A review is given of the various methods of assessing carbohydrate tolerance in pregnancy. Oral glucose tolerance screening and diagnostic tests have been in use for more than 25 years. They are easily administered, relatively inexpensive, and present reasonable sensitivity; therefore, they continue to be used quite extensively. However, lack of reproducibility of the results and side effects such as nausea, vomiting, and headache have led to the use of alternate methods including glucose polymer (Polycose) and standard breakfast meals. These methods have been reported to present satisfactory results in clinical practice. Glycosylated hemoglobin (HbA1c) and fructosamine assays are also alternate forms of testing carbohydrate metabolism HbA1c measurement have been proven insensitive as a screening test for gestational diabetes, while their use as an index of overall glucose control remains valuable. The role of fructosamine in the assessment of carbohydrate intolerance remains controversial with conflicting claims made by various investigators regarding its sensitivity in detecting gestational diabetes and its response to alterations in glycemic control. In this review, the relative advantages and disadvantages of each glucose tolerance test are discussed and recommendations are given regarding their utility in pregnancy.

Polycythemia (venous PCV greater than 65%) in neonates is not an infrequent occurrence. Over the last 2 years out of approximately 1500 admissions to the Neonatal Unit, polycythemia was detected in 46 babies (3.06%). Seventeen (36%) of these babies were preterm and 29 (63%) were term. Approximately one third were small for dates while 2 babies (4%) were large for dates. Four of them had been born to mothers with gestational diabetes and 7 were twin deliveries. Severe perinatal asphyxia (5 minute Apgar score less than or equal to 5) was present in 12 cases (26%). Symptoms suggestive of polycythemia included lethargy in 15%, refusal to feed in 13%, respiratory distress in 10%, vomiting in 8% and abdominal distension in 6%. Associated hypoglycemia was seen in 5 cases (10.8%) while twelve babies (26%) had significant jaundice (bilirubin greater than or equal to 12 mg/dl). Twenty eight babies (60.8%) were given a partial plasma exchange transfusion through the umbilical route. There was 6.5% mortality in these 46 babies with polycythemia. Blood letting through a peripheral vein along with a plasma infusion may be a safer alternative to partial plasma exchange transfusion through umbilical route in babies with polycythemia.

In a population-based case-control study of parous women less than 45 years of age, we evaluated the relations of various pregnancy characteristics to maternal breast cancer risk. Cases (N = 1,239) diagnosed with in situ or invasive breast cancer from 1990 to 1992 in Atlanta, GA, Seattle/Puget Sound, WA, and five counties in central New Jersey, and population controls (N = 1,166) identified by random-digit dialing, were interviewed regarding the details of their pregnancies. We used logistic regression to estimate relative risks (RR) and 95% confidence intervals (CI) and to adjust for breast cancer risk factors. Women who reported nausea or vomiting in their first pregnancy had a slightly lower risk of breast cancer (RR = 0.87; 95% CI = 0.72-1.0). We found no strong or consistent associations for maternal risk related to gestational length, pregnancy weight gain, gestational diabetes, pregnancy hypertension, or gender of the offspring, although we found some evidence for reductions in risk for toxemia (RR = 0.81; 95% CI = 0.61-1.1) and specific sex (RR for female twins vs singletons = 0.48; 95% CI = 0.20-1.3) and timing characteristics of twinning. Overall, these data provide little support for the hypothesis that pregnancy hormone levels are associated with subsequent maternal risk of breast cancer in young women.

A 33-year-old secundipara with a history of gestational diabetes and familial hypertriglyceridemia exacerbated during her previous pregnancy was admitted in the 36th week of gestation with diffuse abdominal pain, vomiting, low-grade fever, and general malaise. A blood sample had a lipemic, milky-pink appearance and plasma concentrations were as follows: triglycerides 2173 mg/dL, cholesterol 320 mg/dL, amylase 801 U/L, lactate dehydrogenase 650 U/L, creatinine 1.5 mg/dL, glucose 380 mg/dL, and left-shifted white cells. Acute pancreatitis was diagnosed and owing to signs of fetal distress, a cesarean was performed under light general anesthesia with propofol, succinylcholine, and sevoflurane. After the umbilical cord was cut, rocoronium and fentanyl were administered. The neonate was healthy and the patient's condition evolved favorably with conservative treatment. The incidence of pancreatitis during pregnancy is low but related morbidity and mortality are high. The usual cause is biliary tract disease, although rare metabolic alterations such as hyperlipidemia may occasionally act as the trigger. Early diagnosis and treatment are the keys to successful surgery and postoperative recovery.

We present an unusual case in which a 23-year-old nulliparous patient was noted to have bilateral multicystic adnexal masses at 21 weeks gestation. Subsequent severe nausea, vomiting, and hyperglycemia with a serum glucose level of 450 mg/dL led to the diagnosis of gestational diabetes. Gradual development of marked maternal virilization ensued and was associated with a serum testosterone level of 4030 ng/mL (free testosterone level of 224 pg/mL), with normal serum dehydroepiandrostendione, estriol, and cortisol levels, leading to the diagnosis of hyperreactio luteinalis. Following vaginal delivery at 38 weeks gestation, gradual and complete spontaneous resolution of signs, symptoms, adnexal masses, diabetes, and testosterone levels were documented.

High utilization of medical services during pregnancy has not been described as most studies have focused on women who receive inadequate or no prenatal care. This paper describes the characteristics and medical utilization data of 500 pregnant women enrolled in a prospective study. High utilizers (HU), who had a mean of 7.8 utilizations (SD = 3.2), were significantly more likely to be nonwhite, low income, and younger than low utilizers (LU) who had a mean of 0.99 utilizations (SD = 1.1). HU reported a 32% rate of recent abuse compared to 9% for LU. HU also reported significantly more stress, lower self-esteem, and more ambivalence about the pregnancy. Consistent with their higher utilization, they were more likely to be diagnosed with preterm labor, hyperemesis, and gestational diabetes. HU had a higher proportion of complaints of nausea, vomiting, diarrhea, and pain and more mental health diagnoses than LU. Overall, HU were a vulnerable group characterized by recent abuse, economic disadvantage, psychosocial stress, and mental health issues. Their high utilization of medical services may have been due in large part to unmet psychosocial needs.

Antepartum pituitary necrosis is a rare medical condition that has only been reported in pregnant women with type I diabetes attributable to diabetes-related vasculopathy and hypercoagulability. We present for the first time a case of antepartum pituitary necrosis occurring in an uncontrolled gestational diabetes mellitus (GDM) patient. The patient was a 32-yr-old woman at 33 weeks and 2 days of gestation. She suffered from severe headache, blurred vision, dizziness, and vomiting. Her baby was delivered by Cesarean section. The brain magnetic resonance images revealed pituitary necrosis. This suggests that pituitary gland necrosis may also complicate GDM pregnancy when glucose levels are uncontrolled.

A 6 yr old pregnant Yorkshire terrier bitch presented 62 days after mating with an acute history of vomiting and coughing. The owners also reported that the dog was polyuric and polydypsic for the last 2 weeks. Complete blood count, serum biochemistry, and urinalysis revealed hyperglycemia, ketonemia, ketonuria, and metabolic acidosis. Diabetic ketoacidosis was diagnosed and after emergency treatment, including fluid therapy, prophylactic antibiotics, and regular insulin, the bitch whelped six healthy normal puppies. Two weeks after treatment, the bitch was clinically normal with normal fructosamine levels. To the authors' knowledge, this is the first reported case of gestational diabetes mellitus in a small breed dog.

Bariatric surgery procedures are more and more performed in women of reproductive age, whose fertility often increases after weight loss, so they frequently become pregnant. In this condition they require appropriate management, according to the type of procedure, malabsorptive or restrictive. If health risks related to obesity (gestational diabetes, pregnancy induced hypertension, pre-eclampsia) decrease after weight loss, other risks related to bariatric procedures could appear. LAGB is a safe and well-tolerated procedure, but some complications could appear more frequently during pregnancy; some symptoms could be suggestive for important complications, that if not treated in the best way could threaten mother and child's health. Emesis of the first trimester could favor slippage, thus influencing feeding and fetal growth. The slippage of the band is a common complication of LAGB, that usually does not lead to serious conditions, but in our case the pregnant risked a lot because of malnutrition. The purpose of this article is to present an obstetric case study of a woman who experienced this complication postbariatric surgery and the implications for mother and child. A correct diagnosis and management of the clinical case led to a positive conclusion, thus underlining bariatric surgery and its complications should be known and taken into account by every physician.

Pregnancy is an insulin resistant state. Hyperglycaemia and gestational diabetes mellitus are well-recognised complications even in women without existing metabolic syndrome or obesity. Pregnant women also appear to be more vulnerable to ketoacidosis, particularly after short periods of reduced oral intake in the third trimester, and may present with very severe starvation ketoacidosis, prompting emergent delivery. We present a case of a woman with a background of depression and psychotic episodes. Olanzapine had been commenced after a psychotic episode at 20 weeks' gestation. Gestational diabetes mellitus was diagnosed at 28 weeks, and she was then admitted at 31 weeks with severe euglycaemic ketoacidosis following a short period of vomiting. She underwent caesarean section when the metabolic disturbances did not resolve with medical treatment. We believe atypical antipsychotic therapy contributed to the profound insulin resistance seen here, and that obstetricians, physicians and psychiatrists must be aware of the risks conferred by these agents in pregnancy.
