Abstract
OBJECTIVES To describe changes in umbilical artery (UA) Doppler flow in monochorionic diamniotic (MCDA) twins affected by selective intrauterine growth restriction (sIUGR), to correlate Doppler findings with pregnancy course and perinatal outcome, and to report postnatal follow-up. METHODS This was a retrospective study of 140 MCDA twins with sIUGR. UA end-diastolic flow, defined as Doppler waveform pattern Type I (persistently positive), Type II (persistently absent or persistently reversed) or Type III (intermittently absent or intermittently reversed), was recorded at first examination and monitored weekly until double or single intrauterine fetal death (IUFD), bipolar cord coagulation or delivery. All neonates had an early neonatal brain scan, magnetic resonance imaging, when indicated, and neurological assessment during infancy. Rates (per 100 person-weeks) and hazard ratios (HR) of IUFD in the IUGR twin in each pregnancy were calculated considering UA Doppler pattern as a time-dependent variable. RESULTS At first examination, there were 65 cases with UA Doppler waveform pattern Type I, 62 with Type II and 13 with Type III. Of the 65 Type-I cases, 48 (74%) remained stable, while 17 (26%) changed to either Type II absent (14%), Type II reversed (9%) or Type III (3%). Of 62 Type-II cases (47 with absent and 15 with reversed flow), 33 (53%) remained stable (18 with absent and all 15 with reversed flow). The 29 Type-II absent cases which changed became Type II reversed (24/47, 51%) or Type III (5/47, 11%). All 13 Type-III cases remained stable. Compared with Type I, the risk of IUFD (adjusted for estimated fetal weight discordance and amniotic fluid deepest vertical pocket) was highest when the pregnancy was or became Type II reversed (HR, 9.5; 95% CI, 2.7-32.7) or Type II absent (HR, 4.3; 95% CI, 1.3-14.3). Mild neurological impairment was more prevalent in the IUGR twin than in the large cotwin (7% vs 1%, P = 0.02). CONCLUSIONS Risk stratification based on UA Doppler is useful for planning ultrasound surveillance. However, patterns can change over time, with important consequences for management and outcome.

Abstract
OBJECTIVE To review the experience of performing selective feticide with bipolar cord coagulation (BCC) in complicated monochorionic (MC) twin pregnancies at a single center. METHODS This was a retrospective analysis of BCC performed using 3-mm bipolar forceps under ultrasound control in cases complicated by twin-to-twin transfusion syndrome, selective growth restriction, discordant anomaly or twin reversed arterial perfusion sequence. RESULTS The series comprised 118 cases with a median gestational age at the time of the procedure of 22 (range, 16-30) weeks. There were 14 (12%) intrauterine deaths of the cotwin, eight (7%) miscarriages and one (1%) termination of pregnancy. When BCC was performed before 19 weeks of gestation, the rate of miscarriage was 45%, whereas it was 3% (P < 0.001) when BCC was performed after 19 weeks. Preterm prelabor rupture of membranes (PPROM) occurred in 45 (38%) cases. The median interval between BCC and PPROM was 4 (interquartile range, 2-9) weeks. In 15 (13%) cases, PPROM occurred within 2 weeks after the procedure. Median gestational age at delivery was 34 (range, 24-41) weeks. The median birth weight was 2103 (range, 480-3875) g. Neonatal death occurred in 11 (9%) cases, and two (2%) children had severe neurologic morbidity. The overall survival rate was 71% (84/118). CONCLUSION BCC is an effective procedure in complicated MC twin pregnancies for selective feticide or when one fetus is severely jeopardized and delivery is not yet an option. Better outcomes can be achieved when this procedure is performed after 19 weeks.

Abstract
OBJECTIVE To report the incidence of fetal and maternal complications after selective fetoscopic laser surgery for twin-to-twin transfusion syndrome (TTTS). METHODS A total of 150 cases of TTTS were treated from January 2004 to June 2009 (period 1, 2004-2006, 62 cases; period 2, 2007 to June 2009, 88 cases). Fetal complications (double and single intrauterine fetal death, recurrence of TTTS, twin anemia-polycythemia sequence (TAPS), reversal of TTTS, cerebral lesions in one twin) and maternal complications were recorded, and retrospectively analyzed. RESULTS Nineteen (12.6%), 58 (38.7%), 61 (40.7%) and 12 cases (8.0%) were classified preoperatively as Quintero stage I, II, III and IV, respectively. The anterior placenta was described in 73 cases (48.6%). Double and single fetal death occurred overall in 7.3 and 36.0% of cases, respectively. The rate of recurrence was 11.3%, of TAPS 3.3%, and of reversal of TTTS 1.3%. Cerebral lesions were diagnosed in 3 donors (2.0%). Eighteen cases (12.0%) of fetal complications had a second procedure (6 repeat laser, 4 serial amnioreduction, 8 bipolar cord coagulation). Pregnancies undergoing a second procedure delivered at a median gestational age of 30.2 weeks compared to 32.1 weeks for those not repeating (p = 0.04). Perinatal survival of at least one twin improved from 66.1 to 79.5% (p = 0.06) in the two consecutive periods. For every 10 laser surgeries performed, there was an average improvement of 1.5% in the predicted percentage of survival of at least one twin (OR 1.09, 95% CI 1.00-1.19). Major maternal complications occurred in 9 cases (6.0%), 3 of which required admission to intensive care unit. CONCLUSIONS Fetal complications are common after fetoscopic laser surgery. In this experience, an increasing number of procedures improved the performance of a new fetoscopic laser center.

Abstract
OBJECTIVE This prospective randomized trial compares the effects of a 5% glucose solution or no infusion during labor on glucose levels, pH, pO2, pCO2, and base excess (BE) of normal pregnant women in early labor and at delivery, and on fetal cord blood. METHODS Forty-three women were randomized to glucose infusion and 38 were controls. RESULTS Starting glucose levels were independent from the fasting state. When no glucose supplementation was given, the labor itself was associated with a reduction of mean pH (from 7.42 to 7.36, P = 0.00001), mean pCO2 (from 25.7 to 24.4 mm Hg, P = 0.04), and mean BE (from -6.3 to -9.8 mEq/L, P = 0.00001), and an increase of capillary glucose (from a mean of 83 to 105 mg/dL, P = 0.00001). Infusions of glucose did not significantly alter maternal acid-base balance at delivery. pH, PO2, pCO2, and BE were similar in arterial and venous cord blood of both groups. No variables correlated with cord blood glucose levels or with glucose vein-artery difference. CONCLUSIONS We conclude that a 5% glucose infusion does not significantly reduce maternal acidemia associated with vaginal delivery and therefore its use cannot be recommended, since maternal glucose is largely available during labor. Intrapartum glucose infusions do not alter the acid-base balance, when the fetus is well oxygenated.

Abstract
Having observed a patient presenting micropolyarteritis with necrotic skin lesions, hypertension and renal injury, the authors had the opportunity to define more closely a disease that only recently has been recognized as a separate nosological entity within the vast and as yet not fully understood field of arterial disorders. In addition, recent literature on the subject is critically reviewed.
