The most serious hazard of gestational diabetes is shoulder dystocia, which sometimes is complicated by Erb's palsy and maternal lacerations. This risk is linked to fetal weight, and is more frequent in cases of diabetes. So, a caesarean section performed when macrosomia is present is required and an induction of labor before severe macrosomia is proposed. Unfortunately, estimation of fetal weight is imprecise in spite of formulas from fetal parameters. Abdomen circumference (AC) alone is as effective as complex formulas. So, it is proposed to perform an elective section when AC is equal or above 38 cm, and to induce labor, after 38 weeks of gestation, for limiting the risk of macrosomia when AC is between 35 and 38 cm. Induction is also proposed when pregnancy is complicated by hypertension or when fetal heart septal hypertrophy occurs. The management of gestational diabetes means a strict control of glycemia, which can reduce macrosomia and the need for cesarean section or induction of labor.

Multiple pregnancies (MP) outcomes are often complicated. They deliver premature infants and provoke high blood pressure. A retrospective study was carried out in 1998 at the Maternity Hospital of Befelatanana, Antananarivo in order to assess MP frequency and to specify the most important favourising factors and difficulties during labor and the quality of the labor management. All pregnancies with a MP were included in this survey. 143 MP were registered: 142 twin pregnancies and 1 triplet pregnancy. 2.0 per cent of cases were recurrent MP. The average age of pregnancies was 26 years old. Among these 143 MP, 48.0 per cent were primiparas. Poor quality of prenatal visits is frequently encountered. As antecedents there are abortion, hormonal contraceptive taking, preterm delivery, gravidic toxemia, cicatricial uterus, ectopic pregnancy. 6.3 per cent of the first twin had breech presentation, 2.0 per cent transversal labor presentation. As events during labor 40.0 per cent dynamic dystocia, 26.0 per cent acute fetal suffering, 27.0 per cent hyperthermia, 23.0 per cent high blood pressure, some of them as eclampsia or pre-eclampsia were noted. 60.0 per cent of the first twin delivery were easy. Whatever his labor presentation, version by internal manipulations following by breech extraction was performed on the second twin (67.0 per cent of cases). 18.2 per cent of parturient women had cesaretomy. 11 maternal deaths were noted. Infant perinatal mortality rate was of 35.7 per cent. Infant morbidity and mortality are essentially due to infections. The authors conclude that complications prevention will be obtained by improvement of standard of living of all female able to procreate. It needs also correct cares at prenatal visits and during labor. Health education must be focalized on strict and correct surveillance of pregnancies and intergenesic periods by the reinforcement of planning family.

Seemingly coincidental occurrence of various pathological conditions may derive from common etiologic denominators. While reviewing 240 malpractice claims involving shoulder dystocia related fetal injuries, we found two antenatal complications in the background conspicuously often. Chronic or pregnancy induced hypertension was identifiable in 80 instances (33%). Pregnancy induced or preexisting diabetes was diagnosed 48 times (20%). Many of these patients were poorly controlled. The blood pressure was usually checked during the antenatal visits. However, about one-half of all patients received no diabetic screening. Therefore, this study may underestimate the actual incidence of diabetes. It has been calculated that the frequency of diabetes in pregnancy and that of hypertension, is about 5% in the United States. Thus, the rates of these complications in this selected group of gravidas was severalfold higher than in the general population. Since hypertension causes retarded fetal growth, it cannot be a direct cause of arrest of the shoulders at delivery. The likely common denominator is maternal diabetes a known predisposing factor both for preeclampsia and shoulder dystocia at birth. In the course of litigations for fetal injuries, demonstration of the predisposing role of seemingly unrelated shortcomings of the medical management may profoundly influence the outcome. This principle is demonstrated by the presentation of an actual malpractice action which resulted in a substantial settlement.

We evaluated the outcome of pregnancies followed between 1990 and 2000 in 93 women with type 1 diabetes, treated with conventional intensive insulin therapy (n=68) or continuous subcutaneous insulin infusion (n=25). We evaluated metabolic control (fasting and 1-hour post-prandial plasma glucose and HbA1c levels), spontaneous or induced abortions, time and mode of delivery, maternal outcome (pregnancy-induced hypertension, preeclampsia, placental insufficiency, hydramnios, hypoglycemic coma, ketoacidosis) and fetal outcome (weight, hypoglycemia, hypocalcemia, hyperbilirubinemia, fetal distress, asphyxia, hyaline membrane disease, polycythemia, shoulder dystocia, malformations). Patients treated with insulin pump more frequently had background retinopathy and clinical neuropathy. No significant differences were observed between the two groups in metabolic control and maternal outcome. Glycemic control, non-optimal in the prepregnancy state, improved significantly during pregnancy, as shown by the progressive reduction in HbA1c levels. As regards fetal outcome, no differences were observed between the two groups in morbidity and especially in malformation rate. Patients with malformed babies did not have optimal metabolic control at conception. Thus, maternal and perinatal outcomes were comparable in patients treated with insulin pump and continuous subcutaneous insulin therapy, and depended on metabolic control. In patients in higher White's class and with more unstable glycemia, we achieved metabolic control and outcomes comparable with those of women of lower White's class and more stable glycemic values using the insulin pump. Our data suggest that insulin pump therapy is useful in problematic, complicated cases of women who want a baby.

The prevalence of obstetric, perinatal and neonatal complications associated with fetal macrosomia at Holberton Hospital in Antigua and Barbuda was assessed by a retrospective, case-control study. All babies of birthweight (BW) greater than 4.5 kg born between July 1991 and January 1997 and all babies with BW greater than 4.0 kg born between July 1991 and January 1995, were included. Control babies, were selected from those born on the same day as the index case. Babies of BW > 4.0 kg and babies of BW > 4.5 kg were 5.7% and 1% of births respectively Records were complete for 157 large babies (40 with BW > 4.5 kg) and 157 control babies < 4.0 kg. Mothers of large babies were significantly older, more parous, more likely to have diabetes mellitus, hypertension, and deliver after 40 weeks gestation. At delivery, mothers of large babies were more likely to bleed. Large babies had lower one minute and five minute Apgar score, were more likely to be meconium stained, have respiratory distress, have birth trauma or dystocia and to be admitted to Special Care Nursery. There was no difference in Caesarean section rate, hospital days, neonatal jaundice or mortality. Babies with BW > 4.5 kg had mortality of 7.5% versus 1.8% for those < 4.5 kg. Fetal macrosomia remains a difficult obstetrical problem associated with significant maternal, perinatal and neonatal consequences. Morbidity and mortality are still significant in developed and developing countries alike.

In a primipara, 28 years of age and with a BMI of 44 kg/m2, a Zavanelli manoeuvre was performed. Due to uterine atony she had to undergo a hysterectomy. A multipara, 39 years of age and with a BMI of 66 kg/m2, experienced that her weight exceeded the limits of the beds and that local anaesthesia was hard to perform; she suffered from a lesion of the lumbosacral plexus caused by a shoulder dystocia. In the end, both mothers and their babies could go home in a moderate condition. Obesity is becoming more prevalent and brings with it an increase in obstetric risks. During pregnancy and delivery, morbidly obese patients should be monitored by a gynaecologist. Special interest should focus on screening for (gestational) diabetes, hypertension and foetal growth. Ultrasound may detect congenital malformations early; however, the sensitivity of ultrasound is lower in morbidly obese patients. When macrosomia is expected, a clear plan should be made regarding the mode of delivery. It is useful to make a treatment protocol for morbidly obese patients.

Obesity is a global health problem that is increasing in prevalence. The World Health Organization characterizes obesity as a pandemic issue, with a higher prevalence in females than males. Thus, many pregnant patients are seen with high body mass index (BMI). Obesity during pregnancy is considered a high-risk state because it is associated with many complications. Compared with normal-weight patients, obese patients have a higher prevalence of infertility. Once they conceive, they have higher rate of early miscarriage and congenital anomalies, including neural tube defects. Besides the coexistence of preexisting diabetes mellitus and chronic hypertension, obese women are more likely to have pregnancy-induced hypertension, gestational diabetes, thromboembolism, macrosomia, and spontaneous intrauterine demises in the latter half of pregnancy. Obese women also require instrument or Cesarean section delivery more often than average-weight women. Following Cesarean section delivery, obese women have a higher incidence of wound infection and disruption. Irrespective of the delivery mode, children born to obese mothers have a higher incidence of macrosomia and associated shoulder dystocia, which can be highly unpredictable. In addition to being large at birth, children born to obese mothers are also more susceptible to obesity in adolescence and adulthood. Prevention is the best way to prevent this problem. As pregnancy is the worst time to lose weight, women with a high BMI should be encouraged to lose weight prior to conceiving. During preconception counseling, they should be educated about the complications associated with high a BMI. Obese women should also be screened for hypertension and diabetes mellitus. In early pregnancy, besides being watchful about the higher association of miscarriage, obese women should be screened with ultrasound for congenital anomalies around 18 to 22 weeks. The ultrasound should be repeated close to term to check on the estimated fetal weight to rule out macrosomia. Obese pregnant women are screened for gestational diabetes around 24 to 28 weeks. During the second half of pregnancy, one needs to closely watch for signs and symptoms of pregnancy-induced hypertension. Once in labor, an early anesthesia consultation is highly recommended irrespective of delivery mode. When Cesarean section is performed, many obstetricians prefer an incision above the pannus to avoid skin infection. However, the incision should be decided upon the discretion of the surgeon. Peripartum, special attention is given to avoid thromboembolism by using compression stockings and early ambulation.

White's classification system (WCS) was created 60 years ago to identify diabetic (DM) pregnancies at increased risk for perinatal morbidity and mortality. Our objective was to assess the association between WCS and adverse pregnancy outcome (APO) in contemporary DM pregnancies. We studied diabetic women with singleton pregnancies who delivered at >20 weeks at a single institution over a 1-year period (2007 to 2008). Perinatal outcomes were compared between WCS groups. APO was defined as any of the following: preterm birth <34 weeks, severe preeclampsia, shoulder dystocia, and neonatal respiratory disease. Presence of vascular disease was defined as presence of chronic hypertension, chronic renal insufficiency, retinopathy, coronary artery disease, or prior cerebrovascular event. One hundred ninety-six DM pregnancies met the criteria. No significant differences in APO existed between White's class groups among women with pregestational DM (32.7% class B versus 26.9% class C versus 57.1% class D to F; p = 0.46). Logistic regression revealed that vascular disease was associated with APO (odds ratio = 2.7, 95% confidence interval = 1.2 to 6.2). In our population, presence of vascular disease, rather than WCS, was a better predictor of APO in DM women.

Obesity is defined as an accumulation of excessive amounts of adipose tissue in the body, and has been called the most common nutritional disease of dogs in Western countries. Most investigators agree that at least 33% of the dogs presented to veterinary clinics are obese, and that the incidence is increasing as human obesity increases in the overall population. Obesity is not just the accumulation of large amounts of adipose tissue, but is associated with important metabolic and hormonal changes in the body, which are the focus of this review. Obesity is associated with a variety of conditions, including osteoarthritis, respiratory distress, glucose intolerance and diabetes mellitus, hypertension, dystocia, decreased heat tolerance, some forms of cancer, and increased risk of anesthetic and surgical complications. Prevention and early recognition of obesity, as well as correcting obesity when it is present, are essential to appropriate health care, and increases both the quality and quantity of life for pets.

Women with gestational diabetes mellitus (GDM) have higher rates of foetal macrosomia, shoulder dystocia and pregnancy-induced hypertension, and are at higher risk of developing type 2 diabetes. Herein, we introduce a new conceptual term, "gestational prediabetes", which requires the absence of diabetes before pregnancy, and the presence of blood glucose levels (or a related marker) in early pregnancy that are higher than normal, but not yet high enough to meet the diagnostic criteria for GDM. Identifying women with gestational prediabetes might be done in early pregnancy (e.g., 12 weeks' gestation) using conventional glycaemic testing, assessment of visceral abdominal adiposity or hepatic fat by ultrasonography, or measuring serum sex hormone-binding globulin or adiponectin. However, none of these approaches has been systematically compared to conventional predictors, such as maternal body mass index or waist circumference. Any early-pregnancy predictor of gestational prediabetes risk needs to have low cost, ease of administration, and a short turnaround time. The theoretical advantage of identifying women with gestational prediabetes would be to "prevent" the onset of GDM (and its inherent risks to the pregnancy) in a timelier manner. One sensible starting point would be an intervention to prevent early excessive weight gain in pregnancy, which is currently being evaluated by two randomized clinical trials. In addition, early intervention could offset the need for resource-intense GDM management or insulin therapy.
