaneous fetal-heart rate deceleration. Once diagnosed, Doppler ultrasound may be used to assess placental-vessel flow. Emergency treatment may be mandatory if deterioration is noted.

Heterotopic triplet pregnancy: report of a case with bilateral tubal pregnancy and an intrauterine pregnancy.

The first report of an ectopic pregnancy following IVF was published in 1976, and since then heterotopic pregnancies (HPs) have been reported at an increasing rate. Although cases of the co-existence of a bilateral tubal and an intrauterine pregnancy following IVF-embryo transfer have been reported, a case of heterotopic triplet pregnancy caused by unilateral tubal embryo transfer has not yet been published in the literature. Here we report on a 38-year-old women (gravida 3, para 1) with a history of infertility who presented to our infertility clinic for evaluation. Hysterosalpingography revealed bilaterally patent Fallopian tubes and stricture of the cervical canal. She conceived after receiving HMG combined with pure FSH, followed by IVF-tubal embryo transfer. Four embryos were replaced into the right tube. Approximately 5 weeks after tubal embryo transfer, the patient presented with lower abdominal tenderness and shock due to internal bleeding. She underwent an emergency laparotomy under the impression of HP. Bilateral tubal pregnancy with right tubal rupture was noted during the operation. The post-operative course was uneventful. Early intervention and thorough inspection of the peritoneal cavity in patients with haemodynamic instability can prevent jeopardizing the life of the mother as well as the ongoing pregnancy.
