The role of ultrasound-indicated cerclage in triplets.

OBJECTIVES: Preterm delivery is the leading cause of major perinatal morbidity and mortality associated with triplet pregnancies. The objective of this study was to evaluate the efficacy of ultrasound-indicated cervical cerclage in triplet pregnancies that are diagnosed with cervical shortening on biweekly transvaginal sonography (TVS). METHODS: A retrospective review of all triplets who were followed with biweekly TVS for measurement of cervical length was conducted. Cervical shortening was defined as cervical length

The effects of serial intravascular transfusions in ascitic/hydropic RhD-alloimmunized fetuses.

OBJECTIVE: To evaluate the effects of serial intravascular transfusions on RhD-alloimmunized fetuses with ascites/hydrops at the time of the first transfusion by measuring multiple hematological/biochemical blood variables. METHODS: Thirty-one singleton pregnancies were referred for management of RhD alloimmunization. Seven fetuses had hydrops on presentation and were transfused immediately. The remainder underwent weekly ultrasound examinations, and fetal blood sampling and transfusion were performed on development of ascites. In the 104 samples collected overall from the 31 fetuses, glucose, uric acid, urea, creatinine, total protein, total and direct bilirubin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyltransferase, alkaline phosphatase, lactic dehydrogenase, amylase, pseudocholinesterase (PCHE), creatine kinase, triglycerides and cholesterol were measured and compared with a reference range for non-anemic fetuses. RESULTS: The median gestational age at first transfusion was 26 (range, 18-34) weeks. There were three fetal losses after the first transfusion, two of which were due to procedure-related complications; one further loss occurred. At the first transfusion fetal hematocrit, pO2, total protein, PCHE, creatinine and urea concentrations were significantly decreased compared to reference data, while total and direct bilirubin, AST, ALT, amylase, triglyceride and uric acid concentrations were increased. In all surviving fetuses ascites/hydrops had disappeared by the second transfusion. Fetal pO2, total protein, AST, ALT and PCHE concentrations had normalized by the third transfusion. Correction of fetal anemia did not affect the other variables. CONCLUSIONS: RhD-alloimmunized fetuses with ascites/hydrops at the time of the first transfusion had a survival rate of 87%. Alterations of several biochemical fetal blood indices are present at the first sampling/transfusion, but most variables normalize with intravascular transfusions.

On lumping and splitting: a fetus with clinical findings of the oral-facial-digital syndrome type VI, the hydrolethalus syndrome, and the Pallister-Hall syndrome.

The three midline malformation complexes, the oral-facial-digital syndrome type VI (OFDS VI) or Váradi syndrome, the hydrolethalus syndrome (HS), and the Pallister-Hall syndrome (PHS) have been described as distinct genetic entities. Here, we report a fetus with a combination of clinical findings of all 3 syndromes similar to the twin fetuses described in the accompanying paper (Hingorani et al., 1991). The phenotypic overlap in these fetuses with the OFDS VI, HS, and PHS raises the question as to whether or not they indeed represent separate genetic entities as previously assumed.

The use of ritodrine and magnesium sulfate in the arrest of premature labor.

Sixty-seven cases of premature labor (48 with unruptured and 19 with ruptured membranes) were treated with ritodrine or magnesium sulfate infusion supplemented with oral ritodrine in case of initial success. Both treatment regimens were found effective irrespective of maternal age, parity, ethnic background and number of previous abortions. The study supports the clinical experience indicating that early administration of tocolytic agents is highly successful in arresting premature labor and preventing its dire consequences.
