Cortisol and Anxiety Response to a Relaxing Intervention on Pregnant Women Awaiting Amniocentesis

Background: Stress and anxiety during pregnancy have been associated with premature and low birth weight babies, presumably through fetus over exposion to glucocorticoids. Antenatal stress also seems to have long-term effects upon infant development and adult health. However, medication for stress may carry risks to the expectant mother, therefore the efficacy of nonpharmacological interventions should be investigated. Methods: Pregnant women (n = 154) awaiting amniocentesis, were randomly assigned in the morning and the afternoon to three groups for 30 min: (1) listening to relaxing music, (2) sitting and reading magazines, and (3) sitting in the waiting-room. Before and after that period, they completed the Spielberger’s State and Trait anxiety inventory and provided blood samples for cortisol. The groups were then compared regarding change in cortisol levels and anxiety. Results: Maternal cortisol and state anxiety were correlated (r = 0.25, p = 0.04) in the afternoon, but not in the morning. The larger decreases in cortisol occurred in the music group ( 61.8 nmol/L, ANOVA: p = 0.01), followed by magazine, being differences among groups more pronounced in the morning. Women in the music group also exhibited the greater decreases in state anxiety ( p < 0.001). Younger mothers with less gestational age were on average the most anxious, and also the ones with greater decreases in cortisol and anxiety levels after relaxation. Conclusion: A relaxing intervention as short as 30 min, especially listening to music, decreases plasma cortisol and self-reported state anxiety score. Pregnant women might benefit from the routine practice of relaxation in the imminence of clinical stressful events.

Amniocentesis in HIV Pregnant Women: 16 Years of Experience

The iatrogenic risk of HIV vertical transmission, calculated in initial epidemiologic studies, seemed to counterindicate invasive prenatal diagnosis (PND) procedures. The implementation of highly active antiretroviral therapy (HAART) represented a turning point in PND management, owing to a rapid and effective reduction of maternal viral load (VL). In the present study, we identified cases of vertical transmission in HIV-infected pregnant women who did amniocentesis in the second trimester of pregnancy (n = 27), from 1996 to 2011. We divided our sample into Group A--women under HAART when submitted to amniocentesis (n = 20) and Group B--women without antiretroviral therapy before amniocentesis (n = 7). We had 1 case of vertical transmission in Group B. Preconceptional or early first trimester HIV serology is essential to avoid performing an amniocentesis without antiretroviral therapy or viral suppression. When there is an indication for amniocentesis in an HIV-infected pregnant woman, it should be done if the patient is on HAART and, if possible, when VL is undetectable. Nowadays, with combined first trimester screening test to select pregnancies with high risk of aneuploidies, advanced maternal age is a less frequent indication to perform PND invasive procedures, representing an outstanding gain in prenatal diagnosis of this population.

Fulminant Hepatitis E in a Pregnant Woman

Hepatitis E is an inflammatory liver disease caused by hepatitis E virus (HEV) infection, which is endemic in China, India, Nepal, and in several Asian and African countries, where the prevalence can be as high as 50%. In non-endemic countries, an increasing number of non-travel associated HEV has been reported in recent years, particularly in Europe. The authors describe the clinical case of a puerperal 24-year-old woman from Pakistan admitted to our Tertiary Care Medical Center with acute hepatic failure developed during the third trimester of her pregnancy. She was icteric with grade III encephalopathy and hypothermia. Laboratory values showed significant AST, ALT and LDH elevations of twelve times the upper normal limit, and total bilirubin was significantly elevated (41.20 mg/dL). Prothrombin time was prolonged (4 s) and factor V activity was diminished (15.1%). Extracorporeal albumin dialysis was initiated, but clinical deterioration occurred within 48 h, so she underwent OLT at day 4 post-admission. Severe forms of HEV are known to be more pronounced in pregnant women. Even though most of the described cases of acute hepatic failure associated to HEV during pregnancy had a favorable clinical course, some cases of fulminant liver failure and death are described. It is unknown whether liver transplant outcomes in this setting are different from other causes of acute liver failure. To our knowledge, this is the first case report in Portugal from a pregnant woman who developed hepatic failure due to fulminant hepatitis E that underwent successful liver transplantation.

Aspectos Imagiológicos da Trombose Venosa Cerebral numa Mulher Grávida

A trombose venosa cerebral (TVC) é uma doença relativamente rara mas grave, potencialmente reversível com diagnóstico atempado e terapêutica médica adequada. A gravidez e o puerpério são um factor predisponente de TVC, que é responsável por 6% das causas de morte materna. As manifestações clínicas dependem da localização, extensão do trombo, bem como da rede de colaterais existente. Apresentamos o caso duma doente do sexo feminino, 33 anos, grávida de 13 semanas que recorreu ao serviço de urgência por quadro de cefaleias e cujo estudo por Ressonância Magnética revelou aspectos compatíveis com doença venosa oclusiva subtotal do seio longitudinal superior em fase aguda. A propósito deste caso discutimos as manifestações imagiológicas da trombose venosa dural na fase aguda.

Avaliação da Analgesia Após Cesariana

OBJECTIVE: The aim of this study was to evaluate the efficacy of post-caesarean analgesia comparing three techniques most frequently used. PATIENTS AND METHODS: For three months all pregnant women submitted to elective or urgent caesarean section, under general or regional anaesthesia, were evaluate with a total of 129 parturient. These parturient were divided into three groups with different techniques of postoperative analgesia: Group 1 (n = 26) received intravenous pethidine and paracetamol per os, group 2 (n = 58) received epidural morphine and group 3 (n = 45) epidural morphine and intravenous propacetamol. Pain was assessed at rest and during mobilisation using a scale of 0-without pain, 1-mild pain, 2-moderate pain and 3-severe pain. Overall satisfaction was assessed with a verbal qualitative scale of very good, good, sufficient and bad. Side effects were analysed. RESULTS: The records of pain at rest and during mobilisation were significantly lower with epidural analgesia compared with intravenous pethidine. There were no significant differences between groups 2 and 3. Similar results were observed in the degree of satisfaction. For 50% of parturient of epidural analgesia (groups 2 and 3) and only 4% of intravenous pethidine (group 1) the analgesic technique was very good. Propacetamol and epidural morphine (group 3) had better pain scores (very good and good) when compared with morphine alone (group 2) but there were no significant differences. Epidural morphine was associated with more pruritus. CONCLUSION: From this study we are able to conclude that epidural morphine offers a good quality of analgesia with better satisfaction and minimal side effects.

Infecções Urinárias e Gravidez - Diagnóstico, Terapêutica e Prevenção

Objectives: Literature review of classification, epidemiology, pathophysiology, microbiology, clinical presentation, diagnosis, complications, treatment and prevention of urinary tract infections (UTI) in pregnancy. Data Sources and Review Methods: Bibliographic research in Medline, through PubMed and Medscape, of systematic reviews, observational studies, clinical guidelines, meta-analyses and randomized controlled trials published between January 1992 and December 2010. Results: Asymptomatic bacteriuria occurs in 2 to 10% of pregnant women, 30% of which will develop acute pyelonephritis if left untreated. Treatment of asymptomatic bacteriuria has been shown to reduce the risk of pyelonephritis in pregnancy. Therefore, screening and treatment of this form of UTI has become a standard of obstetrical care, although the ideal duration of the treatment is still controverse. Acute pyelonephritis is one of the most common medical complications of pregnancy and may be associated with maternal, obstetric and perinatal complications. There is no clear consensus in the literature regarding antibiotic choice or duration of therapy for symptomatic UTI. Increasing antibiotic resistance complicates the choice of empirical regimens and local resistance rates need to be taken into account when deciding the therapy. Considering the high rate of recurrence of UTI during pregnancy, prophylactic measures need to be taken in pregnant women who have already experienced UTI during their current pregnancy. Conclusions: Although UTI is a generally benign condition in non-pregnant women, it may be a potentially serious complication during pregnancy. Early diagnosis and treatment of UTI during pregnancy are mandatory and can prevent severe maternal and perinatal complications.

Perinatal Bacterial Infection: Screenning of Vertical Transmitted Infections

Perinatal bacterial infection may be caused by any microorganism colonizing the vaginal tract. Neonatologists and paediatricians are especially concerned about group B Stretpococcus (GBS). However, Enterobactereacea, mainly E.coli and Proteus, are also responsible for infection. GBS screening may be accomplished in over 90% of pregnant women. In our maternity in 2007-2008, 85% of the mothers had been screened. Screening and prophylaxis were responsible for a decreasing incidence of neonatal infection - from 0.6/1000 to 0.15/1000 live births in Portugal, from 2002 to 2007. However there are some difficulties related to screening. In the second Portuguese study 16/57 NB with early-onset infection (28%) were born to “negative” mothers. Several factors illustrate how difficult is to draw national screening policies: a wide range of carrier’s state rate throughout a country - in Portugal from 12% to 30%. The success of any screening policy may also be affected by additional technical and organizational problems. In countries where home delivery is a tradition or a trend intrapartum GBS prophylaxis requires a very well organized assistance.. Moreover factors usually accepted as protective are not so effective. In the Portuguese study 24/57 infected newborns (42%) were delivery by caesarean section. Another subject deals with the workload in the postnatal ward generated by deficient compliance to the guidelines a problem not confirm by a study of our group. Decreasing the importance of GBS, highlight the importance of E. coli in perinatal infection. From the 16 340 registrations of the National Registry 1676 were newborns with mother-related infection. Applying the same reasoning to E.coli as to GBS and Listeria monocytogenes – that is considering all of them are of maternal origin - 6.7% of these infections were due to E. coli, 4.6% to SGB and 0.5% to Listeria monocytogenes. In conclusion screening and prophylaxis may be not the best way to prevent all GBS neonatal infections but by now it is the only available procedure. The other bacteria continue to demand a high suspicion level and immediate intervention.

Induced Labor– Is There an Increased Risk of Perinatal Infection?

Objectives: To assess induced labor-associated perinatal infection risk at Hospital D.Estefânia from January to June of 2010 at Hospital de D. Estefânia’s delivery rooms, reviewing the indications for inducing labor as well as the techniques used. Material and Methods: Performing an historical prospective study searching the clinical processes as well as the mother and newborn’s computer database from January to June of 2010. An exposed and an unexposed group were created; the first group comprises pregnant women and their newborns whose labor was induced. The unexposed group is constituted by newborns and pregnant women whose labor was spontaneous. Labor induction was performed using intra-vaginal prostaglandins in women who didn’t start it spontaneously; perinatal infection was defined either clinically or using blood tests. The gestational age was ≥ 37 weeks for both groups. 19 variables were studied for both groups. Results: A total of 190 mother-newborn pairs were included: 55 in the exposed group and 135 in the unexposed group. 3 cases of perinatal infection were reported, two in the exposed group and one in the unexposed group. Preliminary data resulted in a perinatal infection rate of 3.6% in the exposed group and 0.7% in the unexposed group; preliminary data suggest that the risk of perinatal infection may be increased in up to 5-fold when labor is inducted. Conclusions: A larger series of patients and a multivariable analysis using logistic regression are both necessary in order to perform a more thorough assessment of labor induction’s role in perinatal infection risk. One must also try to distinguish labor inducing- and clinical practicesrelated factors.

Ocular Toxoplasmosis Reactivation During Pregnancy – A Case Report

Introduction: Toxoplasmosis is caused by Toxoplasma gondii and may be acquired from food or water contaminated with cat feces or by vertical transmission. Severe fetal complications can overcome during pregnancy. There are also rare case-reports of congenital toxoplasmosis from previously immunized pregnant women; usually these women being had prior retinal toxoplasmic lesions. Immunosuppresion is one of the risk factors which accounts for some of these cases. Case report: 30 year-old pregnant woman, OI 2002, brazilian, previously healthy, admitted in Ophtalmology Department because of sudden left eye amaurosis in June, 2010. The fundoscopy revealed retinal scars suggesting previous infections; she was treated with corticoids and spiramycin for ocular toxoplasmosis reactivation. Previous serum analysis (2008) showed immunity to T. Gondii, but in July the IgM was negative and high levels of specific IgG were found (1227UI/mL). The serologic findings were later confirmed by a more accurate laboratory technique which found the IgM to be also positive. An amniocentesis was performed and it was negative for fetal transmission. Clinical and ultrasound follow-up throughout the rest of the gestational period was normal; daily spiramycin intake was maintained. An uneventful term delivery was performed. Neither the newborn’s serum analysis nor the histopathological study of the placenta were positive for congenital infection. Conclusion: Toxoplasmosis reactivation in pregnant women without immunosuppression is rare but is more likely to occur if previous post-infectious retinal scars are present. T. gondii infection is endemic in Brazil, so the geographical origin is important. If risk factors are present, fundoscopy should be performed every three months during pregnancy and one should always be aware of any visual symptoms. If you suspect reactivation, start medical prophylaxis for fetal transmission, perform amniocentesis and regular ultrasound follow-up.

Two Gestational Sacs, Two Locations - Heterotopic Pregnancy - Case Report

Introduction: Heterotopic pregnancy (HP) is defined as two gestational sacs simultaneously present in two different locations, being the uterus and the fallopian tubes the more common. Sporadic HP is a very rare condition (1:30,000 pregnancies). With the use of medically assisted reproduction the prevalence is significantly higher(1:7,000). Considering spontaneous pregnancy, HP is associated with risk factors, being prior inflammatory pelvic disease the most common. The clinical presentation is similar to that of ectopic pregnancy or spontaneous miscarriage although it is usually a more late diagnosis. Case report: 25 year-old pregnant woman, OI 0000, previously healthy; admitted at the Emergency Department (ED) with acute pelvic pain mainly at the right iliac fossa and moderate vaginal bleeding confirmed by speculum examination. She was hemodynamically stable and the bimanual palpation was painful; no prior medically assisted reproduction technique had been performed. The haemoglobin value was within normal range and the serum β-hCG was 2,763mUI/mL. The ultrasonography at the ED showed an in uterus gestational sac and another one inside the right fallopian tube; in both gestational sacs cardiac activity was absent. HP diagnosis was then established and the patient was admitted at the Obstetrics Ward for surveillance and ultrasonographic/laboratorial reassessment; complete miscarriage of the uterine pregnancy occurred but methotrexate was necessary for the treatment of persistent tubarian pregnancy. Conclusion: When evaluating a pregnant woman with pelvic pain and vaginal bleeding one should always be aware of several differential diagnosis amongst which HP should be considered. If the patient has in uterus viable pregnancy the treatment of the ectopic concomitant gestational sac should be as conservative as possible; methotrexate should not be used in that situation as it leads to uterine pregnancy miscarriage in about one third of the patients.

Confined Placental Mosaicism in Chorionic Vilus Sampling - Case Report

Objectives: Chorionic Vilus Sampling (CVS) has several advantages over amniocentesis: it may be performed at an earlier gestational age, the results are quicker to obtain and there’s a lower miscarriage risk – 1%. However, the higher prevalence of discrepant fetal and vilus sampling material’s karyotype findings is a disadvantage of this technique – 0.5%. This is caused, amongst other causes, by placental mosaicism which consists of two genetically different cell lines. There are three types of placental mosaicism according to the abnormal cell line location: Type I – in the cytotrophoblast; Type II – in the vilus’ stroma; Type III – in both the above locations. Material and Methods: We present a case report about a 36-year-old pregnant woman going through our Department’s 1st trimester combined screening program; a CVS was performed, which showed Confined Placental Mosaicism (CPM). Results and Conclusion: Although the pregnant woman was in the low-risk group for aneuploidy, the patient wanted the cytogenetic study to be performed in order to reduce maternal anxiety. CVS was performed at the gestational age of 12 weeks + 5 days and the karyotype was 47XY+2/46XY. For the correct interpretation of this data an amniocentesis was performed at the gestational age of 15 weeks + 6 days, which showed a 46XY karyotype. We therefore conclude that the cytogenetic analysis of the CVS was the result of a CPM. A careful follow-up including fetal echocardiogram and seriated ultrasonographic monitoring was used to safely exclude malformations and fetal growth restriction. We verified no occurences throughout pregnancy, delivery and perinatal period. CVS practice was recently implemented in our country and has many advantages over amniocentesis. Besides the fact that an earlier gestational age usually means less affective bonding to the fetus and therefore makes medical termination of pregnancy somewhat less difficult, one should consider specific situations like the one reported in which CPM may be diagnosed. This condition is associated with increased risk of fetal growth restriction, so the clinician should be aware of the need for a more careful follow-up, since perinatal complications, which should be anticipated and treated, can be expected in 16-21% of these cases.

Why and How Was Regionalization of Perinatal Care Accomplished in Portugal?

Portuguese health care system was created in 1979. It is universal and for free. Expenses are supported by the State through taxes. The modern perinatal care system started by the end of 1970. The first neonatal intensive care units were created in 1980, the Portuguese Neonatal Society in 1985 and the National Neonatal Transport System in 1987. Until the seventies of twentieth century and even during eighties there were more than 200 hospitals with deliveries, a great part without obstetrician or paediatrician, a great percentage of pregnancies had no prenatal care, there were few neonatal intensive care units and perinatal mortality rate was one of the highest in the European countries. In 1987 an Experts Committee was nominated by the Health Ministry aiming to collect and analyse data on perinatal care and to suggest improvements. The Report resulting from this work is the main document on which is based the reform. The reform was a 9 years program in 3 years stages aiming to close hospitals with less than 1500 deliveries/year, to reclassify hospitals, to create Coordinating Units between health centres and hospitals, to equip neonatal intensive and intermediate care units, to define needs of obstetricians, paediatricians and nurses for each centre and to promote specialised training in neonatology for paediatricians and nurses. Levels of perinatal care were defined as well as localization of each level of hospital according to the number of deliveries in one geographic area, geographic difficulties and existing routes and connections. Steps for opening and closure of different levels of hospitals were very well programmed. The organization, capacities, number of obstetricians, neonatologists and nurses as well as equipment for each level of care was defined. Rules for pregnant women and newborns transfer from level II to level III hospitals were also well described. A specific training is neonatology was created starting in 1990. This organization resulted in an impressive decrease in mortality rates at all levels and still it is the policy we have today.

Gravidez após Colocação de Banda Gástrica para Tratamento da Obesidade Mórbida

Obesity is known to have a negative impact on pregnancy outcome, as it is associated with an increase in the incidence of gestational diabetes, hypertension, preeclampsia, neural tube defects, macrosomia, and late fetal death. Gastric banding is considered an appropriate intervention for morbid obesity when other weight-loss measures are unsuccessful, and this treatment has been shown to be effective in causing a sustainable weight loss. Some women will become pregnant after bariatric surgery, and the nutritional and metabolic challenges brought by gastric banding may have a profound impact on maternal health and pregnancy outcome. The authors report the case of a 27 year old pregnant woman, with a past medical history of gastric banding surgery for morbid obesity. At 18 weeks of gestation, the patient started complaining of severe nausea and vomiting, The situation deteriorated three weeks later when she rapidly developed severe desnutrition, dehydration and early signs of liver and renal failure. Migration of the gastric band was diagnosed, and laparoscopy conducted to remove it. In the day following surgery the patient complained of absent fetal movements, and an intrauterine demise was diagnosed on ultrasound. Pathological examination of the fetus and placenta failed to reveal the cause of death, but no growth restriction was documented, suggesting the occurrence of an acute event.

Hipertiroidismo na Gravidez – um Caso Clinico

Thyroid disease is common in pregnant women.We report a 10 weeks gestation pregnancy with hyperemesis gravidarum, hypertension crisis and hyperthyroidism

Implante Contraceptivo Não Palpável - Estratégias para a sua Localização e Remoção

Overview and Aims: The contraceptive implant is frequently used to provide contraceptive protection over three years. The implant is inserted into the subcutaneous tissue of the upper arm, and should be palpable and easily removed. We evaluated the best imaging strategy for non-palpable implant (Implanon®) localization and removal. Study Design: Retrospective study. Population: A total of 11 women referred to a tertiary care hospital, between October 2009 and January 2012, for localization and removal of their non-palpable implants. Methods: Different localization methods (ultrasound and magnetic resonance imaging) were evaluated for non-palpable rod. Results: Seven of the nonpalpable implants were inserted in a health care center, three in a district hospital and one in a private clinic. In three women, the reasons for requesting removal were the end of the implant validity, two wanted to become pregnant, two had weight gain, one had weight loss, one referred irregular bleeding, one had two implants and one did a hysterectomy. In 81.8% (9) of the women, the implants were identified and localized by ultrasound, and successfully removed. In two patients the implant was not found and therefore not removed. Conclusions: In our study, high resolution ultrasound proved to be a sensitive method in implants localization, being the primary choice for determining the location of nonpalpable implants.
