Denial of pregnancy: population based study

Denial of reproductive potential: a predictor of unperceived pregnancy in an Austrian neonaticide sample

PURPOSE

This study aims to describe the phenomenon of unperceived pregnancy followed by neonaticide with a focus on the lack of awareness of reproductive potential in an Austrian sample.

METHODS

An explorative comparative study of neonaticide cases with single and repeat perpetrators was conducted using nationwide register-based data from 1995 to 2017. A total number of 55 cases out of 66 were included in the analysis. A standardized coding sheet was used and calculations were performed.

RESULTS

48 women gave birth to 101 children, of which 55 were killed, 23 children lived out of home care and 23 lived with the perpetrator We found a higher fertility rate in both neonaticide perpetrators in the single (1,9) and the repeat group (4,25) in comparison to the general population (1,4). The use of contraception was only 31% among neonaticide perpetrators, deviating substantially from the general Austrian population age group (16-29yrs) which used contraception in 91%. The neonaticide perpetrators used an effective contraception method (pearl-index < 4) in only 2%, whereas 20% of the general population did so. The number of unperceived pregnancies was high in both groups (50/55) 91%.

CONCLUSION

Future case reports and forensic evaluations should take reproductive behavior into account, as it may offer valuable insights into the events leading up to neonaticide. Our findings suggest that denial of reproductive potential often precedes unperceived pregnancies. In the Austrian cohort, women who experienced unperceived pregnancies resulting in unassisted births and subsequent neonaticide showed a low prevalence of contraceptive use. This is particularly noteworthy given that the primary motive for neonaticide is unwanted pregnancy.

Restorative justice in a case of traumatic birth following an unperceived pregnancy

PURPOSE

Pregnancy can be denied or better "unperceived" by women in up to 1:300 pregnancies and poses the mother and her unborn at high risk when an unassisted birth follows. The importance of recognizing unperceived pregnancy and the risk of unassisted births for both mothers and their babies are described.

METHODS

Description of a case of unperceived pregnancy and traumatic unassisted birth.

RESULTS

A pregnant woman was not diagnosed in a clinic despite being at the verge of giving birth. She was turned away, was on her way to another hospital, and gave birth in a toilet in a dissociative state. The baby survived, but the mother was declared guilty of attempted manslaughter and received a 6-year prison sentence. The expertise of a perinatal psychiatrist reversed the verdict and the court apologized to the mother, now living with her son.

CONCLUSIONS

This case shows the severe consequences when pregnancy and labor are not recognized by health professionals. The reversal of the original sentence is considered a pioneer case of restorative justice in the context of unperceived pregnancy and obstetric violence. Health providers and courts need to be informed by perinatal mental health professionals about the impact of unperceived pregnancy and obstetric violence.

Pregnancy Denial: Toward a New Understanding of the Underlying Mechanisms

PURPOSE OF REVIEW

Pregnancy denial is the lack of awareness of being pregnant. The aim of the review is to understand why the affected women do not recognize the signs of pregnancy.

RECENT FINDINGS

Twelve case reports of pregnancy denial were published in the last ten years. While in five cases the women had an underlying mental disorder, the rest of the cases involved women who either exhibited no physical symptoms or perceived themselves to be not pregnant despite the symptoms (i.e., repression mechanisms). Pregnancy denial is considered to be a pathological issue, a likely consequence of trauma, the wish to not have a child, or a psychiatric problem. However, it appears that the majority of cases cannot be linked to any of the above reasons. We argue, therefore, that, in most cases, pregnancy denial is not associated with mental or physiological problems. Under certain circumstances, it can affect any woman.

Denial of pregnancy and neonaticide: A historical overview and case report

While denial of pregnancy and neonaticide are rare, they are potentially associated and share some risk factors. Neonaticide has been proposed as the extreme outcome of a denial of pregnancy. However, the process leading to such a possible outcome is not yet fully understood. The primary goal of this essay is to examine the various definitions and ambiguities surrounding the denial of pregnancy. The case of a young woman with a history of two denied pregnancies with diverse characteristics and outcomes, the latest of which resulted in neonaticide, is then reported and examined. A forensic psychiatric evaluation was also performed to reconstruct the woman's mental state at the time of the crime. The forensic pathological analysis of the newborn, abandoned near the sea while still alive, is described. The victim's body showed signs of shaken baby syndrome. We contend that differing levels of awareness during a denial of pregnancy might not be predictive of the potential delivery outcome in terms of threat to the newborn's survival, according to the forensic pathological and psychopathological data of the current case. Early identification of women affected by denial of pregnancy who pose a danger of committing infanticide is hampered by both intrinsic traits (dissimulation, unawareness, low propensity to seek assistance) and environmental factors (isolation, low socioeconomic level, poor education.). A previous history of denial of pregnancy should activate health and support services to reduce the potential risks for the mother and the child.

A case report involving the experience of pervasive pregnancy denial: detailed observation of the first 12 postpartum weeks

BACKGROUND

Pervasive pregnancy denial is a rare condition associated with distress and unassisted delivery.

CASE PRESENTATION

The case involves a 38-year-old woman (NN), with two older children (ages 8 and 11), who was unaware, until delivery, that she had been pregnant. The case is discussed in the context of a 12-week observation of postpartum mood, stress, and mother-child attachment. NN and other 558 non-depressed women (mean age 32.41 years) were selected from the pool of participants in the RIPOD (risk of postpartum depression) study. All participants were recruited within 1-6 days of delivery. In addition to surveying depressed mood at childbirth, remote assessments of mood, mother-child attachment, and perceived stress were conducted at 3, 6, 9, and 12 weeks postpartum. Every other day, the participants also reported their current perceived stress levels based on a scale from 1 (low) to 10 (high). During the entire period of postpartum observation, NN reported no symptoms on the Edinburgh Postpartum Depression Scale, similar to only 1.6% of the sample, no stress as 0.7% of the sample, and above-average mother-infant bonding akin to only 4.6% of the sample. Her daily stress levels showed no disturbance, which was the case for only 3.32% of the total sample. On the day of delivery, NN reported a stress level of 1 (the minimum possible level), which was reported by only 4.2% of the total sample. However, NN reported the experience of delivery to be traumatic given that the child had fallen to the floor.

CONCLUSION

The experience of a denied pregnancy did not appear to disturb NN at any time point, not even on the day of delivery. Compared to NN, the other non-depressed participants reported wide fluctuations in stress levels during the observation period. NN did not report any risk factors for denied pregnancy. Thus, she belonged neither to any group of typical pregnancy deniers, as reported in the literature, nor to a typical postpartum group. We postulate, therefore, that the extent to which pregnancy denial can be deemed a normal variation, unrelated to a psychological or physiological condition, depends largely on personal traits.

Towards a new understanding of pregnancy denial: the misunderstood dissociative disorder

Pervasive pregnancy denial is a misunderstood reproductive anomaly which compromises the health of both mother and the developing fetus. Because in extreme cases, the death of the neonate at the hands of his/her mother has criminal repercussions, research has attempted to explain the origins of this clinical phenomenon. The purpose of this review is to analyze the evolution of understanding the association between pregnancy denial and neonaticide. This paper identifies the consistent similarities in symptom presentation, particularly dissociation, when a denied pregnancy ends with the death of the newborn. The common thread across the progression of the literature over time serves as a foundation for considering the development of diagnostic criteria for future inclusion in the Diagnostic and Statistical Manual of Mental Disorders. This paper reviews the seminal research from 1969 to current research up to 2020 addressing pregnancy denial and its connection to neonaticide. Peer reviewed and published articles related to key terms around "pregnancy denial," "pregnancy concealment," "neonaticide," and "dissociation" were retrieved from major databases such as PubMed, PsychINFO, JSTOR, ProQEST, ScienceDirect, and Google Scholar. Reference lists of relevant articles were also scanned to search for further papers pertaining to similarities in symptom presentation across demographic profiles. Papers were excluded if they were not available in English, or if they did not contribute to identifying consistencies in clinical presentation when a pregnancy is denied. There are clear repetitive markers that occur across studies which pertain not only to the frequent absence of certain expected indicators of pregnancy, (i.e. no morning sickness, weight gain, or sensations of fetal movement), but also the misattribution of pregnancy-related symptoms, and the consistent experience of a dissociative episode while giving birth that can unintentionally result in neonaticide. This paper concludes that dissociation is a consistently seen symptom in pervasive pregnancy denial. Dissociation, in addition to other commonly seen symptoms across cases, suggests specific diagnostic criteria that lend themselves to inclusion in the Diagnostic and Statistical Manual of Mental Disorders.

Thinking Outside the Box

Clinical decision-making process is very complex and influenced by multiple aspects. As diagnosis likelihood assessment is often based on intuitive thinking, data misinterpretation, and diagnostic errors may commonly occur. We present a peculiar clinical case of a 27-year-old obese woman admitted to the emergency department after an inaugural episode of seizures. She had an oncologic disease. She was febrile and hypertensive at first evaluation. The report evolves around the diagnostic assessment, hampered by incongruent anamneses, incorrect data interpretation, and a pinch of clinical obstination, which nearly culminated in two deaths. Then, we discuss the series of biases that have confused the physicians. The only way to escape the intuitive thinking trap is to be humbly aware of our own thinking method’s limitations and to learn about the biases that often lead us into errors. Sometimes, thinking outside the box is the key.

Denial of Pregnancy in a Patient With a History of Pseudocyesis

Denial of pregnancy is a condition in which a pregnant patient does not believe she is pregnant. This case describes a 23-year-old Caucasian female, with a past psychiatric history of pseudocyesis, stimulant use disorder, and schizophrenia, who was admitted to the inpatient psychiatric unit for the treatment of psychosis, suicidal thoughts, and homicidal ideation. During her hospitalization, an intrauterine pregnancy was confirmed with three serum quantitative human chorionic gonadotropin (hCG) levels and a transabdominal ultrasound. Despite definitive evidence of pregnancy, the patient reported it was impossible she was pregnant and stated she had not had intercourse for more than a year. The patient was treated with IM haloperidol decanoate and PO haloperidol. Care was coordinated with the obstetrics team to ensure the patient and her fetus received adequate prenatal care. After acute stabilization, the patient was discharged with close follow-up. This case presentation describes one of the few documented cases of pregnancy denial in a patient with a history of pseudocyesis. Additionally, this case highlights the ethical issues associated with the treatment of pregnancy denial patients. Additional studies are necessary to fill in the gaps in the literature on this unique condition.

Unexpected delivery: a case report of cryptic pregnancy in Nigeria

The etiology of cryptic pregnancy has not been fully elucidated and there exist misconceptions about this phenomenon in our contemporary Nigerian society. This case presents the first case report of cryptic pregnancy in sub-Saharan Africa. A case of a 19 year old overweight female student who presented to the sick bay at 01: 30 hours with a 3-day history of lower back pain, abdominal discomfort and constipation. At the sick bay the general practitioner on call asked if she was pregnant and she vehemently said no, recounting that she sees her menstruation regularly. Abdominal examination however, revealed a gravid uterus of about 36 weeks and vaginal examination showed a fully dilated cervix. She was surprised, terrified and confused and only remembered having unprotected sexual intercourse many months earlier. Barely two hours later, she gave birth via spontaneous vaginal delivery, to a live female infant at 03: 14 hours. This case emphasizes the need for general practitioners and specialists in sub-Saharan Africa to be aware of the phenomenon of cryptic pregnancy, which involves women not being conscious of their gravid state until final weeks of gestation or at delivery, to reduce neonatal and maternal complications.

Prenatal and Perinatal EMDR Therapy: Early Family Intervention

This article discusses the integration of eye movement desensitization and reprocessing (EMDR) therapy with a family therapy treatment, which was designed for treating mothers and their babies from conception through the first year of life. The Calming Womb Family Therapy Model (CWFTM) is a multidisciplinary, Integrative, early intervention approach. Its foundations originate from Murray Bowen's family model of understanding the individual in the context of their families as emotional interactive systems; Selma Fraiberg's psychodynamic work and psychoeducational interventions with mothers and infants to resolve maternal trauma and transference reactions to their babies followed by educational guidance in infant development through the first year of their lives; and EMDR therapy. EMDR therapy can improve internal resources for expectant mothers; monitor their levels of psychological distress; and enable them to access and process traumatic memories, other adverse life experiences, recent stressors, and pre-perinatal concerns and bring them to adaptive resolution. EMDR therapy can also help pregnant mothers develop imaginal templates of future events that incorporate in utero developmental prenatal education and deepen their bonds with their babies. The pre-perinatal psychotherapist's knowledge of infant development and capacity for interpersonal warmth, affect tolerance, somatic resourcing, reflective stance, and relational attunement can provide a fertile ground for the expectant mother and womb baby relationship and enriching life together. The ultimate goal is to conceive and rear healthy children.

Assessment of neonaticide in the setting of concealed and denied pregnancies

It is known that concealed and denied pregnancy are both associated with increased health risks to the mother and infant. Whilst there is literature surrounding management and safeguarding in these instances, we are not aware of a case review of post-mortem findings in infants with a history of concealed or denied pregnancy. We performed a retrospective review of all coronial post-mortems performed between 2003 and 2018 on infants and fetuses with a history of concealment or denial of pregnancy. Maternal demographics, delivery information, post-mortem findings and results of ancillary investigations were analyzed. Twenty cases (1.8% of total coronial workload in the period of the study) were included. Four women admitted to concealing their pregnancy, eleven denied their pregnancy and in the remaining five cases the bodies of the infants had been abandoned and the mother was not traceable. The bodies of these infants were found in waste disposal sites, wooded areas and in a drainpipe. Only six infants in total were judged to have survived delivery, all others were stillborn or unascertained. Perinatal hypoxia, large subdural hemorrhage and congenital pneumonia were the reported causes of death in those infants that were liveborn. In one case there was suspicion of neonaticide. Concealment and denial of pregnancy occur in a wider demographic than perhaps anticipated and is not limited to teenage primigravids. Mothers with concealed and denied pregnancy hid the body of their deceased infant out of fear of prosecution. In many circumstances, viability at birth cannot be ascertained.

Foetal abuse

Pregnancy and motherhood are often presented as natural and unproblematic for women. The fact that there are some women who engage in violent behaviour towards their unborn child suggests that motherhood is not as unproblematic as we are led to believe. This paper presents six previously unpublished cases of foetal abuse that is physical assaults on the foetus by the mothers themselves, and examines how the prevailing myth of the good mother might be further endangering mothers and their unborn children. So far, the research suggests there are some common, possibly co-occurring, features that might be an antecedent to foetal abuse: unplanned pregnancies, prior mental health issues in the mother, trauma, pregnancy denial up to 20 weeks or until birth, and ideation of harm correlated to in utero movements.

Denial of Pregnancy: Psychopathology and Clinical Management

Denial of pregnancy (DOP) is a challenging condition with poorly understood psychopathology. DOP is reported to be associated with problems such as severe psychological conflicts, obstetric complications, risks to the newborn, and difficulties in bonding with the infant. In this paper, we present and discuss the clinical manifestations of a severe form of DOP that lasted until the time of delivery with resultant multifaceted complications. Our paper highlights the severity of psychopathology and the need for coordinated management. Descriptions from different cultural backgrounds would improve the conceptual understanding of DOP.

Acute dissociative reaction to spontaneous delivery in a case of total denial of pregnancy: Diagnostic and forensic aspects

This article presents the history of a 21-year-old female college student with total denial of pregnancy who experienced an acute dissociative reaction during the spontaneous delivery at home without medical assistance where the newborn died immediately. Psychiatric examination, self-report questionnaires, legal documents, and witness reports have been reviewed in evaluation of the case. Evidence pointed to total denial of pregnancy, that is, until delivery. The diagnoses of an acute dissociative reaction to stress (remitted) and a subsequent PTSD were established in a follow-up examination conducted 7 months after the delivery. Notwithstanding the inherently dissociative nature of total denial of pregnancy, no other evidence has been found about pre-existing psychopathology. For causing the newborn's death, the patient faced charges for "aggravated murder," which were later on reduced into "involuntary manslaughter." Given the physical incapacity to perform voluntary acts due to the loss of control over her actions during the delivery, and the presence of an acute dissociative reaction to unexpected delivery, the legal case represents an intricate overlap between "insanity" and "incapacitation" defenses. The rather broad severity spectrum of acute dissociative conditions requires evaluation of the limits and conditions of appropriate legal defenses by mental health experts and lawyers. Denial of pregnancy as a source of potential stress has attracted little interest in psychiatric literature although solid research exists which documented that it is not infrequent. Arguments are presented to introduce this condition as a diagnostic category of female reproductive psychiatry with a more neutral label: "unperceived pregnancy."

‘Om Langs Die Pad Te Kraam’: A Feminist Psychoanalytic Perspective on Undisclosed Pregnancy

This article focuses on the phenomenon of pregnant women not acknowledging their pregnancies. Such women typically enter the health care system at a late stage and thus get little or no prenatal care. The phenomenon of undisclosed pregnancy is explored by focusing on two case studies of pregnant research participants in a project concerned with the psychological distress of female farm workers in the Western Cape. These two pregnant women were interviewed for a total of ten hours about topics such as psychological distress and well-being, coping and resilience, family and personal history, physical health, interpersonal relationships, reproductive issues (specifically pregnancy and motherhood), and sexuality and body, but did not reveal to their interviewers that they were pregnant. Follow-up interviews were conducted with the participants in an attempt to form a psychological understanding of their failure to disclose their pregnancies during the interviews. In the follow-up interviews, it became clear that the participants also did not reveal that they were pregnant to their families, their friends, their employers, or any health care workers. The interview data suggested that these two participants construed pregnancy as something to feel guilty, ashamed, and anxious about. Their conscious or unconscious response to this material bodily event was to not recognise or acknowledge it, neither to others nor to themselves. This finding is analysed in the context of the literature concerning the subjective experience of and psychological responses to pregnancy, with specific reference to reports of ‘motivated unawareness’ or ‘denial of pregnancy’ in the pregnancy literature. The question of how to understand the participants' experiences and response to pregnancy is then analysed within a postmodern paradigm, using a feminist psychoanalytic perspective.

From Crime to Disease: Laws on Infanticide in the Modern Era

This is the third of three papers investigating the legislative history concerning infanticide. After Antiquity and the Middle Ages, this paper focuses on legislative reforms during the last 400 years. Despite dreadful punishment, the practice remained frequent until safe abortion became available. In the 17th century, the rate of executions of women for this crime was 1 per 100,000 inhabitants. The actual incidence greatly exceeded this figure. The death penalty failed to deter, and punishing fornication promoted rather than prevented infanticide. Well into the 18th century, severely malformed infants were killed. The lung flotation test, albeit unreliable, was used to save the mother from the death penalty. When the motives for infanticide - poverty, shame, despair, and preserving honour - became understood in the late 18th century, the image of the 'child murderess' changed, and infanticide shifted from constituting a capital crime to a privileged delict. Illegitimate pregnancy was no longer punished, and lying-in hospitals for pregnant unmarried women and foundling hospitals for their children were established. Specific infanticide laws were issued in Prussia in 1756, Britain in 1803, and France in 1811. Once psychosis and denial of pregnancy became understood, severe penalties were no longer issued. The justifications for lenient legislation included social circumstances, difficult proof, and curtailed protection of the newborn due to its illegitimacy, helplessness, and diminished awareness. Thoughts on the limited right to live of newborn infants are still hampering ethical decisions when the beginning and end of life are near each other.

Psychosomatic disorders of gravida status: false and denied pregnancies

OBJECTIVE

The authors review the literature on two dramatic psychosomatic disorders of reproduction and offer a potential classification of pregnancy denial.

METHOD

Information on false and denied pregnancies is summarized by comparing the descriptions, differential diagnoses, epidemiology, patient characteristics, psychological factors, abdominal tone, and neuroendocrinology. Pregnancy denial's association with neonaticide is reviewed.

RESULTS

False and denied pregnancies have fooled women, families, and doctors for centuries as the body obscures her true condition. Improvements in pregnancy testing have decreased reports of false pregnancy. However, recent data suggests 1/475 pregnancies are denied to 20 weeks, and 1/2455 may go undiagnosed to delivery. Factors that may contribute to the unconscious deception include abdominal muscle tone, persistent corpus luteum function, and reduced availability of biogenic amines in false pregnancy, and posture, fetal position, and corpus luteum insufficiency in denied pregnancy. For each condition, there are multiple reports in which the body reveals her true pregnancy status as soon as the woman is convinced of her diagnosis. Forensic literature on denied pregnancy focused on the woman's rejection of motherhood, while psychiatric studies have revealed that trauma and dissociation drive her denial.

CONCLUSIONS

False pregnancy has firm grounding as a classic psychosomatic disorder. Pregnancy denial's association with neonaticide has led to misleading forensic data, which obscures the central role of trauma and dissociation. A reappraisal of pregnancy denial confirms it as the somatic inverse of false pregnancy. With that perspective, clinicians can help women understand their pregnancy status to avoid unexpected deliveries with tragic outcomes.

Not your average birth: considering the possibility of denied or concealed pregnancy

A 23-year-old woman presented to the emergency department (ED) with a 3-day history of lower back pain. She had seen her general practitioner 2 days previously who prescribed trimethoprim for a confirmed urinary tract infection. Routine admission observations showed she was tachycardic, tachypnoeic and slightly hypotensive but non-feverish with normal oxygen saturations. Her urine sample revealed that she was pregnant but was otherwise negative. The patient maintained that she was unaware she was pregnant. She was reviewed by an ED staff grade who was suspicious of a ruptured ectopic pregnancy. She was subsequently referred to the obstetrics and gynaecology registrar who on examination found she had a gravid uterus and vaginal examination revealed that her cervix was 8 cm dilated. The patient was very promptly admitted onto the labour ward for further assessment. She gave birth to a live male infant in the early hours of the next morning.

Delayed pregnancy testing and second-trimester abortion: can public health interventions assist with earlier detection of unintended pregnancy?

BACKGROUND

Delayed pregnancy testing has been associated with presentation for abortion in the second trimester. Little is known about acceptability of potential interventions to hasten pregnancy recognition.

STUDY DESIGN

A total of 592 women presenting for abortion at six clinics in the United States completed surveys on contraceptive use, risk behavior, timing of first pregnancy test and interest in interventions to speed pregnancy recognition and testing.

RESULTS

Forty-eight percent of women presenting for second-trimester abortion delayed testing until at least 8 weeks. In multivariate analysis, women who often spotted between periods had higher odds of delaying pregnancy testing [odds ratio (OR) 2.7, 95% confidence interval (CI) 1.04-6.94]. Women who often missed periods had higher odds of second-trimester abortion (OR 2.1, 95% CI 1.34-3.13). The majority (64%) of women were not aware of a fertile time in the menstrual cycle; these women had higher odds of second-trimester abortion (OR 2.0, 95% CI 1.21-3.37). Ninety-four percent of women expressed interest in at least one potential intervention to help recognize pregnancy earlier.

CONCLUSIONS

While there was near-universal interest in earlier pregnancy recognition, no single proposed intervention or scenario was endorsed by the majority. Improving sexual health awareness is an important consideration in future efforts to expedite pregnancy testing.

IMPLICATIONS

We found near-universal interest in earlier pregnancy recognition, though no single proposed intervention or scenario garnered majority support. Based on our findings, the concept of improving sexual health awareness through education should be incorporated in the development of future strategies to hasten recognition of unintended pregnancy.

Analysis of the relationship between neonaticide and denial of pregnancy using data from judicial files

OBJECTIVES

Using judicial files on neonaticides, (1) to examine the frequency of the association between neonaticide and denial of pregnancy; (2) to assess the accuracy of the concept of denial of pregnancy; (3) to examine its usefulness in programs to prevent neonaticides.

METHODS

Quantitative and qualitative analyses of data collected from judicial files during a population-based study carried out in 26 courts in 3 regions of France over a 5-year period.

RESULTS

There were 32 cases of neonaticides identified; 24, perpetrated by 22 mothers, were solved by police investigation. Aged 26 years on average, the mothers had occupations that resembled those of the general population and 17 had jobs, 13 were multiparous and 11 lived in a couple relationship. No effective contraception was used by women in 20 cases. Psychopathology was rare but mothers shared a personality profile marked by immaturity, dependency, weak self esteem, absence of affective support, psychological isolation and poor communication with partners. No pregnancy was registered nor prenatal care followed. Two (perhaps 3) pregnancies were undiscovered until delivery. No typical denial of pregnancy was observed in the other cases. Pregnancies were experienced in secrecy, with conflicting feelings of desire and rejection of the infant and an inability to ask for help. Those around the mothers, often aware of the pregnancy, offered none. In the absence of parallel clinical data, it is not possible to calculate the frequency of the association between neonaticide and denial of pregnancy.

CONCLUSIONS

The term 'denial of pregnancy' cannot fully reflect the complexity of emotions and feelings felt by all perpetrators of neonaticide and is used differently by different professionals. The term itself and its excessive generalization contribute to pathologizing women while absolving those around them and has little operational value in preventing neonaticides. The authors suggest rethinking the terms presently used to describe the phenomenon of pregnancy denial.

Denial of pregnancy: a literature review and discussion of ethical and legal issues

Denial of pregnancy is an important condition that is more common than expected, with an incidence at 20 weeks gestation of approximately 1 in 475. The proportion of cases persisting until delivery is about 1 in 2500, a rate similar to that of eclampsia. Denial of pregnancy poses adverse consequences including psychological distress, unassisted delivery and neonaticide. It is difficult to predict which women will develop denial of pregnancy. There are a number of forms of denial of pregnancy, including psychotic and non-psychotic variants. Denial of pregnancy is a 'red flag' that should trigger referral for psychiatric assessment. A national registry may help to provide more information about this condition and implement appropriate care. This condition poses challenging legal and ethical issues including assessment of maternal capacity, evaluation of maternal (and possibly fetal) best interests and the possibility of detention in hospital.

[Unknown pregnancy--presentation of the case]

INTRODUCTION

There are two kinds of unknown pregnancies. A denied, unknown pregnancy, graviditatas ignota, when the pregnant woman unconsciously denies the existence of the pregnancy. Contrary to the denied pregnancy there is a hidden pregnancy, a concealed pregnancy in women who know they are pregnant but actively hide their pregnancy from the family, partner, friends, teachers, colleagues, etc. The prevalence of an unknown pregnancy during the first 20 gestation weeks is 1 in 475 pregnancies, in the second half of pregnancy it is 1 in 2455 pregnancies and at the moment of delivery it is 1 in 7225.

CASE REPORT

A 40-year-old woman was transported by an ambulance and admitted to Gynecology and Obstetrics Clinic in Kragujevac after the delivery in home conditions and this patient found out about her pregnancy at the moment of delivery.

DISCUSSION

This case presents a classical example of a denied pregnancy. The reasons are probably at all levels, physiological, psychological and social. The patient was 40 years old, with two children aged 17 and 15 and irregular periods. Denied pregnancies present a multidisciplinary problem, which requires work of different specialties and services and this interferes with family and social life.

CONCLUSION

The denied pregnancy should always be taken into consideration in case of irregular periods, especially in perimenopause. Patients in perimenopause should have regular medical examination by their gyneocolgists, at least once in six months and the delivery outside hospital conditions that bears a great risk should be avoided at any rate.

Delusional denial of pregnancy as a special form of Cotard's syndrome: case report and review of the literature

The following case report describes a pregnant woman who was convinced that her pregnancy was non-existent despite being in an advanced stage of clinically obvious pregnancy. The nosologically unspecific syndrome of denial of pregnancy is discussed by reviewing the literature. Based on the existing literature it will be explained why this specific syndrome is considered to indicate a special form of Cotard's syndrome.

The evolutionary biology of cryptic pregnancy: A re-appraisal of the “denied pregnancy” phenomenon

Previous research on 'denied pregnancy', i.e. lack of subjective awareness of pregnancy until the end of gestation in pregnant women, is reviewed and reinterpreted in an evolutionary biological framework. Recent epidemiological studies show that this condition has a much higher incidence than previously thought (about 1:475). Very often, bodily symptoms of pregnancy (nausea, amenorrhea and abdomen swelling) are absent or greatly reduced, and neonates tend to be underweight; in many cases, pregnancy goes undetected also by relatives and physicians. Current explanations in the clinical literature are based on psychodynamic hypotheses about pregnancy-related unconscious conflicts; the lack of symptoms is accounted for by 'somatic denial'. I argue that such psychodynamic accounts are misguided for two reasons: (1) they rest on a failure to recognize the active biological role of the fetus in determining the course of pregnancy, and (2) they ignore the many levels of mother-fetus conflict over resource allocation described by biological theories of parent-offspring conflict. Here I propose to redefine this condition as 'cryptic pregnancy', and begin to explore its possible physiological correlates and evolutionary significance. In the light of parent-offspring conflict theory, cryptic pregnancy appears to reduce the costs of pregnancy, both energetic and ecological (mobility, dependence on kin/mate, etc.), thus favoring the mother at the expense of the fetus. Reduced hCG production and/or effectiveness is likely to be involved in the process. I propose and discuss three nonexclusive evolutionary hypotheses to account for this phenomenon: (1) cryptic pregnancy could be a nonadaptive outcome of conflict resolution processes over resource allocation in pregnancy, possibly related to minor disruptions of genomic imprinting mechanisms. (2) Cryptic pregnancy could result from missed spontaneous abortions of low-quality fetuses. (3) Finally, cryptic pregnancy could be an adaptive pattern of 'forced cooperation' between mother and fetus in stressful or threatening ecological circumstances, as suggested by the reported association with elevated psychosocial stress. In case of reduced survival probability, both mother and fetus would benefit if the mother reduced investment in pregnancy in order to maximize her chances of surviving and reaching delivery.

Denial of pregnancy as a reproductive dysfunction: a proposal for international classification systems

OBJECTIVE

To propose a new Diagnostic and Statistical Manual (DSM) and International Classification of Diseases (ICD) category concerning reproductive dysfunctions not caused by organic disorder.

METHODS

Forensic (n=93) and obstetrical cases (n=78) of denied and concealed pregnancies are compared and discussed.

RESULTS

Denied pregnancies occur with a ratio of 1:475 births. An overwhelming phenomenological agreement is demonstrated between obstetrical and forensic cases. The findings were similar for denial and concealment of pregnancy, probably representing two different types of reproductive dysfunction that can be classified psychosocially together under the heading "negated pregnancy".

CONCLUSIONS

Analogous to the phenomenology of "sexual dysfunctions", "reproductive dysfunctions" could be distinguished by the extraordinariness of both reproductive experience and behavior (as part of human sexuality) and psycho-physiological changes, which characterize the reproductive course of events and cause obvious suffering and interpersonal complications. It is therefore suggested to include these entities as categories in their own right under the appropriate existing headings in DSM and ICD.

Cyclic menstruation-like bleeding during denied pregnancy. Is there a particular hormonal cause?

OBJECTIVE

To investigate whether particular hormonal patterns could explain the persistence of cyclic menstruation-like bleeding during denied pregnancies.

METHODS

Hormone measurements were performed immediately after delivery in a total of 28 subjects with denied pregnancies. The results were studied in three patient subgroups: subjects with any cyclic bleeding during pregnancy (n = 22), subjects with cyclic bleeding during pregnancy until the delivery date (n = 7) and subjects with amenorrhea (n = 6). These data were compared with those of a control group (n = 126). In some of the women who reported cyclic bleeding, hormone assessments were also done once the lactation period ended.

RESULTS

For estradiol, free estriol and progesterone, no more than two values in each group were outside the 95% confidence interval of the control group. Several results for prolactin were remarkably lower. The findings for human chorionic gonadotropin, free testosterone, dehydroepiandrosterone sulfate, alpha-fetoprotein and thyroid-stimulating hormone were almost all within the 95% confidence interval. In seven subjects, abnormal results were obtained for the gondaotropin-releasing hormone/thyrotropin-releasing hormone test and the metoclopramid test after delivery and lactation. All of these subjects showed signs of corpus luteum insufficiency. In five subjects, evidence of hyperprolactinemia was found.

CONCLUSION

Results revealed that hormonal patterns assessed immediately after delivery do not provide any causal explanation for the cyclic menstruation-like bleeding that occurs during denied pregnancies. Hormone assessments performed after the lactation period, i.e. during a normal menstrual cycle, showed a number of abnormalities. However, a causal relationship could not be drawn.

Preventing the Tragedy of Neonaticide

Denying a pregnancy can result in consequences as tragic as neonaticide--the killing of an infant in the first 24 hours of life. Between 150 and 300 neonaticides are committed each year but the actual prevalence of pregnancy denial is unknown. Adolescents are especially vulnerable to pregnancy denial because the unexpected event creates such enormous anxiety and fear for them. Pregnancy denial often eludes parents, teachers, and health care providers. Nurses can advocate for resources and pregnancy screening in primary care settings, and help educate parents and teachers about the problem.

Elevated risk for neonatal outcome following denial of pregnancy: results of a one-year prospective study compared with control groups

AIMS

Newborns following denied pregnancies are delivered after either late onset or total absence of antenatal care, with a presumed subsequently increased risk for neonatal outcome. For this specific group, several characteristic outcome parameters are investigated.

METHODS

During the period July 1, 1995 to June 30, 1996, a prospective case sampling was performed for denied pregnancies in Berlin. Besides determination of the parameters' frequency, comparison with two control groups is performed: a normal group (BBR, all Berlin deliveries in 1995) and a high risk group (VIR, all deliveries at a perinatal center in 1996).

RESULTS

Altogether 69 neonates occurred. For gestational age < 37 weeks, birth weight < 2500 g, small for gestational age, transferal rate of newborns to neonatal unit and surgical delivery, a statistically significant worse outcome is demonstrated for denied pregnancies versus BBR and VIR (p-level < 0.05). Neonatal mortality is 5.8% in all cases, the corrected rate is 1.5% (excluding three non-viable cases of 21st and 23rd week of gestation).

CONCLUSIONS

The data underline the elevated fetal outcome risk for newborns after denial of pregnancy. In this group, total absence or late onset of antenatal care results in a manifestation of pregnancy dependent risks. Preterm births and small for gestational age newborns, together with deaths, may be classified as at least potentially avoidable.
