Maternal near-miss (MNM) is a maternal quality care indicator. The World Health Organization (WHO) defines it as a state in which a woman nearly dies but survives due to a complication during pregnancy, birth, or puerperium. The Latin American Federation of Obstetrics and Gynecology (FLASOG) and the Colombian National Health Institute (INS) established recommendations for the event's epidemiological surveillance; nonetheless, the operational definitions of the cases are different. This retrospective study examined the approaches of FLASOG and INS versus the WHO approach (gold standard) for the assessment of MNM in a high obstetric risk unit. Patients admitted with at least one criterion of the WHO, FLASOG, or INS approach for the definition of MNM from March 2016 to March 2017 were included. Sensitivity, specificity, positive and negative predictive value (PPV, NPV) were evaluated, as well as the Receiver Operating Characteristics (ROC) curve of the FLASOG and INS. MNM classification compared to WHO system as reference. The results highlight that the WHO classification establishes very high boundaries for some of the diagnostic criteria and the lack of standardization of the MNM criteria among the different proposals in Latin America hinders the applicability in Colombia and other countries with a similar situation.

Introduction: One of the unexpected side effects of the Haas type palatal expander is ulcers progressing to necrotic lesions in the palatal area due to poor hygiene. The use of antibiotic therapy is mandatory. However, long periods of healing/pain and the need for a systemic host response with the aid of metabolization, especially in children, are issues that should be taken into account in the management of this type of injury. Since phototherapy modalities (antimicrobial photodynamic therapy [aPDT] and photobiomodulation therapy [PBMT]) are able to enhance and accelerate the healing process and reduce the bacterial load, this case report aimed to describe the use of the above-mentioned therapies to treat palatal ulcers occurring during orthodontic expansion. Case Report: The patient, a 10-year-old boy, with a chief complaint of bleeding and continuous pain in the region of his expander was verified on a follow-up visit. After a dental examination, the expander was removed and two necrotic lesions which were in contact with the acrylic part of the tooth-tissue expander were found in the palatal region. The proposal was to use one aPDT session with methylene blue followed by 4 sessions of PBMT with a red laser diode. On the 5th day, reorganized tissue was verified, with the absence of bleeding, swelling, and pain. On the 20th day of follow-up, the area showed no signs of inflammation, healthy tissue without any pathological clinical symptoms, and complete wound healing. Conclusion: The concomitant use of PBMT and aPDT therapies may be considered feasible as an adjunct treatment to manage palatal ulcers resulting from the incorrect use of tooth-tissue types of expanders.

Our group recently analysed a case of MM due to PAS and identified multiple improvement opportunities that depend on the willingness of participants to change the management dynamics of patients with PAS risk factors (Figure 1). We read with great interest the paper by Leitao et al. B 1 b in which it is shown that for every known maternal death, a much greater number of women survive potentially fatal situations and that the associated maternal morbidity may carry with it long-term consequences.

Objective:  To describe the clinical results of patients admitted and managed as cases of placenta accreta spectrum (PAS) at a Central American public hospital and the influence of the prenatal diagnosis on the condition., Materials and Methods:  A retrospective analysis of PAS patients treated at Hospital Bertha Calderón Roque, in Managua, Nicaragua, between June 2017 and September 2021. The diagnostic criteria used were those of the International Federation of Gynecology and Obstetrics (Fédération Internationale de Gynécologie et d'Obstétrique, FIGO, in French). The population was divided into patients with a prenatal ultrasonographic diagnosis of PAS (group 1) and those whose the diagnosis of PAS was established at the time of the caesarean section (group 2)., Results:  During the search, we found 103 cases with a histological and/or clinical diagnosis of PAS; groups 1 and 2 were composed of 51 and 52 patients respectively. Regarding the clinical results of both groups, the patients in group 1 presented a lower frequency of transfusions (56.9% versus 96.1% in group 2), use of a lower number of red blood cell units (RBCUs) among those undergoing transfusions (median: 1; interquartile range: [IQR]: 0-4 versus median: 3; [IQR]: 2-4] in group 2), and lower frequency of 4 or more RBCU transfusions (29.4% versus 46.1% in group 2). Group 1 also exhibited a non-significant trend toward a lower volume of blood loss (1,000 mL [IQR]: 750-2,000 mL versus 1,500 mL [IQR]: 1,200-1,800 mL in group 2), and lower requirement of pelvic packing (1.9% versus 7.7% in group 2)., Conclusion:  Establishing a prenatal diagnosis of PAS is related to a lower frequency of transfusions. We observed a high frequency of prenatal diagnostic failures of PAS. It is a priority to improve prenatal detection of this disease., Competing Interests: The authors have no conflict of interests to declare., (Federação Brasileira de Ginecologia e Obstetrícia.

Objective:  Placenta accreta spectrum (PAS) is a cause of massive obstetric hemorrhage and maternal mortality. The application of family-centered delivery techniques (FCDTs) during surgery to treat this disease is infrequent. We evaluate the implementation of FCDTs during PAS surgeries., Methods:  This was a prospective, descriptive study that included PAS patients undergoing surgical management over a 12-month period. The patients were divided according to whether FCDTs were applied (group 1) or not (group 2), and the clinical outcomes were measured. In addition, hospital anesthesiologists were surveyed to evaluate their opinions regarding the implementation of FCDTs during the surgical management of PAS., Results:  Thirteen patients with PAS were included. The implementation of FCDTs during birth was possible in 53.8% of the patients. The presence of a companion during surgery and skin-to-skin contact did not hinder interdisciplinary management in any case., Conclusion:  Implementation of FCDTs during PAS care is possible in selected patients at centers with experience in managing this disease., Competing Interests: The authors have no conflict of interests to declare., (Federação Brasileira de Ginecologia e Obstetrícia.

Objective:  The immediate referral of patients with risk factors for placenta accreta spectrum (PAS) to specialized centers is recommended, thus favoring an early diagnosis and an interdisciplinary management. However, diagnostic errors are frequent, even in referral centers (RCs). We sought to evaluate the performance of the prenatal diagnosis for PAS in a Latin American hospital., Methods:  A retrospective descriptive study including patients referred due to the suspicion of PAS was conducted. Data from the prenatal imaging studies were compared with the final diagnoses (intraoperative and/or histological)., Results:  A total of 162 patients were included in the present study. The median gestational age at the time of the first PAS suspicious ultrasound was 29 weeks, but patients arrived at the PAS RC at 34 weeks. The frequency of false-positive results at referring hospitals was 68.5%. Sixty-nine patients underwent surgery based on the suspicion of PAS at 35 weeks, and there was a 28.9% false-positive rate at the RC. In 93 patients, the diagnosis of PAS was ruled out at the RC, with a 2.1% false-negative frequency., Conclusion:  The prenatal diagnosis of PAS is better at the RC. However, even in these centers, false-positive results are common; therefore, the intraoperative confirmation of the diagnosis of PAS is essential., Competing Interests: The authors have no conflict of interests to declare., (Federação Brasileira de Ginecologia e Obstetrícia.
