Objectives: To describe the frequency of maternal complications in pregnant women with major or minor placenta previa (PP), and to assess a potential association between PP type and the presence of severe maternal bleeding and other associated outcomes.

Materials and methods: Retrospective descriptive cohort. The study included pregnant women with 20 weeks of gestation or more and a confirmed diagnosis of placenta previa who were seen in a high complexity hospital in Cali (Colombia), between January 2011 and December 2020. Women with a diagnosis of placenta previa and concomitant placenta accreta were excluded. The collected variables were maternal age, body mass index, smoking, obesity, parity, presence of bleeding, postpartum hemorrhage, management of postpartum hemorrhage, transfusion, and maternal ICU admission. A descriptive analysis was performed. The protocol was approved by the ethics committee of Fundaciónn Valle de Lili.

Results: A total of 146 patients met the inclusion criteria. The population consisted of women with a mean age of 32 years, with no history of prior surgery, with a prenatal diagnosis of placente previa at week 22; 70 % were major placenta previa cases. The most frequent complications were postpartum hemorrhage (37.9 % vs. 16.3 % for patients with major and minor placenta previa, respectively), transfusion requirement (23.3 and 9.3 %, respectively), and maternal ICU admission (40.8 % vs. 18.6 %, respectively). There were no cases of maternal death.

Conclusions: There is a high frequency of complications in women with placenta previa, and it is probably higher in cases of major placenta previa. Further studies are needed to compare the frequency of maternal complications according to the type of placenta previa.

Objectives: To report the case of a pregnant woman with prenatal diagnosis of fetal immature nasopharyngeal teratoma, and to conduct a review of the literature describing the prognosis of this condition.

Materials and methods: We report the case of a 27-year-old pregnant woman who received care at the Obstetrics and Gynecology Unit of a reference hospital in Bogotá (Colombia) because of a finding during a prenatal visit of evidence of polyhydramnios, secondary to a nasopharyngeal teratoma. A literature search was conducted in the Medline vía PubMed, Scopus, SciELO and ScienceDirect databases, restricted by language (English and Spanish) and date of publication (January 2001 to January 2021). Case reports and case series covering the prognosis of this condition were included.

Results: Overall, 168 titles were retrieved, 55 of which met the inclusion criteria. Perinatal outcomes for a total of 58 fetuses with a diagnosis of immature nasopharyngeal teratoma detected during the prenatal stage were reported. In the identified cases, perinatal mortality was 25.4 % and the percentage of fetal demise was close to 3.6 %.

Conclusions: Immature nasopharyngeal teratoma is an infrequent condition. The available literature suggests that fetal prognosis depends on the degree of compromise of intracranial structures and the possibility of resecting the lesion. Further studies are needed to assess the prognosis of fetuses with immature nasopharyngeal teratoma.

Objectives: To describe how the frequency of cesarean section has evolved in Colombia since 1998, both in overall terms as well as discriminated according to the legal standing of the healthcare providers (IPSs) where delivery takes place, and to estimate the size of the association between the legal standing of the institutions and the performance of cesarean sections between 2015 and 2017.

Material and methods: A cross-sectional cohort study that describes the frequency of cesarean deliveries between 1998 and 2020, plus an analytical component to estimate the association between the legal nature and the route of delivery between 2015 and 2017, based on the birth records of the Colombian National Statistics Administrative Department (DANE). The prevalence ratio was used as an estimator of this association.

Results: In 1998, the proportion of cesarean deliveries was 25.7 %; it increased to 46.4 % by 2015 and then dropped to 44.6 % by 2020. After 1998, the proportion of cesarean sections in public hospitals increased from 26.2 % to 42.9 % by 2014, while in private providers it increased from 45.0 % to 57.7 % by 2013. The prevalence ratio of cesarean sections in private versus public institutions was 1.57 (95 % CI: 1.56-1.57).

Conclusions: After a long period of sustained growth, there is now a reduction in the proportion of cesarean sections in the country. In public health care institutions, these procedures increased in greater proportion during most of the study period, while in private healthcare providers they are carried out at a higher frequency in all subgroups of women. It will be necessary to evaluate in the future, using more robust methodologies, whether the decrease in the frequency of cesarean section is a real or secular trend.

Objectives: To assess the frequency of instrumented delivery in Colombia and by regions between 2015 and 2019.

Materials and methods: Cross-sectional study based on population registries. Records of women with a gestational age of more than 28 weeks and vaginal delivery were included. Consecutive sampling was used. The information was taken from live birth certificates of the National Administrative Department of Statistics (DANE). Sociodemographic and clinical variables were described. The frequency of instrumented deliveries was calculated and described by year and by department.

Results: Overall, 3,224,218 live birth records were included. Of these 1,719,405 (53.33 %) were vaginal deliveries and 1,468,726 (45.55 %) were cesarean births. At a national level, the frequency of instrumented deliveries between 2015 and 2019 was 36,087 births (1.11 %); Antioquia and Bogotá, D.C. were the places with the highest occurrence, with 16,201 (4.5 %) and 13,686 (2.52 %), respectively.

Conclusions: The occurrence of instrumented vaginal delivery in Colombia is the lowest and tends to diminish. Training of healthcare professionals in this approach during labor must not be abandoned, particularly in Obstetrics and Gynecology training programs. Further studies should be conducted to determine whether the increased adequate use of this technique could contribute to a lower rate of cesarean sections, and also to describe the clinical setting in which its use is safe for both the mother and the fetus. Prospective studies are required to identify the causes leading to the lower use of this obstetric tool as well as the risks and benefits in terms of maternal and perinatal outcomes.
