[Vaginal granulocytic sarcoma: CT and MR imaging]. / Vaginales granulozytäres Sarkom: CT und MR Bildgebung.

A 30-year-old female patient with vaginal bleeding was referred to the gynecological unit of our hospital. Speculum examination showed a lobulated tumor, 5 cm in size, at the vaginal fornix. MRI demonstrated a tumor encompassing the ventral part of the vagina and the entire cervix. Computed tomography diagnosed pathologically enlarged mediastinal lymph nodes. Subsequent examinations revealed an acute myeloic leukemia, synchronous histopathological examination of the vaginal tumor led to the rare diagnosis of a granulocytic sarcoma.

[Two-stage delivery after spontaneous rupture of fetal membranes and delayed abortion of the first twin in conservative management]. / Zweizeitige Geburt nach spontanem Blasensprung und Spätabort des ersten Mehrlings bei konservativem Management.

INTRODUCTION: 1-2% of all twin pregnancies are complicated by premature contractions, leading to premature rupture of membranes before 26 weeks of pregnancy. In this situation, a decision is required to either actively induce premature delivery or to initiate expectant management. Maternal and fetal risks regarding perinatal mortality and morbidity and the benefits of pregnancy prolongation have to be weighted against each other. CASE REPORT: We present delayed deliveries of two I-Parae with dichorionic twin pregnancies, achieved by in vitro fertilisation. In both cases, spontaneous membrane rupture and miscarriage of the leading fetus occurred prior to 20 gestational weeks. As signs of infection were missing initially, we adopted a conservative, expectant management. In both cases, the pregnancies could be prolonged to more than 30 weeks' gestation. DISCUSSION: In the absence of additional risk factors, expectant, conservative management of multiple pregnancies after loss of one fetus can lead to pregnancy prolongation of 91 and 96 days, respectively. The gained gestational age of the remaining fetus and the healthy mother-child pairs are discussed under perinatal, economical and psychological aspects.

No benefit from post-caesarean wound drainage.

AIM OF THE STUDY: A prospective randomized controlled trial to determine the benefit of caesarean wound drainage in 305 low-risk pregnant women. METHODS: Pregnant women at low risk of haemorrhage undergoing caesarean section in the Department of Obstetrics, University Hospital, Zurich, between June 1998 and July 1999 were randomised after informed consent into a no-suction group (n = 154) without post-caesarean wound drainage versus a control group with wound drainage (subfascial and subcutaneous) (n = 151). Outcome measures were perioperative decrease in haemoglobin (Hb), postpartum fever (> 38.5 degrees C for > 2 days), sonographic haematoma and other complications requiring revision, cumulative opiate dose adjusted to body weight, length of hospitalisation and operation time. RESULTS: 305 patients completed the study. Decrease in Hb and the rates of fever, haematoma and revision were similar in both groups. However, cumulative opiate dose was lower in the no-suction group (4.5 +/- 1.8 vs 2.8 +/- 1.4 injections, p = 0.0001), and hospital stay was shorter (6.5 +/- 2.4 vs 7.4 +/- 2.8 days, p = 0.0058), as was operation time (32.7 +/- 11.3 v 36.1 +/- 10.5 min; p = 0.0071). CONCLUSIONS: Routine post-caesarean wound drainage is not only useless but cost-ineffective. In the light of our results, wound drainage may be questioned and should be analysed generally.

Ultrafast MR imaging of the pelvic floor.

OBJECTIVE: The aim of this study was to compare pelvic floor anatomy and laxity at rest and on straining (Valsalva's maneuver) using dynamic ultrafast MR imaging in women who were continent versus those with stress incontinence differing in obstetric history. MATERIALS AND METHODS: Thirty continent women were divided into three equal groups (nulliparous, previous cesarean delivery, previous vaginal delivery) and compared with 10 women with stress-incontinence with a history of at least one vaginal delivery. MR imaging of the pelvic floor at rest and on maximal strain was performed, using axial T2-weighted fast spin-echo images followed by sagittal ultrafast T2-weighted single-shot fast spin-echo sequences. Mean population age (age range, 22-45 years; mean +/- SD, 36 +/- 5.4 years), was similar in the four groups, as was parity in the three parous groups. RESULTS: Mean distances between the bladder floor and pubococcygeal line at rest did not differ between the four groups. On straining, bladder floor descent was 1.1 +/- 0.9, 1.0 +/- 1.1, and 1.9 +/- 0.9 cm in continent nulliparous, cesarean delivery, and vaginal delivery women, respectively, versus 3.2 +/- 1.0 cm in incontinent women (p = 0.0005). Cervical descent was greater in incontinent versus nulliparous women (p = 0.0019). Bladder floor descent was greater in the continent vaginal delivery group than in continent cesarean delivery control patients (p = 0.04). In patients with stress incontinence, symptoms did not correlate with amplitude of descent. The right levator muscle was thinner overall than the left, regardless of frequency direction (p = 0.001). CONCLUSION: Ultrafast MR imaging using the T2-weighted single-shot fast spin-echo sequence allows dynamic evaluation of the pelvic compartments at maximal strain with no need for contrast medium. Pelvic floor laxity and supporting fascia abnormalities were most common in patients with stress incontinence followed by continent women with a history of vaginal delivery. The results are therefore compatible with the hypothesis of vaginal delivery as a contributory factor to stress incontinence in older parous women.
