RESUMEN
A 21-year-old first trimester primagravida woman with hyperemesis gravidarum was noted to have incidental subcutaneous emphysema during thyroid ultrasound. Follow-up radiograph demonstrated supraclavicular subcutaneous emphysema, left apical pneumothorax and pneumomediastinum. The patient was transferred to the intensive care unit and evaluated for esophageal rupture. Because no defects were seen on swallow studies/endoscopy and the patient was stable, she was treated conservatively with antibiotics and monitored. The patient's condition improved, and she was discharged on hospital day 6. Subcutaneous emphysema secondary to hyperemesis gravidarum is a rare but potentially life-threatening condition in which the source of the mediastinal leak needs to be immediately determined. After the more serious sources of mediastinal air have been excluded, conservative management is suitable.

Intramural pregnancies are a rare form of ectopic pregnancy located within the myometrium separate from the endometrial cavity. In an effort to prevent potential complications, diagnosis should be made early when more conservative approaches can be performed to preserve reproductive potential. The diagnosis of ectopic pregnancies can be successfully accomplished through sonography; however, intramural pregnancies may be difficult to diagnose as they can appear similar to other etiologies. We present a unique case of a ruptured intramural pregnancy diagnosed with sonography and pelvic MRI in a patient with tuberous sclerosis. Surgical enucleation of the intramural pregnancy was successfully performed with postoperative resolution of beta hCG levels.

We sought to evaluate the likelihood of recurrent diabetes in women with a prior history of diet-treated (class A(1)) gestational diabetes mellitus (GDM). In a retrospective cohort analysis, nulliparous women diagnosed based upon National Diabetes Data Group criteria with diet-treated GDM who had recurrent diabetes in a subsequent pregnancy were compared with those who did not have recurrent diabetes. The probability of recurrent diabetes was calculated using maternal age at first pregnancy, interpregnancy interval, and body mass index (BMI) during the subsequent pregnancy. Three hundred forty-four nulliparous women with diet-treated GDM had a subsequent delivery in our database. One hundred thirty-seven (40%) had recurrent diabetes. Women with a history of GDM were more likely to have recurrent diabetes if they were heavier (193 versus 173 lbs; P < 0.001; BMI 35.7 versus 32.2; P < 0.001) and waited longer between pregnancies (2.9 versus 2.4 years, P = 0.02). Age, interpregnancy interval, and BMI can be used to predict diabetes recurrence in pregnant women with a history of GDM.

OBJECTIVE: The objective of the study was to determine transplacental passage of rosiglitazone (Avandia) using the ex vivo human placental model. STUDY DESIGN: Perfusion studies were performed on 10 placentas from term, uncomplicated deliveries. Concentrations typical for an 8-mg oral dose (216 to 692 ng/mL) as well as 2- to 3-fold increased concentrations were tested (734 to 1261 ng/mL). Transfer of rosiglitazone was assessed and accumulation was determined using the 14C-antipyrine reference method. RESULTS: The clearance index for low and high concentrations were 0.14 +/- 0.04 and 0.20 +/- 0.08, suggesting that the drug passes through the placenta at a relatively low rate. Fetal accumulation occurred in only 1 of 5 placentas at 16.4 ng/mL (5%) for the 8-mg dose and in 2 of 5 placentas ranging from 0 to 74 ng/mL (5% to 8%) at higher concentrations. CONCLUSION: There is minimal transfer and fetal accumulation of rosiglitazone according to the ex vivo human perfusion model.
