Early prenatal diagnosis of parapagus conjoined twins.

Conjoined twinning occurs in 1/100 of monozygotic twins, 1/50,000 gestations and 1/250,000 live births. It is the consequence of a division event at the primitive streak stage of the human embryonic development, about 13-14 days after fertilisation, in monochorionic monoamniotic gestations. A healthy pregnant woman, Gravida 2 Para 1, was admitted into our Fetal Medicine Unit to perform the first trimester ultrasound. A diagnosis of conjoined parapagus twinning based on ultrasound features was made at 11 weeks of gestation, and the couple decided to terminate the pregnancy. The ultrasound showed two independent skulls and hearts, a shared spine below the thoracic level, and a shared stomach. The pathological findings were slightly different, showing two independent stomachs draining into a common duodenum. The karyotype was 46 XY. Early prenatal ultrasound may provide a window to counsel the family and to offer an early termination of pregnancy.

Lupus mastitis.

We report a case of a 28-year-old female with the diagnosis of systemic lupus erythematosus (SLE) referred to our breast pathology consultancy in 2002 due to a left breast nodule. Further investigation revealed bilateral coarse calcifications. Biopsy was consistent with a diagnosis of lupus mastitis.

First Trimester Diagnosis of VACTERL Association.

VACTERL association (OMIM 192350) is a non-random combination of multiple congenital malformations including vertebral, anal, cardiac, tracheoesophageal, renal and limb anomalies. The wide spectrum of defects suggests the occurrence of defective development during early embryogenesis. The authors report a case of a complex polymalformative association detected by ultrasound in the first trimester of pregnancy. The ensuing fetal study revealed the presence of vertebral, anorectal, renal and limb anomalies and therefore was considered a case of VACTERL association. This complex association generally entails a poor prognosis. Its early detection allows discussion of management options, including medical termination of pregnancy.

Cervical ectopic pregnancy successfully treated with local methotrexate injection.

OBJECTIVE: To report a case where intra-amniotic injection of methotrexate (MTX) was used to terminate a cervical ectopic pregnancy that was resistant to IM MTX treatment. DESIGN: Case report. PATIENT(S): A 31-year-old woman, gravida 2, para 1, presented with painless vaginal bleeding. An early cervical pregnancy was diagnosed by transvaginal ultrasound. INTERVENTION(S): Intramuscular MTX therapy was started without success, and an intra-amniotic injection of MTX under ultrasonographic guidance was performed. MAIN OUTCOME MEASURE(S): Pregnancy termination. RESULT(S): Pregnancy termination was successful, without complications or side effects. CONCLUSION(S): Local installation of MTX appears to be an effective and safe method; however, choice depends on gestational age, desire to preserve fertility, and, most of all, hemodynamic stability.
