RESUMO

BACKGROUND: Informing couples about the diagnosis of severe fetal pathologies is part of the daily routine in fetal medicine. This situation is usually complex and can put untrained professionals in an uncomfortable position. The aim of this study was to assess the perception of health care professionals when faced with the need to announce a fetal pathology in order to target their training gaps in this domain. MATERIALS AND METHODS: A questionnaire was created and disseminated on a national level among physicians practicing or collaborating with the multidisciplinary centers of prenatal diagnosis in France. The questionnaire focused on the difficulties encountered by practitioners when announcing fetal pathologies, and their potential interest in simulation sessions regarding the delivery of bad news. RESULTS: 193 participants filled the questionnaire. 65 % report not receiving any theoretical courses in this field during their initial training, 49 % admit feeling uncomfortable when a fetal anomaly needs to be announced, 79.5 % think that role-play could help them, 87.5 % believe that training sessions in communication skills would help improve their methods and 73.1 % support teaching the delivery of bad news by simulation sessions. CONCLUSION: This survey illustrates the significance of announcing a fetal pathology for fetal medicine professionals. Many of them report not being properly trained to cope with this situation and would like to improve with a more practical way of teaching. Simulation would be the ideal educational tool to meet this demand.

RESUMO

Previous epidemiological studies have shown that prenatal exposure to organochlorine pesticides (OCPs) entails a variety of adverse impacts on fetal health, but it is not yet known whether it is associated with risk for orofacial clefts (OFCs). This study of 103 fetuses or newborns with a diagnosis of OFCs (cases) and 103 healthy newborns without malformations (controls) examined whether prenatal exposure to OCPs, as indicated by their concentrations in placental tissue, is a risk factor for OFCs. No differences were found in the median concentrations of OCPs between cases and controls, with exception of o,p'-dichlorodiphenyldichloroethylene, o,p'-dichlorodiphenyldichloroethane, and total o,p'-dichlorodiphenyltrichloroethane (DDTs), whose concentrations were higher in controls than in cases (Ps < 0.05). Although higher concentrations of placental δhexachlorocyclohexane and isodrin were found to be associated with decreased risk for OFCs in logistic regression, no association was observed in the Bayesian kernel machine regression, a novel statistical model in analyzing exposure mixtures. Women who reported periconceptional folic acid supplementation had lower placental concentrations of DDTs than women who did not. In conclusion, no association between levels of OCPs in placental tissue and risk for OFCs was observed in this population. Supplementation with folic acid may help decrease the levels of DDTs in placental tissue, but further studies are needed to confirm this unexpected finding.

RESUMO

In clinical care settings, religiosity may serve as an important source of support for coping with the prenatal diagnosis of fetal abnormalities. This study evaluated the influence of religiosity on the situational coping of 28 pregnant women with fetal abnormalities. The study was approved by the institutional research ethics committee, and the informed consent document was obtained from all participants included in this study. Validated measures of religiosity and situational coping were used to evaluate data collected. Practical religiosity but not intrinsic religiosity correlated positively and significantly with coping scores. However, the severity of the fetal malformations did not correlate significantly with the scores of maternal coping. The results showed that religious practices were associated with improved coping in women diagnosed with fetal abnormalities and should be encouraged in care settings.

RESUMO

OBJECTIVE: to explore written statements found in online discussion boards where parents currently expecting, or with previous experience of expecting, a child with a prenatally diagnosed congenital anomaly communicate about their emotional process from diagnosis to birth. DESIGN: cross-sectional qualitative study of messages in public online discussion boards. SETTING: Swedish public discussion boards about reproductive subjects. SAMPLE: ten pregnant women and eight parents (of children with prenatal diagnoses) who had written 852 messages in five threads in Swedish online discussion boards identified via systematic searches. MEASUREMENTS AND FINDINGS: three phases were identified in the process of moving from the diagnosis to the birth: shock, existential crisis, and life remodeling. The people posting message ('posters') moved from initial shock to existential crisis and, lastly, a phase of remodeling life later in the pregnancy. During the pregnancy, considerable worries about both antenatal and postnatal aspects were expressed. To cope with their situation, the posters distanced themselves from the diagnoses, vented their feelings, sought control, and obtained practical support from friends and relatives. KEY CONCLUSIONS: expectant parents faced with a prenatal diagnosis move from initial shock to a phase of life remodeling and acceptance. Burdened with considerable worries, expectant parents cope with their situation through informational, emotional, and instrumental support from health professionals, family, friends, and peers. IMPLICATIONS FOR PRACTICE: health professionals should make sure that expectant parents feel involved in planning their children's postnatal care, that they are offered sufficient information, and that they have access to emotional and instrumental support structures.

RESUMO

While the immunogenic potential of the vaccination against infectious diseases was extensively shown, data on the safety assessment of recombinant proteins in vaccine formulations administered during pregnancy are still scarce. In the current study, the antigenicity of a vaccine against leishmaniasis (based on Leishmania braziliensis recombinant protein peroxidoxin) during pregnancy and possible maternal reproductive outcomes and fetal anomalies after immunization with a leishmanial vaccine or adjuvant alone (Bordetella pertussis derived MPLA adjuvant) were assessed. Rats were mated and allocated in three groups: Control-rats received saline; Adjuvant-rats received the adjuvant MPLA, and Vaccine-rats received the combination of MPLA and peroxidoxin. The administration was subcutaneously at the dorsal region, three times (days 0, 7, 14 of pregnancy). On day 21 of pregnancy, all rats were bled for biochemical and immunological measurements. The gravid uterus was weighed with its contents, and the fetuses were analyzed. The immunization with peroxidoxin induced a significant production of circulating IgG levels compared to other groups but caused a significant in post-implantation loss (14.7%) when compared to Control (5.0%) and Adjuvant (4.4%) groups. Furthermore, a significantly high rate of fetal visceral anomalies, such as hydronephrosis and convoluted ureter, was also observed in animals that received vaccine when compared to Control or Adjuvant groups. These data indicate the importance of safety evaluation of vaccines during pregnancy and the limited use of peroxidoxin administration during pregnancy. More importantly, the safety monitoring of immunization with MPLA derived from Bordetella pertussis demonstrated no reproductive outcomes associated with adjuvant administration, suggesting its safe use during pregnancy.

RESUMO

Objectives To identify the epidemiological risk factors for congenital anomalies (CAs) and the impact of these fetal malformations on the perinatal outcomes. Methods This prospective cohort study comprised 275 women whose fetuses had CAs. Maternal variables to establish potential risk factors for each group of CA and perinatal outcomes were evaluated. The primary outcome was CA. Secondary outcomes included: fetal growth restriction (FGR); fetal distress (FD); premature rupture of membranes (PROM); oligohydramnios or polyhydramnios; preterm delivery (PTD); stillbirth; cesarean section; low birth weight; Apgar score < 7 at the 1st and 5th minutes; need for assisted ventilation at birth; neonatal infection; need for surgical treatment; early neonatal death; and hospitalization time. Chi-square (χ(2)) test and multilevel regression analysis were applied to compare the groups and determine the effects of maternal characteristics on the incidence of CAs. Results The general prevalence of CAs was of 2.4%. Several maternal characteristics were associated to CAs, such as: age; skin color; level of education; parity; folic acid supplementation; tobacco use; and history of previous miscarriage. There were no significant differences among the CA groups in relation to FGR, FD, PROM, 1-minute Apgar score > 7, and need for assisted ventilation at birth. On the other hand, the prevalence of the other considered outcomes varied significantly among groups. Preterm delivery was significantly more frequent in gastrointestinal tract/abdominal wall defects. The stillbirth rate was increased in all CAs, mainly in isolated fetal hydrops (odds ratio [OR]: 27.13; 95% confidence interval [95%CI]: 2.90-253.47). Hospitalization time was higher for the urinary tract and congenital heart disease groups (p < 0.01). Neonatal death was significantly less frequent in the central nervous system anomalies group. Conclusion It was possible to identify several risk factors for CAs. Adverse perinatal outcomes were presented in all CA groups, and may differ according to the type of CA considered.

Resumo Objetivos Identificar os fatores epidemiológicos de risco para anomalias congênitas (ACs) e o impacto destas malformações fetais sobre os resultados perinatais. Métodos Este estudo de coorte prospectivo compreendeu 275 mulheres cujos fetos tinham ACs. Variáveis maternas para estabelecer potenciais fatores de risco para cada grupo de AC e resultados perinatais foram avaliados. O desfecho primário foi CAs. Os desfechos secundários incluíram: restrição de crescimento fetal (RCF); sofrimento fetal (SF); ruptura prematura de membranas (RPM); oligo-hidrâmnio ou polidrâmnio; parto pré-termo (PPT); morte fetal; parto cesárea; baixo peso ao nascer; índice de Apgar < 7 no 1° e 5° minutos; necessidade de ventilação assistida no momento do nascimento; infecção neonatal; necessidade de tratamento cirúrgico; óbito neonatal precoce; e tempo de internação. Teste de Qui-quadrado (x2) e análise de regressãomúltipla foram aplicados para comparar os resultados entre os grupos e determinar os efeitos das características maternas sobre a incidência de ACs. Resultados A prevalência geral de ACs foi de 2.4%. Várias características maternas foram associadas às ACs, tais como: idade; cor da pele; escolaridade; paridade; suplementação com ácido fólico; tabagismo; e histórico de aborto anterior. Não houve diferenças significativas entre os grupos de ACs com relação à RCF, SF, RPM, índice de Apgar < 7 no 1°minuto e necessidade de ventilação assistida no nascimento. Por outro lado, a prevalência dos demais resultados adversos considerados variou significativamente entre os grupos. O parto pré-termo foi significativamente mais frequente nos casos de defeitos do trato gastrointestinal/parede abdominal. As taxas de óbito fetal foram elevadas em todos os grupos de ACs, principalmente na hidropsia fetal isolada (odds ratio [OR]: 27.13; intervalo de confiança de 95% [IC95%]: 2.90-253.47). O tempo de internação foi maior nos casos de anomalias do trato urinário e nas cardiopatias congênitas (p < 0,01). O óbito neonatal foi significativamente menos frequente no grupo de anomalias do sistema nervoso central. Conclusão Foi possível identificar vários fatores de risco para ACs. Resultados perinatais adversos foram observados em todos os grupos de ACs, e podem diferir de acordo com o tipo de AC considerada.

RESUMO

OBJECTIVE: The disclosure of a diagnosis during pregnancy of a fetal malformation, which is incompatible with life, normally comes completely unexpectedly to the parents. Although a body of international literature has considered the topic, most of it comes from the United States and little has been generated from Europe. This study aims to illuminate the contemporary treatment associated with such diagnoses, regardless of whether parents decide to terminate or continue the pregnancy. DESIGN: a qualitative design was used with data collected by semi-structured interviews and subjected to a thematic analysis. SETTING: the research was conducted in the German speaking areas of Switzerland with data collected from participants in places of their choice. PARTICIPANTS: 61 interviews were conducted with 32 parents and 29 health professionals. FINDINGS: the theme of 'temporality' identified four main time points from the professionals: diagnosis, decision, birth/death, and afterwards. However, in contrast to these, six major themes in this study, primarily generated from parents and extended from receiving the diagnosis until the interview, were identified: shock, choices and dilemmas, taking responsibility, still being pregnant, forming a relationship with the baby, letting go. Although there was concurrence on many aspects of care at the point of contact, parents expressed major issues as gaps between the points of contact. CONCLUSIONS: care varied regionally but was as sensitive as possible, attempting to give parents the space to accept their loss but fulfil legal requirements. A gap exists between diagnosis and decision with parents feeling pressured to make decisions regarding continuing or terminating their pregnancies although health professionals' testimonies indicated otherwise. A major gap manifested following the decision with no palliative care packages offered. During the birth/death of the baby, care was sensitive but another gap manifested following discharge from hospital.

RESUMO

La recomendación de la Organización Mundial de la Salud, en relación al porcentaje de partos que deberían tener vía abdominal es 15%, esto dado por condiciones no prevenibles o patologías materno-fetales que contraindican el nacimiento vía vaginal. En Colombia, la Encuesta Demográfica Nacional de 2010, reporta la realización de cesárea en un 34% de los nacimientos. Una de las indicaciones del parto por vía abdominal, es la mala posición fetal, sin embargo, si está circunstancia es diagnosticada antes del término de la gestación, puede ser manejada con técnicas de la Medicina Tradicional China. Se revisaron los textos clásicos y los estudios publicados recientemente, con relación al uso de Medicina Tradicional China en el manejo de la mala posición fetal, encontrándose que existe suficiente información con relación a la seguridad y efectividad del manejo con moxibustión asociada o no a acupuntura en el punto Vejiga 67 (Zhi yin) para mujeres con gestaciones entre 33 y 35 semanas en ausencia de otro factor de riesgo materno o fetal.

RESUMO

The aim of this study was to evaluate the effect of Himatanthus sucuuba on the maternal reproductive outcome and fetal anomaly incidence in rats. Pregnant rats were randomly divided into three experimental groups as follows: Control = treated with water (vehicle), treated 250 = treated with H. sucuuba at dose 250 mg/kg, and treated 500 = treated with H. sucuuba at dose 500 mg/kg. The rats were orally treated, by gavage, with H. sucuuba or vehicle (water) during preimplantation and organogenic period (from gestational day 0-14). At day 21 of pregnancy, all rats were killed to obtain maternal-fetal data. The treatment with H. sucuuba at dose of 250 mg/kg caused reduction in placental efficiency and an increase preimplantation loss rate and placenta weight compared with the control. The treated 500 group presented a significant decrease in maternal weight gain, maternal weight gain minus gravid uterus weight, fetal weight, and placental efficiency compared with the control. In this group, there was a decrease in body weight at day 20 of pregnancy and metacarpus ossification and an increase in the preimplantation loss rate and skeletal anomalies compared with other groups. Himatanthus sucuuba extract caused intrauterine growth restriction, preimplantation loss, and developmental delay in the high doses tested.

RESUMO

CONTEXT AND OBJECTIVE: Anencephaly is considered to be the most common type of neural tube defect. Our aim was to assess the clinical and gestational features of a cohort of fetuses with suspected anencephaly. DESIGN AND SETTING: Population-based retrospective cohort study in a referral hospital in southern Brazil. METHODS: The sample consisted of fetuses referred due to suspected anencephaly, to the Fetal Medicine Service of Hospital Materno Infantil Presidente Vargas, between January 2005 and September 2013. Clinical, radiological, pathological and survival data were gathered. RESULTS: Our sample was composed of 29 fetuses. The diagnosis of suspected anencephaly was made on average at 21.3 weeks of gestation. Seven fetuses had malformations that affected other organs, and these included oral clefts (n = 4) and congenital heart defects (n = 2). In 16 cases, there was termination of pregnancy (n = 12) or intrauterine death (n = 4). Regarding those who were born alive (n = 13), all of them died in the first week of life. After postnatal evaluation, the diagnosis of anencephaly was confirmed in 22 cases (75.9%). Other conditions included amniotic band disruption complex (6.9%), microhydranencephaly (6.9%), merocrania (3.4%) and holoprosencephaly (3.4%). CONCLUSIONS: Different conditions involving the cranial vault may be confused with anencephaly, as seen in our sample. However, these conditions also seem to have a poor prognosis. It seems that folic acid supplementation is not being properly performed. .


CONTEXTO E OBJETIVO: A anencefalia é considerada o tipo mais comum de defeito de fechamento do tubo neural. Nosso objetivo foi avaliar as características clínicas e gestacionais de uma coorte de fetos com suspeita de anencefalia. TIPO DE ESTUDO E LOCAL: Estudo de coorte retrospectivo de base populacional em um hospital de referência no sul do Brasil. MÉTODOS: A amostra foi composta por fetos encaminhados por suspeita de anencefalia ao Serviço de Medicina Fetal do Hospital Materno Infantil Presidente Vargas, no período de janeiro de 2005 a setembro de 2013. Foi realizada coleta de dados clínicos, radiológicos, patológicos e de sobrevida. RESULTADOS: Nossa amostra foi composta por 29 fetos. A suspeita do diagnóstico de anencefalia foi realizada em média com 21,3 semanas de gestação. Sete fetos apresentavam malformações que afetavam outros órgãos, e incluíram fendas orais (n = 4) e defeitos cardíacos congênitos (n = 2). Em 16 casos houve interrupção da gravidez (n = 12) ou morte intrauterina (n = 4). Daqueles que nasceram vivos (n = 13), todos morreram na primeira semana de vida. Após a avaliação pós-natal, o diagnóstico de anencefalia foi confirmado em 22 casos (75,9%). Outras condições incluíram o complexo disruptivo de banda amniótica (6,9%), microhidranencefalia (6,9%), merocrania (3,4%) e holoprosencefalia (3,4%). CONCLUSÕES: Diferentes condições que envolvem a calota craniana podem ser confundidas com a anencefalia, como verificado em nossa amostra. No entanto, estas também parecem ter um prognóstico pobre. A suplementação com ácido fólico parece não estar sendo realizada de forma adequada. .

RESUMO

OBJECTIVE: To investigate the molecular mechanism of Hoxd13-mediated congenital malformations in rat embryos. METHODS: SD female rats were mated with male rats in a 1:1 mating scheme. Thirty pregnant female rats were randomly divided into three groups: the control group receiving a normal diet, the model group receiving a vitamin A-deficient diet, and the treatment group receiving a vitamin A-deficient diet supplemented with pcDNA-Hoxd13. The expression of Hoxd13 mRNA and protein in normal embryonic tissue and congenital malformations was determined by RT-PCR and Western blot analysis. At day 20, rats were dissected, and the fetal weight, body and tail length, and the number of live births, absorbed fetus, and stillbirth in each group were recorded. Wnt and Slim1 expression was detected by RT-PCR and Western blot analysis. ß-catenin and c-myc expression was also quantified by Western blot analysis. RESULTS: The expression of Hoxd13 mRNA and protein in congenital malformations was significantly lower compared with normal embryonic tissue (P<0.01). The administration of exogenous Hoxd13 in the treatment group markedly increased the fetal weight, body and tail length (P<0.05), improved the embryonic survival rate, and reduced the embryonic resorption rate and stillbirth rate (P<0.05). Exogenous Hoxd13 markedly promoted the expression of Wnt2, Wnt5a, Wnt7b and Slim1 protein and mRNA (P<0.01), and the expression of ß-catenin and c-myc protein in congenital malformations (P<0.01). CONCLUSION: Hoxd13 expression was decreased in rat embryos with congenital malformations. The administration of exogenous Hoxd13 alleviated fetal malformation probably through stimulation of Slim1 expression and Wnt/ß-catenin signaling pathway.

RESUMO

Religion plays a significant role in a patient's bioethical decision to have an abortion as well as in a country's abortion policy. Nevertheless, a holistic understanding of the Islamic position remains under-researched. This study first conducted a detailed and systematic analysis of Islam's position towards abortion through examining the most authoritative biblical texts (i.e. the Quran and Sunnah) as well as other informative factors (i.e. contemporary fatwas, Islamic mysticism and broader Islamic principles, interest groups, and transnational Islamic organizations). Although Islamic jurisprudence does not encourage abortion, there is no direct biblical prohibition. Positions on abortion are notably variable, and many religious scholars permit abortion in particular circumstances during specific stages of gestational development. It is generally agreed that the least blameworthy abortion is when the life of the pregnant woman is threatened and when 120 days have not lapsed; however, there is remarkable heterogeneity in regards to other circumstances (e.g. preserving physical or mental health, foetal impairment, rape, or social or economic reasons), and later gestational development of the foetus. This study secondly conducted a cross-country examination of abortion rights in Muslim-majority countries. A predominantly conservative approach was found whereby 18 of 47 countries do not allow abortion under any circumstances besides saving the life of the pregnant woman. Nevertheless, there was substantial diversity between countries, and 10 countries allowed abortion 'on request'. Discursive elements that may enable policy development in Muslim-majority countries as well as future research that may enhance the study of abortion rights are discussed. Particularly, more lenient abortion laws may be achieved through disabusing individuals that the most authoritative texts unambiguously oppose abortion, highlighting more lenient interpretations that exist in certain Islamic legal schools, emphasizing significant actors that support abortion, and being mindful of policy frames that will not be well-received in Muslim-majority countries.

RESUMO

Exposure to arsenic via drinking water is considered as a worldwide problem. Studies have shown that arsenic exposure during pregnancy affects embryogenesis and offspring development in rats and mice. Zinc as a micronutrient regulates many physiological functions, including an antioxidative role under various toxic conditions. However, studies on the perinatal protective effect of zinc on offspring need further attention. The present study was designed to evaluate the potential protective role of zinc in mitigating the adverse effects in the offspring of arsenic exposure during pregnancy. The arsenic (40mg/kg body weight) and zinc (4% w/v) doses formed the only drinking fluid source for the experimental groups of dams during the perinatal period of the experiment. The early development of sensory motor coordination reflexes together with morphological development in the male pups was measured during the weaning period. In adolescence, the offspring were tested for their motor behavior. The enzyme γ-glutamyl transferase (γ-GT) and the oxidative stress indices like reduced glutathione (GSH) and lipid peroxidation (TBARS) were also estimated in the serum of the young adult male mice. Perinatal arsenic exposure caused depletion in body weight gain, delay in morphological development and retardation in the development of all sensory motor reflexes of the pups. In young adults, significant decrease in motor behavior with significant decrease in GSH level in the serum was observed. On the other hand, γ-GT and TBARS were significantly increased in the serum due to arsenic treatment. However, animals exposed to arsenic in the presence of zinc showed a remarkable ameliorating effect of zinc on all observed teratological and biochemical arsenic toxicity in male offspring. It was observed that zinc has an antioxidative role in the perinatal toxicity of arsenic. It is concluded from the present study that zinc consumed during the perinatal period of pregnancy can ameliorate the possible toxicities of arsenic exposure in the offspring by acting as an ameliorative supplement.

RESUMO

This reflection is an anonymised account of a feticide which I witnessed as a second year midwifery student. Having cared for this woman I found myself unable to put it out of my mind until I wrote it down and asked my mentor and a lecturer to help me debrief. It describes the events themselves as well as my feelings, and uses the Gibbs reflective cycle (Gibbs 1988) to demonstrate insights into my own learning and future development as a midwife.

RESUMO

OBJECTIVE: to describe men's and women's experiences of deciding whether to tell people in their social network, including their children, about their pregnancy loss following a termination for fetal abnormality. DESIGN: secondary analysis of qualitative narrative interview data informed by a critical realist approach. SETTING: respondents were recruited throughout the United Kingdom and interviewed at home between 2004 and 2005. PARTICIPANTS: twenty-eight women and nine men who had ended a pregnancy diagnosed with a fetal abnormality and who talked about disclosing or not disclosing the termination to others. FINDINGS: few respondents reported having any advice or information about whether or how to disclose their termination. None said they completely concealed their decision from adults in their social network; most said they disclosed selectively, telling close friends and family they had terminated and acquaintances they had miscarried. Most respondents reported telling their young children that the baby had died but did not reveal that they had chosen to end the pregnancy. A minority had not told their existing offspring about the pregnancy loss. Common reasons given for (partially) concealing a termination were: guilt over the decision; to avoid being judged; and to protect other people's feelings. Common reasons for disclosure were: others knew of the pregnancy; needing time off work; needing practical help and/or emotional support during diagnosis and termination; and wanting recognition of their loss. Positive consequences of disclosure were said to be getting more support and less criticism than expected; negative consequences included not getting the anticipated support and empathy; and encountering disapproval. Some respondents felt that concealing their pregnancy loss from their children had resulted in their confusion over the cause of their parents' distress. Some men said they found it hard to access emotional support from their social networks because of expectations about how men 'should' deal with emotions. KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: midwives have to make difficult judgements about what, how and when to provide information when trying to support and advise parents who have ended a pregnancy due to fetal abnormality. Further education and training in this area could be of benefit. Midwives could signpost parents to existing sources of advice around disclosure, taking into account parents' individual preferences, help parents to consider the potential implications of disclosure and concealment and different ways of disclosing. They could also recommend alternative sources of emotional support, bearing in mind that men in particular may find it harder to access support from their social networks.

RESUMO

BACKGROUND AND PURPOSE: Periventricular nodular heterotopia are common malformations of cortical development that are associated with many clinical syndromes and with many different neuroimaging phenotypes. The purpose of this study was to determine whether specific malformation phenotypes may be related to location, side, or number of PNH as assessed by MR imaging. MATERIALS AND METHODS: MR images of 200 patients previously diagnosed with PNH were retrospectively analyzed. PNH were classified according to their location along the ventricles (anterior, posterior, or diffuse), side (unilateral or bilateral), and number of nodules (<5, 6-10, or >10). The cerebrum, brain stem and cerebellum were analyzed to assess associated anomalies. Associations between PNH location and the presence of other anomalies were tested by using Fisher exact test and χ2 test. RESULTS: Posterior PNH were significantly associated with malformations of the cerebral cortex, diminished white matter volume, and mid-/hindbrain anomalies. Diffuse PNH were associated with diminished white matter volume, callosal "anomalies," and the presence of megacisterna magna. Unilateral PNH were strongly associated with cortical malformations. CONCLUSIONS: Certain malformation complexes are associated with PNH in specific locations: posterior PNH with cerebral cortical and mid-/hindbrain malformations and diffuse PNH with callosal anomalies and megacisterna magna. Knowledge of these associations should allow more directed analyses of brain MR imaging in patients with PNH. In addition, knowledge of these associations may help to direct studies to elucidate the causes of these malformation complexes.
