Influence of different methods for calculating gestational age at birth on prematurity and small for gestational age proportions: a systematic review with meta-analysis.

BACKGROUND: Recognizing premature newborns and small-for-gestational-age (SGA) is essential for providing care and supporting public policies. This systematic review aims to identify the influence of the last menstrual period (LMP) compared to ultrasonography (USG) before 24 weeks of gestation references on prematurity and SGA proportions at birth. METHODS: Systematic review with meta-analysis followed the recommendations of the PRISMA Statement. PubMed, BVS, LILACS, Scopus-Elsevier, Embase-Elsevier, and Web-of-Science were searched (10-30-2022). The research question was: (P) newborns, (E) USG for estimating GA, (C) LMP for estimating GA, and (O) prematurity and SGA rates for both methods. Independent reviewers screened the articles and extracted the absolute number of preterm and SGA infants, reference standards, design, countries, and bias. Prematurity was birth before 37 weeks of gestation, and SGA was the birth weight below the p10 on the growth curve. The quality of the studies was assessed using the New-Castle-Ottawa Scale. The difference between proportions estimated the size effect in a meta-analysis of prevalence. RESULTS: Among the 642 articles, 20 were included for data extraction and synthesis. The prematurity proportions ranged from 1.8 to 33.6% by USG and varied from 3.4 to 16.5% by the LMP. The pooled risk difference of prematurity proportions revealed an overestimation of the preterm birth of 2% in favor of LMP, with low certainty: 0.02 (95%CI: 0.01 to 0.03); I2 97%). Subgroup analysis of USG biometry (eight articles) showed homogeneity for a null risk difference between prematurity proportions when crown-rump length was the reference: 0.00 (95%CI: -0.001 to 0.000; I2: 0%); for biparietal diameter, risk difference was 0.00 (95%CI: -0.001 to 0.000; I2: 41%). Only one report showed the SGA proportions of 32% by the USG and 38% by the LMP. CONCLUSIONS: LMP-based GA, compared to a USG reference, has little or no effect on prematurity proportions considering the high heterogeneity among studies. Few data (one study) remained unclear the influence of such references on SGA proportions. Results reinforced the importance of qualified GA to mitigate the impact on perinatal statistics.

Mechanical ventilation and death in pregnant patients admitted for COVID-19: a prognostic analysis from the Brazilian COVID-19 registry score.

BACKGROUND: The assessment of clinical prognosis of pregnant COVID-19 patients at hospital presentation is challenging, due to physiological adaptations during pregnancy. Our aim was to assess the performance of the ABC2-SPH score to predict in-hospital mortality and mechanical ventilation support in pregnant patients with COVID-19, to assess the frequency of adverse pregnancy outcomes, and characteristics of pregnant women who died. METHODS: This multicenter cohort included consecutive pregnant patients with COVID-19 admitted to the participating hospitals, from April/2020 to March/2022. Primary outcomes were in-hospital mortality and the composite outcome of mechanical ventilation support and in-hospital mortality. Secondary endpoints were pregnancy outcomes. The overall discrimination of the model was presented as the area under the receiver operating characteristic curve (AUROC). Overall performance was assessed using the Brier score. RESULTS: From 350 pregnant patients (median age 30 [interquartile range (25.2, 35.0)] years-old]), 11.1% had hypertensive disorders, 19.7% required mechanical ventilation support and 6.0% died. The AUROC for in-hospital mortality and for the composite outcome were 0.809 (95% IC: 0.641-0.944) and 0.704 (95% IC: 0.617-0.792), respectively, with good overall performance (Brier = 0.0384 and 0.1610, respectively). Calibration was good for the prediction of in-hospital mortality, but poor for the composite outcome. Women who died had a median age 4 years-old higher, higher frequency of hypertensive disorders (38.1% vs. 9.4%, p < 0.001) and obesity (28.6% vs. 10.6%, p = 0.025) than those who were discharged alive, and their newborns had lower birth weight (2000 vs. 2813, p = 0.001) and five-minute Apgar score (3.0 vs. 8.0, p < 0.001). CONCLUSIONS: The ABC2-SPH score had good overall performance for in-hospital mortality and the composite outcome mechanical ventilation and in-hospital mortality. Calibration was good for the prediction of in-hospital mortality, but it was poor for the composite outcome. Therefore, the score may be useful to predict in-hospital mortality in pregnant patients with COVID-19, in addition to clinical judgment. Newborns from women who died had lower birth weight and Apgar score than those who were discharged alive.

Serum and urine levels of activin A in primigravidae and multigravidae: a prospective cross-sectional study.

The aim of the present study was to investigate serum and urine levels of activin A in different moments of gestation, in primigravidae and in multigravidae, to understand whether these variables (biological sample and first gestation) affect activin A as a biomarker in pregnancy. We prospectively included 43 pairs of serum and urine samples from 25 women examined at different gestational ages (range 45 to 268 days). In the group of primigravidae (n = 16 samples from 9 participants), there was no significant change in serum activin A levels across gestation. Conversely, the group of multigravidae (n = 27 samples from 16 women) had higher serum activin A levels in the third trimester (2676 ± 840 pg/ml) compared to the first (583 ± 408 pg/ml) and second (1040 ± 384) trimesters (p = .025). Urine activin A concentrations did not differ between the two groups and did not change according to the gestation phase. There was no correlation between serum and urinary levels of activin A (r = 0.149, p = .359). These data suggest that activin A secretion may vary less during the first pregnancy, while urine activin A is unlikely to be a surrogate for the systemic levels of this hormone in pregnant women.

Do We Know How to Avoid OASIs in Non-Supine Birth Positions? A Retrospective Cohort Analysis.

OBJECTIVE: To evaluate the association between the upright and supine maternal positions for birth and the incidence of obstetric anal sphincter injuries (OASIs). METHODS: Retrospective cohort study analyzed the data of 1,728 pregnant women who vaginally delivered live single cephalic newborns with a birth weight of 2,500 g. Multiple regression analyses were used to investigate the effect of the supine and upright positions on the incidence of OASIs after adjusting for risk factors and obstetric interventions. RESULTS: In total, 239 (13.8%) births occurred in upright positions, and 1,489 (86.2%) in supine positions. Grade-III lacerations occurred in 43 (2.5%) patients, and grade-IV lacerations occurred in 3 (0.2%) women. Supine positions had a significant protective effect against severe lacerations, odds ratio [95% confidence interval]: 0,47 [0.22-0.99], adjusted for the use of forceps 4.80 [2.15-10.70], nulliparity 2.86 [1.44-5.69], and birth weight 3.30 [1.56-7.00]. Anesthesia (p < 0.070), oxytocin augmentation (p < 0.228), shoulder dystocia (p < 0.670), and episiotomy (p < 0.559) were not associated with the incidence of severe lacerations. CONCLUSION: Upright birth positions were not associated with a lower rate of perineal tears. The interpretation of the findings regarding these positions raised doubts about perineal protection that are still unanswered.

OBJETIVO: Avaliar a associação entre as posições maternas verticais e supinas ao nascimento e a taxa de incidência de lesões obstétricas do esfíncter anal (LOEAs). MéTODOS: Estudo coorte retrospectivo que analisou os dados de 1.728 gestantes que tiveram parto vaginal cefálico simples com peso ao nascer de 2.500 g. Análises de regressão múltipla foram usadas para investigar o efeito de posições supinas ou verticais sobre a taxa de incidência de LOEAs após o ajuste para fatores de risco e intervenções obstétricas. RESULTADOS: No total, 239 (13,8%) nascimentos ocorreram nas posições verticais, e 1,489 (86,2%), nas posições supinas. Lacerações graves de grau III ocorreram em 43 (2,5%) pacientes, e de grau IV, em 3 (0,2%) mulheres. As posições supinas tiveram um efeito protetor significativo contra lacerações graves, razão de probabilidades [Intervalo de Confiança de 95%]: 0,47 [0.22­0.99], ajustado para o uso de Fórceps 4.80 [2.15­10.70], nuliparidade 2.86 [1.44­5.69], e peso ao nascer 3.30 [1.56­7.00]. Anestesia (p < 0.070), aumento de ocitocina (p < 0.228), distocia de ombro (p < 0.670), e episiotomia (p < 0.559) não estiveram associados à incidência de laceração grave. CONCLUSãO: As posições de parto verticais não estiveram associadas a uma menor taxa de ruptura perineal. A interpretação dos achados referentes a essas posições levantou dúvidas sobre a proteção perineal que ainda aguardam respostas.

Detection of cytomegalovirus, herpes virus simplex, and parvovirus b19 in spontaneous abortion placentas.

OBJECTIVE: This study aims to investigate the presence of Cytomegalovirus (CMV), herpes virus simplex (HSV), and parvovirus B19 (PVB19) in the placental tissue of patients who underwent abortions without an otherwise-defined aetiology. STUDY DESIGN: This cross-sectional study was conducted in a high-risk obstetric maternity facility at a University Hospital in Belo Horizonte, Brazil, from January 2013 to December 2015. We included placenta samples obtained from spontaneous abortions of unknown aetiology. Seventy placenta samples were identified and were classified according to histopathological characteristics. All samples were analysed using immunohistochemistry and polymerase chain reaction for CMV, PVB19, and HSV. The clinical variables were collected from the medical records of patients to verify the association of infection with villitis. The patients were divided into the following groups: I) with villitis (n = 28) and II) without villitis (n = 42). METHODS: Immunohistochemistry used monoclonal anti-CMV antibody (NCL-CMVpp65, Leica Biosystems, Wetzlar, Germany), anti-PVB19 antibody (NCL-PARVO, Leica Biosystems, Wetzlar, Germany), and anti-HSV1/HSV2 antibodies (NCL-HSV-1 and HSV2, Leica Biosystems, Wetzlar, Germany). The data were analysed using the Statistical Package for Social Sciences (SPSS Inc, Chicago, IL) 19.0. RESULTS: Viral agents were detected in five patients (7.14%) in the villitis group. Three patients were positive for CMV, one for PVB19, and one for HSV type 2. Foetal and maternal complications were significantly higher in the group with villitis compared with those in the group without villitis (p = .002). CONCLUSIONS: The prevalence of transplacental viral infections as a cause of spontaneous abortion should be considered high in the placenta with villitis. Thus, this study highlights the need for developing diagnostic tests to clarify the aetiology of abortion and foetal loss.

Seventy two-hour glucose monitoring profiles in mild gestational diabetes mellitus: differences from healthy pregnancies and influence of diet counseling.

OBJECTIVE: To study glucose profiles of gestational diabetes (GDM) patients with 72 h of continuous glucose monitoring (CGM) either before (GDM1) or after (GDM2) dietary counseling, comparing them with nondiabetic (NDM) controls. DESIGN AND METHODS: We performed CGM on 22 GDM patients; 11 before and 11 after dietary counseling and compared them to 11 healthy controls. Several physiological and clinical characteristics of the glucose profiles were compared across the groups, including comparisons for pooled 24-h measures and hourly median values, summary measures representing glucose exposure (area under the median curves) and variability (amplitude, standard deviation, interquartile range), and time points related to meals. RESULTS: Most women (81.8%) in the GDM groups had fasting glucose <95mg/dL, suggesting mild GDM. Variability, glucose levels 1 and 2h after breakfast and dinner, peak values after dinner and glucose levels between breakfast and lunch, were all significantly higher in GDM1 than NDM (P<0.05 for all comparisons). The GDM2 results were similar to NDM in all aforementioned comparisons (P>0.05). Both GDM groups spent more time with glucose levels above 140mg/dL when compared with the NDM group. No differences among the groups were found for: pooled measurements and hourly comparisons, exposure, nocturnal, fasting, between lunch and dinner and before meals, as well as after lunch (P>0.05 for all). CONCLUSION: The main differences between the mild GDM1 group and healthy controls were related to glucose variability and excursions above 140mg/dL, while glucose exposure was similar. Glucose levels after breakfast and dinner also discerned the GDM1 group. Dietary counseling was able to keep glucose levels to those of healthy patients.

Surveillance of surgical site infection after cesarean section and time of notification.

BACKGROUND: Cesarean section is a surgical procedure the main complication of which is surgical site infection (SSI), which is related to maternal morbidity and mortality. OBJECTIVE: To evaluate active monitoring by telephone to identify infection and time of SSI report in postpartum women and associated risk factors. METHODS: We conducted a prospective observational study from 2013-2014, at a referral service for high-risk pregnancies. Surveillance was conducted via telephone at least 30 days after cesarean delivery. Incidence ratio and time of infection occurrence (days) was analyzed. Survival analysis was conducted to assess the temporal distribution of the development of infection. RESULTS: Of a total of 353 patients, 14 (4%) cases of SSI were reported, and 10 (7.4%) of the reported cases occurred within 15 days after cesarean and average time of infection was12.21 days. American Society of Anesthesiologists score was the only risk factor associated with SSI after cesarean section. CONCLUSIONS: The prevalence of SSI after cesarean section via telephone is similar to several services with different methods of surveillance, considering it could be used by services with limited resources. Superficial incisional SSI was the most common type of infection, time of infection report was mainly before the 15th day postprocedure, and American Society of Anesthesiologists score of 2 or less was protective against SSI. Telephone calls can be a viable method to identify women with infection briefly after discharge, particularly at-risk patients.

Análise do conteúdo do sumário de alta obstétrica em maternidade de referência. Uma oportunidade para repensar a estratégia da continuidade do cuidado materno e neonatal / Analysis of contents in obstetric discharge summary of a reference maternity. Opportunity to think about the strategy for continuity of maternal and neonatal care

Objetivo: analisar criticamente dados sobre o nascimento e intercorrências clínico-obstétricas dos sumários de alta obstétrica, visando à troca de informações para continuidade do cuidado materno e neonatal. Pacientes e métodos: estudo observacional retrospectivo em base de dados secundários. Foram consultados 102 sumários de alta obstétrica da maternidade do Hospital das Clínicas da UFMG, entre julho e dezembro de 2013. Para se avaliar a pertinência da proposição de um modelo estruturado para o documento eletrônico, as situações de alta obstétrica e os conteúdos clínicos documentados pelos médicos foram comparados entre internações anteparto e pós-parto, empregando-se o teste qui-quadrado de Pearson. Resultados: em 48 (49,5%) dos 97 documentos selecionados, a condição gestacional era de elevado risco. Os campos já estruturados no formulário em uso tiveram alta frequência de preenchimento. Observou-se semelhança entre o conteúdo dos registros clínicos das altas anteparto e pós-parto, a não ser pelos resultadosde exames, mais frequentes no primeiro e pelos dados sobre o nascimento, no segundo. Dados sobre o concepto e orientações para após a alta tiveram frequência aquém do esperado. Conclusões: o sumário de alta obstétrica em um discurso livre sobre os fatos ocorridos durante o nascimento pode falhar em prover dados de qualidade para a continuidadedo cuidado na rede de atenção materno-infantil. Acredita-se que a proposição de um padrão estruturado, contendo um conjunto mínimo de dados possa oferecer subsídios para aprimorar a troca de informações maternas e neonatais.

Objective: to critically analyze data on birth, and clinical and obstetric complications in the content of obstetric discharge reports aiming at exchanging information for the continuity of maternal and neonatal care. Patients and methods: this was a retrospective observational study in a database of secondary data. A total of 102 obstetric discharge reports were consulted from the UFMG General Hospital maternity between July and December of 2013. The obstetric discharge situations and clinical contents documented by physicians were compared between antepartum and postpartum hospitalizations using the chi-square test of Pearson to evaluate the relevance of the proposition of a structuredmodel for electronic documentation. Results: in 48 (49.5%) out of the 97 selected documents, the gestational condition was of high risk. The s already structured in the form in use were filled in high frequency. The similarity between the content of antepartum and postpartum clinical records was observed, except for results of tests, which were morefrequent in the first, and birth data in the second. Data on the newborn and guidance after discharge were often lower than expected. Conclusions:the content in the obstetric discharge report about the events that occurred during birth may fail to provide quality data for the continuity of care in the maternal and child care. It is believed that the proposition of a structured pattern, containing a minimum set of data can provide subsidies to improve the exchange of maternal and neonatal information.

Pregnancy in patients with sickle cell disease: maternal and perinatal outcomes.

OBJECTIVE: To compare obstetrical, hematological and neonatal outcomes of pregnant women with or without sickle cell disease (SCD). METHODS: A prospective study of 60 pregnancies of 58 women with SCD (29 SCD-SS and 29 SCD-SC) compared with 192 pregnancies in 187 healthy pregnant women was carried out from January 2009 to August 2011. RESULTS: Compared to controls, the SCD group had higher rate of preterm delivery (p < 0.001, OR = 4.96, 95% CI 2.57-9.59), higher cesarean rate (p < 0.001, OR = 5.00, CI 2.65-9.45), more frequent deep vein thrombosis (p = 0.003), and urinary infection (p = 0.001, OR = 3.31, CI 1.63-6.73), higher prevalence of small for gestational age babies (p = 0.019, OR = 2.66, CI 1.15-6.17), and more frequent baby admissions to progressive care unit (p < 0.001, OR = 4.89, CI 2.26-10.6). Maternal death rate was also higher among women with SCD (p = 0.056). All adverse events were more frequent in the SS subgroup. Babies from the SS subgroup had the lowest weight at birth (2080 g) compared to SC (2737 g; p < 0.001) and controls (3035 g). A multivariate analysis confirmed painful episodes and SS genotype as factors contributing to preterm delivery. CONCLUSION: SCD pregnant women - especially those in the SS subgroup - are more prone to experience perinatal and maternal complications in comparison with pregnant women without SCD.

Clinical complications in pregnant women with sickle cell disease: prospective study of factors predicting maternal death or near miss

OBJECTIVE: To evaluate complications in pregnant women with sickle cell disease, especially those leading to maternal death or near miss (severe obstetric complications). METHODS: A prospective cohort of 104 pregnant women registered in the Blood Center of Belo Horizonte (Hemominas Foundation) was followed up at high-risk prenatal units. They belonged to Group I (51 hemoglobin SS and three hemoglobin S/ß0-thalassemia) or Group II (49 hemoglobin SC and one hemoglobin S/ß+-thalassemia). Both groups had similar median ages. Predictive factors for 'near miss' or maternal death with p-value = 0.25 in the univariate analysis were included in a multivariate logistic model (significance set for p-value = 0.05). RESULTS: Group I had more frequent episodes of vaso-occlusive crises, more transfusions in the antepartum and postpartum, and higher percentage of preterm deliveries than Group II. Infections and painful crises during the postpartum period were similar in both the groups. The mortality rate was 4.8%: three deaths in Group I and two in Group II. One-third of the women in both the groups experienced near miss. The most frequent event was pneumonia/acute chest syndrome. Alpha-thalassemia co-inheritance and ß-gene haplotypes were not associated with near miss or maternal death. In multivariate analysis predictors of near miss or death were parity above one and baseline red blood cell macrocytosis. In Group I, baseline hypoxemia (saturation < 94%) was also predictive of near miss or death. CONCLUSION: One-third of pregnant women had near miss and 4.8% died. Both hemoglobin SS and SC pregnant women shared the same risk of death or of severe complications, especially pulmonary events...

[Association between risk pregnancy and route of delivery with maternal and neonatal outcomes]. / Associacao entre risco gestacional e tipo de parto com as repercussoes maternas e neonatais.

PURPOSE: To analyze the relationships among gestational risk, type of delivery and immediate maternal and neonatal repercussions. METHODS: A retrospective cohort study based on secondary data was conducted in a university maternity hospital. A total of 1606 births were analyzed over a 9-month period. Epidemiological, clinical, obstetric and neonatal characteristics were compared according to the route of delivery and the gestational risk characterized on the basis of the eligibility criteria for high clinical risk. The occurrence of maternal and neonatal complications during hospitalization was analyzed according to gestational risk and cesarean section delivery using univariate and multivariate logistic analysis. RESULTS: The overall rate of cesarean sections was 38.3%. High gestational risk was present in 50.2% of births, mainly represented by hypertensive disorders and fetal malformations. The total incidence of cesarean section, planned cesarean section or emergency cesarean section was more frequent in pregnant women at gestational high risk (p<0.001). Cesarean section alone did not influence maternal outcome, but was associated with poor neonatal outcome (OR 3.4; 95%CI 2.7-4.4). Gestational high risk was associated with poor maternal and neonatal outcome (OR 3.8; 95%CI 1.3-8.7 and OR 17.5; 95%CI 11.6-26.3, respectively). In multivariate analysis, the ratios were maintained, although the effect of gestational risk has determined a reduction in the OR of the type of delivery alone from 3.4 (95%CI 2.7-4.4) to 1.99 (95%CI 1.5-2.6) for adverse neonatal outcome. CONCLUSION: Gestational risk was the main factor associated with poor maternal and neonatal outcome. Cesarean delivery was not directly associated with poor maternal outcome but increased the chances of unfavorable neonatal outcomes.

Associacao entre risco gestacional e tipo de parto com as repercussoes maternas e neonatais / Association between risk pregnancy and route of delivery with maternal and neonatal outcomes

OBJETIVO: Avaliar as relações entre risco gestacional, tipo de parto e suas repercussões maternas e neonatais imediatas. MÉTODOS: Análise retrospectiva de coorte em base de dados secundários, em maternidade de hospital universitário. Foram considerados 1606 partos no período de nove meses. Características epidemiológicas, clínicas, obstétricas e neonatais foram comparadas em função da via de parto e do risco gestacional, caracterizado conforme os critérios de elegibilidade de alto risco clínico. A ocorrência de complicações maternas e neonatais durante a internação foi analisada em função do risco gestacional e parto cesariano. Para isto, análise logística univariada e multivariada foram empregadas. RESULTADOS: A taxa global de cesarianas foi de 38,3%. O alto risco gestacional esteve presente em 50,2% dos partos, representado principalmente pelos distúrbios hipertensivos e as malformações fetais. A ocorrência total de cesarianas, cesarianas anteparto ou intraparto foi mais frequente em gestantes de elevado risco gestacional (p<0,001]. A cesariana, isoladamente, não influenciou o resultado materno, mas associou-se ao resultado neonatal desfavorável (OR 3,4; IC95% 2,7-4,4). O alto risco gestacional associou-se ao resultado materno e neonatal desfavorável (OR 3,8; IC95% 1,6-8,7 e OR 17,5; IC95% 11,6-26,3, respectivamente) Na análise multivariada, essas relações de risco se mantiveram, embora o efeito do risco gestacional tenha determinado uma redução no OR do tipo de parto isoladamente de 3,4 (IC95% 2,66-4,4) para 1,99 (IC95% 1,5-2,6) para o resultado neonatal desfavorável. CONCLUSÃO: O risco gestacional foi o principal fator associado ao resultado materno e neonatal desfavorável. A cesariana não influenciou diretamente ...

PURPOSE: To analyze the relationships among gestational risk, type of delivery and immediate maternal and neonatal repercussions. METHODS: A retrospective cohort study based on secondary data was conducted in a university maternity hospital. A total of 1606 births were analyzed over a 9-month period. Epidemiological, clinical, obstetric and neonatal characteristics were compared according to the route of delivery and the gestational risk characterized on the basis of the eligibility criteria for high clinical risk. The occurrence of maternal and neonatal complications during hospitalization was analyzed according to gestational risk and cesarean section delivery using univariate and multivariate logistic analysis. RESULTS: The overall rate of cesarean sections was 38.3%. High gestational risk was present in 50.2% of births, mainly represented by hypertensive disorders and fetal malformations. The total incidence of cesarean section, planned cesarean section or emergency cesarean section was more frequent in pregnant women at gestational high risk (p<0.001). Cesarean section alone did not influence maternal outcome, but was associated with poor neonatal outcome (OR 3.4; 95%CI 2.7-4.4). Gestational high risk was associated with poor maternal and neonatal outcome (OR 3.8; 95%CI 1.3-8.7 and OR 17.5; 95%CI 11.6-26.3, respectively). In multivariate analysis, the ratios were maintained, although the effect of gestational risk has determined a reduction in the OR of the type of delivery alone from 3.4 (95%CI 2.7-4.4) to 1.99 (95%CI 1.5-2.6) for adverse neonatal outcome. CONCLUSION: Gestational risk was the main factor associated with poor maternal and neonatal outcome. Cesarean delivery was not directly associated with poor maternal outcome but increased the chances of unfavorable neonatal outcomes. .

Abordagem atual da doença inflamatória pélvica / Current approaches to pelvic inflammatory disease

A doença inflamatória pélvica (DIP) é um processo inflamatório de natureza infecciosa que pode atingir estruturas e órgãos do trato genital superior. Devido à sua importância epidemiológica e de suas graves complicações, este artigo atualiza e propõe uma abordagem sistemática da DIP. Os principais agentes etiológicos são a Neisseria gonorrhoeae,Chlamydia trachomatis e outros agentes etiológicos de uretrites, cervicites, vulvovaginites e vaginoses, em geral, polimicrobiana, o que é a base de sua terapêutica. A mulher deve ser investigada para DIP quando apresenta, especialmente, desconforto abdominal, dor lombar, dispareunia e nódoas ou manchas ao exame ginecológico, previamente a procedimentos transcervicais. A classificação clínico-laparoscópica deDIP pode ser dividida em: a) estágio I (endometrite/salpingite sem peritonite); estágio II (salpingite aguda com peritonite); estágio III (salpingite aguda com oclusão tubária ou abscesso tubo-ovariano); estágio IV (abscesso tubo-ovariano roto). A definição do estágio orienta a conduta e o tratamento, pois em formas leves (estágio I) o tratamento e seguimento podem ser feitos ambulatorialmente, enquanto para os casos moderadosou graves a internação hospitalar está indicada para início do tratamento por via endovenosa e monitorização da resposta ao tratamento. O tratamento suportivo, retirada de dispositivo intrauterino (DIU), abstinência sexual e repouso também são indicados, além de orientações sobre as implicações da doença e abordagem do parceiro.

Pelvic inflammatory disease (PID) is an inflammatory process of infectious nature that can affect structures and organs of the upper genital tract. Considering this disease's epidemiological relevance and severe complications, this article provides an update and proposes a systematic approach to PID. The main etiological agents are Neisseria gonorrhoeae, Chlamydia trachomatis and other etiological agents of urethritis, cervicitis, vulvovaginitis and vaginoses. These are generally of polymicrobial origin, which determines the treatment basis for pelvic inflammatory diseases.Women must be checked for PID when experiencing abdominal discomfort, backache, dyspareunia, or presenting with stains during gynecological examination and prior to transcervical procedures. The clinical and laparoscopic classification of PID can be divided into: a) stage I (endometritis/salpingitis without peritonitis), stage II (acute salpingitis with peritonitis), stage III (acute salpingitis with tubal occlusion or tube-ovarian abscess), and stage IV (tube-ovarian abscess rupture). Defining the stage guides procedures and treatment, given that in mild forms (stage I) the treatment and follow-up can be performed in the ambulatory environment while moderate to severe cases require hospitalization so that intravenous treatment and treatment outcome monitoring can be started. Supportive treatment, removal of intrauterine device (IUD), sexual abstinence and rest are also indicated, as well as counseling on the implications of the disease and partner approach.
