The Relevance of the Second Cesarean Delivery in the Reduction of Institutional Cesarean Delivery Rates.

OBJECTIVE: The cesarean delivery rate has increased worldwide. The aim of our study was to assess the events associated with the second cesarean deliveries in our institution. SUBJECTS AND METHODS: All cesarean deliveries at the Maternity Hospital, Kuwait, from January 1 to December 31, 2013, were identified. A comparative study was undertaken on patients having their first and second cesarean deliveries. The social and clinical characteristics of these patients were extracted from our records and the antenatal, intrapartum, and postpartum course of the pregnancies and their outcomes documented. RESULTS: During the study period, 10,586 deliveries were recorded, including 3,676 cesarean deliveries, i.e., a cesarean delivery rate of 34.7%. 840 of these patients were undergoing their first cesarean delivery (group A) and 607 patients were undergoing their second (group B); 484 patients from group A and 341 patients from group B with complete records were analyzed. Mean age (30.89 ± 4.93 vs. 29.94 ± 5.56 years, p = 0.008), parity (1.49 ± 1.22 vs. 0.98 ± 1.60, p < 0.0001), gestational age at delivery (38.12 ± 2.61 vs. 37.66 ± 3.11 weeks, p = 0.02), and fetal birth weight (3,211.60 ± 691.51 vs. 2,829.73 ± 863.26 g, p < 0.001) were significantly higher in group B than in group A. 53.2% of the patients in group B requested repeat cesarean delivery, their second cesarean. The rate of maternal morbidity was low. CONCLUSIONS: The incidence of repeat cesarean delivery in group B is high, and its reduction should contribute to a lowering of the overall cesarean delivery rate.

Recurrent spontaneous miscarriage is still a challenging diagnostic and therapeutic quagmire.

Recurrent spontaneous miscarriage (RSM), affecting 1-2% of women of reproductive age seeking pregnancy, has been a clinical quagmire and a formidable challenge for the treating physician. There are many areas of controversy in the definition, aetiology, investigations and treatment of RSM. This review will address the many factors involved in the aetiology of RSM which is multifactorial in many patients, with antiphospholipid syndrome (APS) being the most recognized aetiological factor. There is no identifiable cause in about 40-60% of these patients, in which case the condition is classified as idiopathic or unexplained RSM. The RSM investigations are extensive and should be undertaken in dedicated, specialized, well-equipped clinics/centres where services are provided by trained specialists. The challenges faced by the treating physician are even more overwhelming regarding the decision of what should be the most appropriate therapy offered to patients with RSM. Our review will cover the diverse modalities of therapy available including the role of preimplantation genetic testing using recent microarray technology, such as single nucleotide polymorphism and comparative genomic hybridization, as well as preimplantation genetic diagnosis; the greatest emphasis will be on the treatment of APS, and there will be important comments on the management of patients presenting with idiopathic RSM. The controversial areas of the role of natural killer cells in RSM, the varied modalities in the management of idiopathic RSM and the need for better-planned studies will be covered as well.

The reproductive performance of women at 40 years and over.

OBJECTIVE: Adverse pregnancy outcome and increased operative deliveries have been reported in women of advanced maternal age. The objective of our study was to evaluate the reproductive performance of our women 40 years and over, and assess if they were at increased risk for adverse pregnancy outcome compared to younger women. STUDY DESIGN: A retrospective study of all women 40 years and over who delivered singleton pregnancies at Maternity Hospital, Kuwait, from 1 January 2000 through 30 June 2002, was undertaken. One-hundred and sixty-eight women formed the study group while 160 women aged 25-30 years served as the control group. The antenatal records, the intrapartum and postpartum events, and the perinatal outcome were extracted and analysed. Statistical analysis was done by Chi-square test, Fisher exact two-tailed test and the Welch t-test. RESULTS: The mean age of the study and control groups were 41.46+/-1.38 (range 40-47) and 27.40+/-1.67 (range 25-30) years, respectively. The mean parity of the study group, 4.24+/-2.35 was statistically higher than for the control group, 1.69+/-1.39, P < 0.0001. The past history of previous preterm delivery (10.1% versus 4.4%) and previous caesarean section (24.4% versus 11.9%) were more significant in the study group, P = 0.0562 and 0.0053, respectively. Women of 40 years and over presented significantly more medical complications. The incidence of caesarean section in the study group was significantly higher (31.0% versus 16.3%), P = 0.0027, OR 2.310, CI 1.356-3.935. The overall maternal and perinatal outcomes in both groups were comparable and satisfactory. CONCLUSION: Advanced maternal age of 40 years and over was not associated with adverse maternal and perinatal outcome, although the incidence of caesarean section was significantly increased in these women.

Nitric oxide metabolites in preterm and induced labor.

BACKGROUND: Nitric oxide has potent relaxant effects on the pregnant uterus and has been associated with a quiescent uterus in animal and human studies. Nitric oxide donors have been used to arrest preterm labor and a reduction in nitric oxide production has been reported before the onset of labor. OBJECTIVE: The aim of the study was to estimate the serum levels of nitrate and nitrite in women undergoing spontaneous preterm labor and induced labor. MATERIALS AND METHOD: Venous blood was drawn from 39 patients before the onset of labor (control) and also from 17 patients undergoing induction of labor who were in active labor (study group A), and 24 patients in spontaneous preterm labor (study group B). Serum concentrations of nitrate and nitrite were estimated in the samples using the HPLC method. RESULTS: The maternal age of the patients was similar in all the groups. There was no significant difference in the mean gestational age at delivery between the control and group-A patients (38.86 vs. 38.29 weeks); however, there was a significant difference between the control and group-B patients (38.86 vs. 30.92; p < 0.0001), and between study groups A and B (38.29 vs. 30.92 weeks; p < 0.0001). The mean serum levels of nitrite in groups A and B (0.563 +/- 0.15 and 0.512 +/- 0.13, respectively) were significantly lower than the level in the control group (0.915 +/- 0.13; p < 0.0001). Although the serum nitrate levels in study groups A and B were lower than in the control group, this difference was not significant. The maternal outcome was satisfactory but, as expected, the mean birth weight of the babies in group B (1,665.73 +/- 863.84 g) was significantly lower than the birth weights in the control and group-A patients (p < 0.0001). CONCLUSION: There is a drop in nitric oxide production in active preterm labor and induced labor. These findings need to be confirmed in larger studies to establish the role of nitric oxide in the initiation of labor.
