Efecto del implante anticonceptivo sub-dérmico de Etonogestrel sobre el peso corporal en mujeres en edad reproductiva

Objetivo: Analizar el efecto sobre el peso corporal de la anticoncepción hormonal continua mediante implante sub-dérmico liberador de etonogestrel (ENG) en mujeres en edad reproductiva atendidas en la consulta de planificación familiar de un hospital venezolano. Métodos: Investigación comparativa, con diseño cuasi experimental, de casos y controles, a etiqueta abierta, y prospectivo; con una muestra intencionada de 60 mujeres separadas para recibir bien sea un implante subdérmico (Implanon NXT®; casos) o un dispositivo intrauterino (DIU) de cobre (T de cobre; controles). Se evaluaron el peso corporal e índice de masa corporal antes y posterior de doce meses del uso del contraceptivo; así como las características demográficas de las usuarias, efectos adversos y efectividad anticonceptiva de cada método. Resultados: Luego de un año con el implante de ENG no se encontraron variaciones significativas respecto a las mediciones iniciales del peso corporal (61,21±8,30 vs. 61,23±9,50, p>0,5) e IMC (25,23±3.89 vs. 25,26 ±4,30; p>0,05); contrariamente, a lo observado entre las usuarias del DIU donde tanto el peso corporal como el IMC tuvieron un aumento significativo (P<0,05). Asimismo, la mayoría de las usuarias se mantuvieron en el mismo rango de peso donde se encontraban al iniciar el método (p<0,001); mientras que la ganancia ponderal fue mayor entre las usuarias del DIU (1,530±2,04 vs. 3,700±3,02; p<0,05). Conclusiones: El implante de ENG no produce aumento del peso corporal luego de 12 meses de uso, con mínimos efectos adversos y alta efectividad contraceptiva.

Aim: To analyse the effect on body weight of continuous hormonal contraception by releasing subdermal implant etonogestrel (ENG) in women of reproductive age treated in the family planning consultation of a Venezuelan hospital. Methods: Comparative and applied research, with quasiexperimental, case-control, open label and prospective design, with an intentional sample of 60 women separated to receive the contraceptive implant (Implanon NXT®; cases) or a cooper intrauterine device (IUD) (Cooper T; controls) was carried out. Body weight and body mass index were evaluated before and after 12 months of contraceptive use; as well as demographic characteristics of users, side effects, and contraceptive effectiveness of each method. Results: After one year with the ENG implant, no significant variations were found with respect to initial measurements of body weight (61.21±8.30 vs. 61.23±9.50, p>0.5) and BMI (25.23±3.89 vs 25.26±4.30; p>0.05); on the contrary, to what was observed among IUD users where both body weight and BMI had a significant increase (P<0.05). Likewise, most users remained in the same weight range as when starting the method (p<0.001); while weight gain was greater among IUD users (1,530±2.04 vs. 3,700±3.02; p<0.05). Conclusions: The ENG implant does not produce an increase in body weight after 12 months of use, with minimal adverse effects and high contraceptive efficacy.

O uso de métodos contraceptivos hormonais em pacientes com asma: repercussões clínicas / The use of hormonal contraceptives methods in patients with asthma: clinical repercussions

Objetivo: Analisar o uso dos contraceptivos hormonais em mulheres com asma e a escolha desses métodos contraceptivos para essa população, com avaliação de eventuais repercussões sobre novos episódios de asma e sibilos. Métodos: Foram selecionados estudos longitudinais, ensaios clínicos, revisões sistemáticas e metanálises. As plataformas consultadas foram PubMed, Embase, Cochrane e SciELO, com a utilização dos descritores: "contracepção", "contracepção hormonal", "sistema intrauterino liberador de levonorgestrel" e "asma". Resultados: Dois grandes estudos demonstraram que o uso de contraceptivos hormonais esteve associado à redução do risco de novos episódios de asma. Uma revisão sistemática concluiu que os resultados para o uso de contraceptivos hormonais para mulheres com asma foram mistos, com aumento ou redução dos seguintes riscos: novo episódio de asma e aumento da frequência das crises e dos sibilos. O uso da contracepção hormonal em pacientes obesas portadoras de asma é controverso. Conclusão: Os resultados para o uso de contraceptivos hormonais em mulheres com asma são inconsistentes, com relatos de aumento ou de redução do risco de novos episódios. O uso do método contraceptivo deve ser discutido individualmente, levando-se em consideração outros fatores de risco associados e o desejo da mulher. A paciente deverá ser orientada se houver piora dos sintomas clínicos de asma na vigência do uso de qualquer método contraceptivo hormonal.

Objective: To analyze the use of hormonal contraceptives in women with asthma and the choice of this contraceptive method for this population, evaluating possible repercussions on new episodes of asthma and wheezing. Methods: Longitudinal studies, clinical trials, systematic reviews and meta-analyses were selected. Platforms consulted: PubMed, Embase, Cochrane, SciELO, using the descriptors: "contraception", "hormonal contraception", "levonorgestrel-releasing intrauterine system" and "asthma". Results: Two large studies demonstrated that the use of hormonal contraceptives was associated with a reduced risk of new episodes of asthma. A systematic review concluded that the results for the use of hormonal contraceptives for women with asthma were mixed, with increased or decrease in the following risks: new asthma episodes, increased frequency and wheezing. The use of hormonal contraception in obese patients with asthma is controversial. Conclusion: The results for the use of hormonal contraceptives in women with asthma are inconsistent, with reports of increased or reduced risk of new episodes. The use of the contraceptive method should be discussed individually, taking into account other associated risk factors and the woman's desire. The patient will be advised if there is a worsening of the clinical symptoms of asthma while using any hormonal contraceptive method.

Effect of the timing of insertion of postpartum intrauterine contraceptive device (PPIUCD) copper T380A on expulsion rates

Background & objectives: Postpartum intrauterine contraceptive device (PPIUCD) is well accepted and recommended for contraception. However, anxiety at the time of delivery may restrict the acceptance of a PPIUCD for its immediate insertion. So far there is limited evidence to conclude anything concrete on the association between the expulsion rates and the timing of insertion following a vaginal delivery. Thus, this study was undertaken to compare the expulsion rates in immediate and early insertions and their safety and complications. Methods: This prospective comparative study was carried out over 17 months on women delivering vaginally in a tertiary care teaching hospital in South India. A copper device (CuT380A) was inserted using Kelly’s placental forceps either within 10 min of placental delivery (immediate group, n=160) or between 10 min upto 48 h postpartum (early group, n=160). Ultrasound was done before discharge from the hospital. The expulsion rates and any other complications at six-week and three-month follow up were studied. Chi-square test was used to compare the difference in expulsion rates. Results: The expulsion rate was five per cent in the immediate compared to 3.7 per cent in the early group (no significant difference). In ten cases, the device was found to be in the lower uterus upon ultrasound before discharge. These were repositioned. There was no case with perforation, irregular bleeding or infection up to the three-month follow up. Higher age, higher parity, lack of satisfaction and motivation to continue were predictors of expulsion. Interpretation & conclusions: In the present study PPIUCD was found to be safe with overall expulsion in 4.3 per cent. It was marginally, though not significantly, higher in the immediate group.

Meta analysis of the efficacy of three kinds of uterine barriers in preventing re-adhesion after separation of moderate or severe intrauterine adhesion / 中国医师进修杂志

Objective:To evaluate the efficacy of three kinds of uterine barriers: cook balloon, Foley balloon and intrauterine devices in preventing re-adhesion after separation of moderate or severe intrauterine adhesions.Methods:Seven databases including PubMed, Embase, Medline, Cochrane Library, China HowNet, Wanfang and CQVIP were used to retrieve, and the randomized controlled trials on the effect of using COOK balloon, Foley balloon and intrauterine devices to prevent re-adhesion after the separation of moderate and severe intrauterine adhesions were collected from the establishment of the database to December 2021. Revman 5.1 software was used for Meta analysis.Results:A total of 16 articles were selected according to the inclusion criteria. Meta analysis results showed that the rates of preventing postoperative re-adhesion, improving menstruation and pregnancy in COOK balloon were significantly better than those in intrauterine devices ( OR = 0.31, 2.75 and 1.58; 95% CI 0.19 to 0.49, 1.74 to 4.35 and 1.07 to 2.34; P<0.01); the rates of preventing postoperative re-adhesion, improving menstruation and pregnancy in Foley balloon were significantly better than those in intrauterine devices ( OR = 0.39, 1.90 and 1.73; 95% CI 0.27 to 0.57, 1.33 to 2.71 and 1.02 to 2.39; P<0.01 or <0.05). Conclusions:The use of COOK balloon and Foley balloon to prevent adhesion is better than the use of intrauterine devices in preventing re-adhesion in patients with moderate or severe intrauterine adhesions.

Immediate Postpartum Insertion of Copper Intrauterine Device in a Brazilian University Hospital: Expulsion and Continuation Rates / Inserção de dispositivo intrauterino de cobre no pós-parto imediato em hospital universitário brasileiro: Taxas de expulsão e continuação

Abstract Objective To evaluate the expulsion and continuation rates of the copper intrauterine device (IUD) inserted in the immediate postpartum period in a Brazilian public university hospital. Materials and Methods In the present cohort study, we included women who received immediate postpartum IUD at vaginal delivery or cesarean s March 2018 to December 2019. Clinical data and the findings of transvaginal ultrasound (US) scans performed 6-weeks postpartum were collected. The expulsion and continuation rates were assessed 6-months postpartum using data from the electronic medical records or by telephone contact. The primary outcome was the proportion of IUDs expelled at 6 months. For the statistical analysis, we used the Student t-test, the Poisson distribution, and the Chi-squared test. Results There were 3,728 births in the period, and 352 IUD insertions were performed, totaling a rate of 9.4%. At 6 weeks postpartum, the IUD was properly positioned in 65.1% of the cases, in 10.8% there was partial expulsion, and in 8.5% it had been completely expelled. At 6 months postpartum, information was obtained from 234 women, 74.4% of whom used IUD, with an overall expulsion rate of 25.6%. The expulsion rate was higher after vaginal delivery when compared with cesarean section (68.4% versus 31.6% respectively; p = 0.031). There were no differences in terms of age, parity, gestational age, final body mass index, and newborn weight. Conclusion Despite the low insertion rate of copper IUDs in the postpartum period and a higher expulsion rate, the rate of long-term continuation of intrauterine contraception was high, indicating that it is a useful intervention to prevent unwanted pregnancies and to reduce short-interval birth.

Resumo Objetivo Avaliar as taxas de expulsão e continuação do dispositivo intrauterino (DIU) de cobre inserido no pós-parto imediato em um hospital universitário brasileiro. Materiais e Métodos Neste estudo de corte transversal, foram incluídas parturientes submetidas à inserção de DIU de cobre no pós-parto imediato entre março de 2018 e dezembro de 2019. Foram coletados dados clínicos e da ultrassonografia (US) transvaginal realizada após seis semanas. As taxas de expulsão e de continuação foram avaliadas após seis meses por meio de dados do prontuário ou por contato telefônico. O resultado principal foi a proporção de DIUs expelidos em seis meses. Para análise estatística, utilizaram-se o teste t de Student, a distribuição de Poisson, e o teste do Qui quadrado. Resultados Houve 3,728 nascimentos no período, e foram inseridos 352 DIUs, em uma taxa de 9,4%. Com 6 semanas, o DIU estava bem posicionado em 65,1% dos casos, em 10,8%, houve expulsão parcial, e, em 8,5%, fora totalmente expelido. Aos 6 meses de pós-parto, foram obtidas informações de 234 mulheres, 74,4% das quais usavam DIU, com uma taxa de expulsão geral de 25,6%. A taxa de expulsão foi maior após o parto vaginal do que após cesariana (68,4% versus 31,6%, respectivamente; p = 0,031). Não houve diferenças quanto à idade, paridade, idade gestacional, índice de massa corpórea final, e peso do recém-nascido. Conclusão Apesar da baixa taxa de inserção e alta taxa de expulsão, a taxa de continuação em longo prazo da contracepção intrauterina com DIU de cobre foi elevada, o que indica que se trata de intervenção útil para prevenir gestações indesejadas em curto intervalo de tempo.

Vesico-utero-sigmoid fistula secondary to a migrated intra-uterine contraceptive device to the urinary bladder: A rare urogenital complication

@#Vesico-utero-sigmoid fistula secondary to an encrusted, transmigrated intrauterine contraceptive device (IUCD) to the urinary bladder is a rare urogenital occurrence. Reported here is a case of a 42-year-old female with 13 years of IUCD presenting with a two-year history of terminal dysuria, occasional hematuria and urinary dribbling. In the interim, she complained of persistent wet stools, pneumaturia, fecaluria and occasional urinary incontinence. Imaging revealed an encrusted IUCD with a concomitant vesico-utero-sigmoid fistula. Patient underwent a single setting colonoscopy, vagino-hysteroscopy, cystoscopy with cystostomy and extraction of encrusted foreign body (IUCD), excision and primary repair of vesico-utero-sigmoid fistula was done. The surgery proved successful, greatly improving the patient’s quality of life. This is the first reported case of a vesico-utero-sigmoid fistula caused by a foreign body both in local and international literature.

Dificuldade relatada na inserção do dispositivo intrauterino na Atenção Primária à Saúde / Reported difficulty in inserting the intrauterine device in Primary Health Care

O Dispositivo Intrauterino (DIU) é um método contraceptivo que encontra vários entraves para a ampliação da sua oferta na Atenção Primária à Saúde (APS). Uma das principais barreiras à sua inserção é a falta de treinamento dos profissionais. Por isso, o presente estudo tem como objetivo descrever as dificuldades encontradas nos procedimentos de inserção do DIU na Atenção Primária e os fatores associados a essa dificuldade. Foi feita a tentativa de realizar a inserção do DIU nas Unidades Básicas de Saúde (UBS) em 152 mulheres em idade reprodutiva. Os dados foram coletados através de um questionário estruturado em amostragem não-probabilística por conveniência. A idade média das mulheres foi de 27 anos e 26,3% (40) dos procedimentos foram considerados com algum grau de dificuldade. O escore médio de dor foi maior nos procedimentos que apresentaram dificuldade, sendo de 4,59 e de 5,7 nas inserções sem e com dificuldade, respectivamente (p<0.0001). A média de tempo de formado entre os médicos que tiveram dificuldade foi de 33,5 meses e entre aqueles que não tiveram dificuldade foi de 64 meses (p< 0,0001). Entre as dificuldades, a mais referida foi o momento de realizar a histerometria. Outras dificuldades também foram encontradas: identificar e pinçar o colo uterino e identificar posição uterina.

The Intrauterine Device (IUD) is a contraceptive method that faces several obstacles to expanding its offer in Primary Health Care. One of the main barriers to its insertion is the lack of training of professionals. Therefore, this study aims to describe the difficulties found in IUD insertion procedures in Primary Care and the factors associated with this difficulty. An attempt was made to insert the IUD in the Basic Health Units in 152 women of reproductive age. Data were collected through a structured questionnaire in non-probabilistic convenience sampling. The mean age of women was 27 years and 26.3% (40) of the procedures were considered to have some degree of difficulty. The mean pain score was higher in procedures that presented difficulty, being 4.59 and 5.7 in insertions without and with difficulty, respectively (p<0.0001). The average time since graduation among physicians who had difficulty was 33.5 months and among those who had no difficulty, it was 64 months (p<0.0001). Among the difficulties, the most mentioned was the time to perform the hysterometry. Other difficulties were also encountered: identifying and clamping the cervix and identifying the uterine position

Introdução: A inserção do dispositivo intrauterino é uma competência esperada para o médico generalista. No entanto, esse método encontra muitas barreiras ao ser inserido nas unidades básica de saúde, como a falta de treinamento dos profissionais e o medo que as mulheres têm de sentir dor. Objetivo: Avaliar a intensidade da dor durante o procedimento de inserção do dispositivo intrauterino realizado por médicos generalistas em unidades básicas de saúde na região metropolitana de João Pessoa e sua associação com fatores sociodemográficos, aspectos clínicos da mulher e formação médica. Métodos: Estudo transversal e descritivo, com dados coletados em 16 unidades básicas de saúde nos municípios de Conde, Caaporã, João Pessoa e Sapé, no intervalo de março a outubro de 2019. A coleta de dados foi realizada por entrevista individual com questionário estruturado, e a dor foi graduada pela escala visual analógica. Os dados foram analisados utilizando-se os testes de Mann-Whitney e χ². Resultados: Participaram do estudo 139 mulheres com idade mínima de 14 e máxima de 47 anos, cuja média de dor foi de 5,5 para aquelas que estavam menstruadas e de 4,6 para as que não estavam. A dor leve esteve presente em 20,1%, a dor moderada em 38% e dor intensa em 31,7%. Histerometria acima de 7 cm, histórico de uso de anti-inflamatórios na menstruação e de dismenorreia estiveram mais presentes em quem referiu dor intensa (p<0,001). Quanto à qualificação do médico que insere o dispositivo intrauterino, não houve significância estatística na correlação de dor intensa com o fato de ele ser residente (p=0,268), com o tempo de formatura (p=0,080) nem com a dificuldade técnica encontrada (p=0,065). Conclusões: A dor foi considerada pela maioria das mulheres como moderada, sendo uma oferta e um procedimento viável de ser ensinado e inserido na Atenção Primária à Saúde.

Introduction: The insertion of the intrauterine device is an expected competence for the general practitioner. However, this method faces many barriers to be inserted in health centers such as the lack of professionals' training and women's fear of feeling pain. Objective: To evaluate the intensity of pain during the intrauterine device insertion procedure performed by general practitioners in health centers in the metropolitan region of João Pessoa and its association with sociodemographic factors, clinical aspects of women, and medical training. Methods: This is a cross-sectional and descriptive study, based on data collected from 16 health centers in the cities of Conde, Caaporã, João Pessoa, and Sapé (state of Paraíba, Brazil) from March to October 2019. Data collection was carried out by individual interview with a structured questionnaire and pain was rated by the Visual Analog Scale. Data were analyzed using Mann-Whitney Test and Pearson's Chi-square Test. Results: The study included 139 women aged between 14 and 47 years, whose mean pain was 5.5 for those who were menstruating and 4.6 for those who were not. Mild pain was present in 20.1%; moderate pain, in 38%; and intense pain, in 31.7%. Hysterometry above 7cm, history of use of anti-inflammatory drugs during menstruation, and dysmenorrhea were more present in those who reported intense pain (p<0.001). Regarding the qualification of the physician who inserts the intrauterine device, there was no statistical significance in the correlation of intense pain with being a resident (p=0.268), time since graduation (p=0.080), or technical difficulty encountered (p=0.065). Conclusions: Therefore, pain was mostly considered as moderate, and IUD insertion is a feasible offer and procedure to be taught and implemented in Primary Health Care.

Análisis y consideraciones técnicas acerca de dispositivos intrauterinos de levonorgestrel para la evaluación de productos similares y genéricos / Analysis and technical considerations about levonorgestrel intrauterine devices for the evaluation of generic and similar products

Los dispositivos intrauterinos hormonales de levonorgestrel son métodos anticonceptivos seguros y eficaces. Al igual que los medicamentos convencionales, una vez expirada la patente, las autoridades regulatorias de salud pueden aprobar el registro de productos similares. El objetivo de ello es disminuir los costos, considerando el elevado precio del producto original. Este tipo de productos están regulados y se aplican requisitos generales similares a los medicamentos tradicionales para demostración de seguridad y eficacia. Las propiedades mecánicas únicas del producto de referencia plantean un gran desafío a los productos similares. El presente artículo analiza de manera comparativa las características de los diversos sistemas intrauterinos hormonales de levonorgestrel, disponibles en el mercado. La autoridad sanitaria y los diversos centros clínicos deben considerar que en este tipo de productos no hay, hasta la fecha en el mundo, genéricos intercambiables y que por lo tanto, se debe decidir la intercambiabilidad de éstos sobre la base de estudios de bioequivalencia in vivo, luego de la demostración de equivalencia farmacéutica in vitro, tal y como sugiere la FDA, o en su defecto deberían ser registrados como productos nuevos, con estudios clínicos apropiados que demuestren seguridad y eficacia.

Levonorgestrel hormonal intrauterine systems are safe and effective contraceptive methods. Like conventional drugs, once the patent expires, health regulatory authorities can approve the registration of similar products. The objective of this is to reduce costs, considering the high price of the original product. These types of products are regulated as drugs and similar general requirements apply to traditional drugs for demonstration of safety and efficacy. The unique mechanical properties of the reference product pose a great challenge to similar products. This article comparatively analyzes the characteristics of the various levonorgestrel hormonal intrauterine systems available on the market. Therefore, the health authority and clinical centers must consider that up to date, there are no interchangeable generics in this type of products worldwide. Thus, their interchangeability must be decided on the basis of in vivo bioequivalence studies after the demonstration of in vitro pharmaceutical equivalence, as suggested by the FDA. Without that, they should be registered as new products, with appropriate clinical studies that demonstrate safety and efficacy.

Actinomicosis pélvica invasiva: un desafío para el ginecólogo / Invasive pelvic actinomycosis: a challenge for the gynecologist

Resumen La actinomicosis pélvica es una infección bacteriana supurativa crónica, producida por especies de Actinomyces, principalmente Actinomyces israelii, que afecta el aparato genital interno y las estructuras vecinas, asociada al uso prolongado de dispositivo intrauterino sin control en casi la totalidad de los casos descritos en mujeres. La actinomicosis pélvica suele presentarse como un absceso tubo-ovárico y con menor frecuencia como una actinomicosis pélvica invasiva (API). La API se propaga por contigüidad desde el aparato genital hacia las vísceras adyacentes, originando un tumor pélvico difuso, de consistencia leñosa, pseudotumoral, que a menudo se confunde con una neoplasia pélvica. La API representa un gran desafío para el ginecólogo por las dificultades en su diagnóstico y manejo. Se presentan dos casos de API y se revisan los procedimientos diagnósticos y terapéuticos recomendados actualmente para el enfrentamiento de esta patología.

Abstract Pelvic actinomycosis (PA) is a chronic suppurative bacterial infection, produced by Actinomyces, mainly Actinomyces israelii. It affects the internal genital tract, adjacent structures and is associated with a prolonged intrauterine device use with an inadequate control in almost all described cases in women. Pelvic actinomycosis usually presents as a tube ovarian abscess and less frequently as invasive pelvic actinomycosis (IPA). The IPA spreads contiguously from the genital tract to adjacent viscera, causing a diffuse, woody, pseudotumoral pelvic tumor that is frequently confused with a pelvic neoplasm. The IPA represents a great challenge for the gynecologist due to the difficulties in the diagnosis and management of this disease. Two cases of IPA are presented and the currently recommended diagnostic and therapeutic procedures for dealing with this pathology are reviewed.

Fístula utero-yeyunal secundaria a migración de dispositivo intrauterino: reporte de un caso / Utero-jejunal fistula secondary to intrauterine device migration: a case report

RESUMEN El dispositivo intrauterino (DIU) es un método anticonceptivo muy popular, eficaz y seguro. Aunque posee complicaciones bien descritas como es la migración, la que puede ser a otros órganos dentro de la cavidad peritoneal. La fístula uteroyeyunal es un evento clínico poco frecuente, pero de gran repercusión si no es diagnosticada y tratada. Se presenta el caso de una paciente usuaria de DIU, el que migra a cavidad abdominal, con posterior formación de fístula uteroyeyunal.

ABSTRACT The intrauterine device is a popular, efficient and safe contraceptive. Although it has some well described complications, such as migration, which may be to the different organs inside of the peritoneal cavity. The uterus-jejunal fistula is a rare clinical event, but with great repercussion if it is not well assessed and treated properly. We present the clinical case of a patient with a migrated intrauterine device and a fistula uterus-jejunal formation.

Postplacental placement of intrauterine devices: acceptability, reasons for refusal and proposals to increase its use / Dispositivo intrauterino pós-placentário: Aceitação, motivos de recusas e propostas de ações que ampliem sua prática

Abstract Objective To evaluate the acceptability of postplacental placement of intrauterine devices (PPIUD), reasons for refusal and suggested policies to increase its use. Methods Cross-sectional study conducted at the Women Hospital of the Universidade de Campinas, Campinas, SP, Brazil. Postplacental placement of intrauterine devices was offered to women admitted in labor who did not present infections, uterinemalformation, twin pregnancy, preterm birth, and were at least 18 years old. In case of refusal, the parturient was asked to give their reasons and the answers were classified as misinformation about contraception or other reasons. The following were considered misinformation: fear of pain, bleeding, contraception failure and future infertility. Bivariate analysis was performed. Results Amongst 241 invited women, the refusal rate was of 41.9%. Misinformation corresponded to 50.5% of all refusals, and the reasons were: fear of pain (39.9%); fear of contraception failure (4.9%); fear of bleeding (3.9%); fear of future infertility (1.9%); other reasons for refusal were 49.5%. Parturients aged between 18 and 27 years old refused the PPIUD more frequently due to misinformation (67.4%), and older parturients (between 28 and 43 years old) refused frequently due to other reasons (63.6%) (p=0.002). Themean age of those who declined the PPIUD due to misinformation was 27.3 ± 6.4 years old, while those who declined for other reasons had a mean age of 29.9 ± 5.9 years old (p=0.017). Conclusion The refusal of the PPIUD was high, especially amongst young women and due to misinformation. It is necessary to develop educative measures during antenatal care to counsel women about contraception, reproductive health and consequences of unintended pregnancy.

Resumo Objetivo Avaliar a taxa de aceitação do dispositivo intrauterino pós-placentário (DIUPP); os motivos de recusa e propor medidas que aumentem sua aceitação. Métodos Estudo de corte transversal realizado no Hospital daMulher da Universidade Estadual de Campinas, Campinas, SP, Brasil. O DIUPP foi oferecido amulheres admitidas em trabalho de parto que não apresentavam: infecções,malformação uterina, gravidez gemelar, parto prematuro e com idade mínima de 18 anos. Em caso de recusa, perguntou-se o motivo, e as respostas foram agrupadas em informações equivocadas sobre contracepção ou outros motivos. Considerou-se informação equivocada: medo de dor, sangramentos, falha da contracepção e prejuízo da fertilidade. Análises bivariadas foram realizadas. Resultados Entre 241 mulheres, a taxa de recusa foi de 41,9%. A desinformação correspondeu a 50,5% de todos osmotivos de recusa, que foram:medo da dor (39,9%); medo da falha da contracepção (4,9%); medo de sangramento (3,9%), medo de o dispositivo intrauterino (DIU) prejudicar a fertilidade (1,9%). Outros motivos de recusa atingem 49,5%. Parturientes com idade entre 18 e 27 anos recusaram o PPIUD com mais frequência devido a desinformação (67,4%), e as mais velhas (com idade entre 28 e 43 anos) recusaram com frequência devido a outros motivos (63,6%) (p=0,002). Houve diferença entre a idade média de quem recusou o PPIUD por desinformação (27,3 ± 6,4 anos) em comparação com outras razões (29,9 ± 5,9 anos), (p=0,017). Além disso, ambos os grupos apresentaram altas taxas de recusa por desinformação, de 67,4 e 36,4%, respectivamente. Conclusão A recusa do DIUPP foi alta, principalmente entre as mulheres jovens e por desinformação. Diante disso, é necessário o desenvolvimento de medidas educativas durante o pré-natal e aconselhar as mulheres sobre contracepção, saúde reprodutiva e gravidez indesejada.

Migración de dispositivo intrauterino a vejiga / Intrauterine device migration to bladder

Introducción: La litiasis vesical secundaria se forma en el reservorio vesical y requiere la existencia de condiciones patológicas previas como lo son los cuerpos extraños. Objetivo: Describir dos casos clínicos de litiasis vesical secundaria a migración de un dispositivo intrauterino. Caso clínico: Se presentan dos casos de migración intravesical de dispositivo intrauterino con litiasis vesical secundaria. Se diagnosticaron años después de su inserción, ante la aparición de dolor pélvico, cistitis a repetición y hematuria. La laparoscopia no fue útil para su diagnóstico. En consulta de Urología la ultrasonografía y la radiografía de pelvis fueron herramientas diagnósticas útiles ante la sospecha inicial de esta patología. Presentaron buena evolución y regresión total de los síntomas tras cistolitotomía suprapúbica. Conclusión: Se debe pensar en la posibilidad de migración de un dispositivo intrauterino a vejiga ante la cronicidad de síntomas urinarios irritativos bajos en toda mujer que emplee este método anticonceptivo y desconozca su paradero(AU)

Introduction: Secondary bladder lithiasis is formed in the bladder reservoir and requires the existence of previous pathological conditions such as foreign bodies. Objective: To describe two clinical cases of bladder lithiasis secondary to intrauterine device migration. Clinical case report: Two cases of intravesical migration of an intrauterine device with secondary bladder stones are reported. They were diagnosed years after insertion, due to the appearance of pelvic pain, recurrent cystitis and hematuria. Laparoscopy was not helpful for its diagnosis. In Urology consultation, ultrasound and pelvic radiography were useful diagnostic tools in the event of the initial suspicion of this pathology. They showed good evolution and total regression of symptoms after suprapubic cystolithotomy. Conclusion: The possibility of an intrauterine device migration to the bladder should be considered when chronicity of irritative low urinary symptoms in every woman who uses this contraceptive method and which locations are unknown(AU)

Remoção histeroscópica de sistema intrauterino em gestação inicial: revisão de literatura / Hysteroscopic removal of the intrauterine system in early pregnancy: a literature review

Os dispositivos intrauterinos (DIUs) são os métodos contraceptivos reversíveis de longa duração mais utilizados no mundo, apresentando altas taxas de eficácia e segurança. Na presença de gestação, o DIU pode ser retirado com uma leve tração dos fios, quando visíveis. Na impossibilidade de visualização dos fios, há a opção de retirada por histeroscopia, que tem se mostrado segura e eficaz para a retirada de DIU retido na cavidade. Foram pesquisados os termos: "intrauterine device", "pregnancy" e "hysteroscopy". Dos 378 artigos encontrados, foram selecionados 18 artigos que cumpriam os objetivos desta revisão. A presença de DIU durante a gestação se mostra um fator de risco independente para desfechos desfavoráveis como abortamento, corioamnionite, parto prematuro e maior taxa de admissão em unidade de terapia intensiva neonatal. A histeroscopia ambulatorial se mostra uma alternativa segura e eficaz na retirada do DIU no primeiro trimestre.(AU)

Intrauterine devices (IUDs) are the most widely used reversible contraceptive methods in the world, with high rates of efficacy and safety. In the presence of pregnancy, the IUD can be removed by gently traction of the threads, when visible. If the wires cannot be visualized, we have the option of hysteroscopy removal, which has been shown to be safe and effective for the removal of an IUD retained in the cavity. The terms "intrauterine device", "pregnancy" and "hysteroscopy" were searched. Of the 378 articles found, 18 articles were selected that met the objectives of this review. The presence of IUDs during pregnancy is an independent risk factor for unfavorable outcomes such as abortion, chorioamnionitis, premature birth and a higher rate of admission to a neonatal intensive care unit. Ambulatory hysteroscopy is a safe and effective alternative for IUD removal in the first trimester.(AU)

Postpartum intrauterine contraceptive device: effect of antenatal versus postpartum counselling in acceptance of postpartum intrauterine contraceptive device

Background: The acceptance for PPIUCD in our country, especially in rural areas is very low despite all the efforts. Counselling during the antenatal visits may play a vital role in improving the acceptance of PPIUCD. Objective of this study was to assess the factors associated with the acceptability of immediate PPIUCD insertion in women; counselled during antenatal and postpartum period; according to their sociodemographic and obstetric characteristics, and future pregnancy desires.Methods: One-year prospective study carried out in the department of obstetrics and gynecology, S. S. Medical College Rewa, Madhya Pradesh, India. a total of 4850 women were counselled for PPIUCD insertion; 2540 during their antenatal visits, and 2310 during postpartum period who visited in study centre for first time and their follow up was done. Chi square tests were applied to compare proportions.Results: After antenatal counselling in 2540 women, (with multiple counselling sessions) about half of the women gave verbal acceptance for PPIUCD. However, during postpartum counselling in 2310 women, (where only single short session of counselling could be done) majority of the women declined (80.9%) for PPIUCD insertion with only about a fifth (19.1%) of the women giving verbal acceptance. Women who had antenatal counselling one third of them had PPIUCD insertion. In the postpartum counselling group, a meagre 15.1% women had PPIUCD insertion.Conclusions: Counselling during antenatal and postpartum period is the key to improve the awareness and acceptance of PPIUCD in our community. Multiple counselling sessions during antenatal visits make it easier for the women to slowly understand the process and accept PPIUCD as compared to the short counseling during postpartum period.

Clinical outcome of post-abortion intrauterine contraceptive device insertion

Background: Clinical outcome of post abortion IUCD varies according to type of abortion, method of abortion and period of abortion. There is paucity of Indian literature regarding factor affecting clinical outcome of post-abortal intrauterine contraceptive device insertion. This study was conducted to evaluate clinical outcome of post abortion intrauterine contraceptive in terms of acceptability, safety and continuation rate.Methods: A prospective cohort study where 112 patients over period of 18 months (November 2017 to April 2019) were included in study done at VMMC and Safdarjung Hospital, New Delhi, India.Results: Total 112 patients recruited. Their age ranges from 26-30 years. Mean age of women were 28.11±4.51 years. Majority of women who underwent IUCD insertion were para2. Regardless of type of IUCD, the most common side effects associated with copper wearing IUCD were change in amount of menstrual flow. Two cases of PID after CuT380A insertion and one case of PID after cu375. No perforation occurred. Continuation rate were 86.79%. Satisfaction rate were 82.14%.Conclusions: There is higher rate of continuation and satisfaction among women who had undergone immediate post abortion OUCD insertion. Early insertion of IUCD after abortion is safe, effective and well tolerated by women. Clinical outcome of post abortion is not affected by type of copper containing IUCD i.e., Cu380A and Cu375.

Intrauterine device insertion during cesarean section in women without prenatal contraception counseling: lessons from a country with high cesarean rates / Inserção de dispositivo intrauterino durante a cesárea em mulheres sem aconselhamento contraceptivo pré-natal: lições de um país com elevada taxa de cesárea

Abstract Objective Themoment of admission for deliverymay be inappropriate for offering an intrauterine device (IUD) to women without prenatal contraception counseling. However, in countries with high cesarean rates and deficient prenatal contraception counseling, this strategy may reduce unexpected pregnancies and repeated cesarean sections. Methods This was a prospective cohort study involving 100 women without prenatal contraception counseling. Postplacental IUD was offered after admission for delivery and placed during cesarean. The rates of IUD continuation, uterine perforation, and endometritis were assessed at 6 weeks and 6 months, and the proportion of women continuing with IUD at 6 months was assessed with respect to the number of previous cesareans. Results Ninety-seven women completed the follow-up. The rate of IUD continuation was 91% at 6 weeks and 83.5% at 6 months. The expulsion/removal rate in the first 6 weeks was not different from that between 6 weeks and 6 months (9 vs 9.1%, respectively). There were 2 cases of endometritis (2.1%), and no case of uterine perforation. Among 81 women continuing with intrauterine device after 6-months, 31% had undergone only the cesarean section in which the IUD was inserted, 44% had undergone 2 and 25% had undergone 3 or more cesarean sections. Conclusion Two thirds of the women who continued with IUD at 6 months had undergone 2 ormore cesarean sections. Since offering trial of labor is unusual after 2 or more previous cesareans, we believe that offering IUD after admission for delivery may reduce the risk of repeated cesarean sections and its inherent risks.

Resumo Objetivo O momento da admissão para o parto pode ser considerado inapropriado para oferecer o dispositivo intrauterino (DIU) para mulheres sem aconselhamento contraceptivo pré-natal. Entretanto, em países com elevadas taxas de cesáreas e aconselhamento contraceptivo deficiente, essa estratégia pode reduzir o risco de gestações não programadas e cesáreas repetidas. Métodos Estudo de coorte envolvendo 100 mulheres sem aconselhamento contraceptivo pré-natal. A inserção de DIU pós-dequitação foi oferecida após a admissão para o parto e indicação de cesárea. As taxas de continuidade com o DIU, perfuração uterina e endometrite foram avaliadas após 6 semanas e 6 meses, e a proporção de mulheres que continuaram com o DIU após 6 meses foi analisada em relação ao número de cesáreas prévias. Resultados Noventa e sete mulheres completaram o seguimento. A taxa de permanência do DIU foi de 91% em 6 semanas e 83,5% em 6 meses. A taxa de expulsão/ remoção nas primeiras 6 semanas foi não foi diferente daquela observada entre 6 emanas e 6 meses (9 vs 9,1%, respectivamente). Houve dois casos de endometrite (2,1%), e nenhum caso de perfuração uterina. Entre as 81mulheres que permaneceram como DIU após 6 meses, 31% haviam sido submetidas a apenas uma cesárea, em que o DIU foi inserido, 44% a 2, e 25% a 3 ou mais cesáreas. Conclusão Dois terços das mulheres que continuaram com o DIU após 6 meses haviam sido submetidas a 2 ou mais cesáreas. Considerando que oferecer a tentativa de parto vaginal após duas oumais cesáreas prévias é incomum, é possível que a oferta do DIU na admissão para o parto possa reduzir o risco de cesáreas repetidas e de seus riscos associados.
