Modulatory effect of vitamin B6 on sex hormone receptors, thyroid, and kisspeptin/kiss1r system in the uterus of pseudopregnant bitches.

This study evaluated whether the treatment of pseudopregnancy in bitches with vitamin B6 modulates uterine expression of receptors for progesterone (PR), oestrogen (ERα), androgen (AR), thyroid hormone (TRα) and the kisspeptin/Kiss1r system. Eighteen pseudopregnant bitches were treated for 20 days in groups receiving placebo (n = 6); cabergoline (5 µg/kg/day; n = 6); or vitamin B6 (50 mg/kg/day; n = 6). Blood was collected on the 1st day of drug administration and 120 h later to measure serum prolactin (PRL). After treatment, they were ovariohysterectomized and uterine fragments were collected for histomorphometry and immunohistochemical evaluation of PR, ERα, AR, TRα, Kiss1 and Kiss1r. After 120 h of cabergoline or vitamin B6 treatment, PRL levels were reduced in the bitches, confirming the antiprolactinemic effect of these drugs. Furthermore, regardless of treatment, the animals exhibited uterine histomorphometry consistent with dioestrus. The PR showed strong immunostaining in all regions and an increase in scores was observed for this receptor in animals treated with vitamin B6 in deep glands. In contrast, ERα and Kiss1R receptors showed weak to no immunostaining in all uterine regions and no changes between groups. Regarding AR, most animals treated with vitamin B6 showed increased trends in the deep gland and myometrium marking scores. In contrast, in both vitamin B6 and cabergoline treatments, a reduction in TRα marking scores was observed compared to the control group. In addition, on the endometrial surface, a reduction was observed in the marked area of Kiss1 after administration of cabergoline when compared to the pseudopregnant control group. These findings shed valuable insight into the use of vitamin B6 as a drug with actions similar to cabergoline in reducing PRL and uterine modulation in bitches.

The role of sociocultural factors in rare medical conditions: The first case report of pseudocyesis in an Ethiopian woman with major depressive disorder.

Our case report highlights pseudocyesis, a rare medical condition in a 40-year-old woman with comorbid major depressive disorder. Cultural influences on experiences, and the need for understanding sociocultural factors in mental health, are emphasized in low-resource settings.

Pseudociesis. Reporte de caso / Psedocyesis. Case report

Introducción: Según el DSM-V, la pseudociesis se incluye en la categoría "otros síntomas somáticos específicos y trastornos relacionados" y se define como la falsa creencia de estar embarazada que se asocia con signos objetivos y síntomas de embarazo. La confirmación de la pseudociesis se consigue con un resultado negativo de la gonadotropina coriónica humana beta en la sangre y/o la orina asociado a un hallazgo ecográfico negativo. Materiales y métodos: se presenta el caso de mujer con síntomas y signos de embarazo que corresponden a pseudociesis, la paciente siguió creyendo que estaba embarazada debido a sus síntomas, a pesar de que las pruebas de embarazo dieron negativo. Conclusión: La pseudociesis es una enfermedad poco frecuente que a menudo se asocia a otras comorbilidades psiquiátricas y diagnósticos diferenciales poco claros. Es necesario la realización de más estudios, incluyendo series de casos y revisiones sistemáticas para comprender mejor esta infrecuente condición y sus otras variantes.

Introduction: According to the DSM-V, pseudocyesis is included in the category "other specific somatic symptoms and related disorders" and is defined as a false belief of being pregnant that is associated with objective signs and symptoms of pregnancy. Confirmation of pseudocyesis is achieved with a negative blood and/or urine beta-human chorionic gonadotropin result and a negative ultrasound finding. Materials and methods: We present a case of a woman with symptoms and signs of pregnancy corresponding to pseudocyesis, the patient continued to believe she was pregnant because of her symptoms, despite negative pregnancy tests. Conclusion: Pseudocyesis is a rare condition that is often associated with other psychiatric comorbidities and unclear differential diagnoses. Further studies, including case series and systematic reviews, are needed to better understand this rare condition and its other variants.

A rare case report of pseudo-pregnancy in a menopausal female.

Pseudo-pregnancy is an uncommon psychiatric presentation, often having a complex interplay of psycho-social factors making it difficult to manage. It is common to present in the reproductive age range, rarely in postmenopausal women. We are reporting a rare presentation of a 48-year post-menopausal widowed HIV-positive female with no live issues having two years of secondary amenorrhea complaining to have documented weight gain and experience of perceiving fetal movements for the past 5 months. However, she persistently insisted on antenatal care despite repeated reports of ultra-sonographic pelvis imaging and gynecological examination pointed toward menopausal changes and the absence of any live issue. This case report emphasizes the clinical presentation and management strategies for patients with pseudocyesis, a peculiar and rare psychiatric manifestation.

Primary Ovarian Mucinous Adenocarcinoma, Expansile Type, Misperceived As Pregnancy by the Patient.

We present the case of a woman in her 20s with an eight-month history of increasing abdominal distention, dyspnea, and night sweats. The patient believed she was pregnant despite being told at another hospital that the pregnancy tests were negative, and no fetus was seen on an abdominal ultrasound. The patient delayed obtaining follow-up because of a distrust of the healthcare system and presented to our hospital at the behest of her mother. On physical examination, the abdomen was distended with a positive fluid wave, and a large mass was palpated in the abdomen. Gynecological examination was limited because of severe abdominal distension but a mass was palpable in the right adnexa. A pregnancy test and fetal ultrasound were performed, and the patient was not pregnant. A CT scan of the abdomen and pelvis revealed a large mass arising from the right adnexa. She underwent right salpingo-oophorectomy, appendectomy, omentectomy, lymph node dissection, and peritoneal implant resection. The biopsy confirmed intestinal-type IIB primary ovarian mucinous adenocarcinoma, expansile type, with peritoneal spread. Chemotherapy was provided for three cycles. A follow-up CT scan of the abdomen showed no evidence of a tumor six months after surgery.

Delusion of Pregnancy: A Case Report and Literature Review.

Delusion of pregnancy is defined as a persistent belief that one is pregnant despite concrete evidence to the contrary. Despite being reported as an isolated event, delusion of pregnancy has been reported in many patients with underlying psychiatric conditions such as schizophrenia, bipolar disorder, psychotic depression, and other physiological disorders of mental function. This case study reports a case of a 44-year-old, drug-naïve female with delusion of pregnancy affected by paranoid schizophrenia. Pharmacological treatments are frequently insufficient in controlling this condition and are often supplemented with adjunctive psychotherapy.

[Mother brain: Bayesian theory of maternal interoception during pregnancy and postpartum]. / Cerveau maternel : Théorie bayésienne de l'intéroception maternelle pendant la grossesse et le postpartum.

The perinatal period, including pregnancy and postpartum, causes major morphological, endocrinal, and thermal transitions in women. As the fetus grows, abdominal muscle fibers stretch, internal organs such as the bladder or colon move, and the uterine anatomy changes. Many of these changes involve interoception, the perception of internal body signals such as muscle and visceral sensations. Despite the importance of these interoceptive signals, few studies have explored perinatal interoception. We propose an innovative theory of maternal interoception based on recent findings in neuroscience. We show that interoceptive signals processing during pregnancy is crucial for understanding perinatal phenomenology and psychopathology, such as maternal perception of fetal movements, maternal-infant bonding, denial of pregnancy, phantom fetal movements after childbirth, pseudocyesis or even puerperal delusion. Knowing the importance of these interoceptive mechanisms, clinicians in obstetrics, gynecology and mental health should be particularly vigilant to maternal interoception during the perinatal period.

Delusion of pregnancy: Conception in brain.

Delusional disorders are common psychiatric disorders, but a delusion of pregnancy is a rare condition. Four cases that presented at a single tertiary care psychiatry center with delusion of pregnancy as a part of different psychological disorders are illustrated here. These cases were seen over a period of 6 months and had varied presentations and associated psychopathologies. Three of the four patients showed rapid recovery to treatment, but one patient was lost to follow-up. The heterogeneity in the presentation, sociodemographic profile of the patients and even in the symptom profile and response to treatment in this condition is highlighted and discussed in this case series.

Medical considerations in delusion of pregnancy: a systematic review.

PURPOSE: Delusions of pregnancy are associated with functional impairment and psychological distress. Previous works have focused on characterizing their etiology and identifying contributory social and cultural factors. The purpose of this review is to give an overview of the literature on medical or surgical comorbidities associated with delusions of pregnancy. METHODS: We searched Google Scholar, PubMed, and PsycInfo using the terms "pregnancy delusion," "delusional pregnancy," "pseudocyesis", and "false/pseudo/phantom/spurious pregnancy" to identify all published cases of delusional pregnancies. We included cases in which medical or surgical factors might have contributed to the delusion. We extracted the following information from selected case reports: patient age, psychiatric diagnoses, medications, medical comorbidities, somatic complaints, treatment, and outcome. RESULTS: We found that 23 of 140 cases (16.4%) were potentially influenced by concomitant medical or surgical conditions including gallstones, abdominal tumors, hyperprolactinemia, constipation, a tubal cyst, and esophageal achalasia. Medical or surgical treatment was pursued in 15 of these 23 cases, followed by mitigation of the delusion in ten cases. CONCLUSIONS: We emphasize the importance of a thorough workup including physical and gynecological examinations in patients presenting with a delusion of pregnancy. Clinicians should recognize and overcome potential barriers to undertaking comprehensive assessments in order to prevent delays in management and treatment of underlying medical or surgical conditions.

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.

A Rare Case of Pseudocyesis in a Patient With Bipolar Disorder.

Pseudocyesis is a rare condition in which a person has a false belief of being pregnant, accompanied by objective signs and symptoms of pregnancy, despite not being pregnant. Confirmation of pseudocyesis is achieved with a negative result of beta-human chorionic gonadotropin in the blood and/or urine and negative ultrasound finding. Most cases of pseudocyesis occur in the setting of major depressive disorder or psychotic disorder, with very few occurring during a manic episode of bipolar disorder. Hence, we present a 30-year-old woman with pseudocyesis in the setting of bipolar disorder, specifically within a current manic episode with features of psychosis. The patient was found in the woods naked, with signs of psychosis. She described symptoms of increasing abdominal size, whitish discharge from her nipple, and feeling of fetal movement. The patient continued to believe she was pregnant due to her symptoms, despite negative pregnancy tests on multiple occasions. She has a history of bipolar disorder and post-traumatic stress disorder. Her examination showed an obese woman, with a non-distended abdomen and non-palpable uterus with no breast tenderness or enlargement. The patient was given olanzapine for her agitation and was subsequently stabilized with haloperidol and lorazepam. She was restarted on her home medications, including risperidone, oxcarbazepine, and topiramate. She was later committed involuntarily and transferred to a long-term psychiatry facility. Pseudocyesis is a rare condition often associated with other psychiatric comorbidities. Our patient's presentation highlights one of the few cases ever formally documented in a developed country, as most of the cases reported are found in developing countries. More studies, including case series and systematic reviews, need to be done to better understand this rare condition and its other variants.

Prolactin and human weight disturbances: A puzzling and neglected association.

Weight gain at the outset of prolactinomas in many women is well documented. Yet, this symptom is absent from the clinical descriptions of the disease in textbooks and reviews. This omission is almost certainly due to the absence of a physiological explanation for the phenomenon, as prolactin is not a recognized fat promoting hormone. In this review we present the clinical evidence for a relationship between prolactin and fat accumulation and address some possible mechanisms involved. We put forward the hypothesis that prolactin is a component of a neuroendocrine program - maternal subroutine - aimed at optimizing the care of the young through the production of milk, promotion of maternal behavior and increase in the metabolic efficiency of the mother. These adaptations can enable her to face the extraordinary metabolic expenses of pregnancy and nursing, especially during times of suboptimal environmental conditions. We emphasize the uniqueness of prolactin in that it is a hormone that is tonically inhibited and which has its major effects on the regulation of an inter-individual (the mother - offspring dyad), rather than an intra-individual, system. This approach opens a window to consider the possibility of external events as regulators of this system. It also allows addressing a variety of hitherto unexplained findings reported in the literature. Examples include: association of prolactinomas with paternal deprivation and with stressful life events; pseudocyesis; acute life event-driven episodes of galactorrhea; episodes of rapid weight gain following a life event; prolactin surges (without associated cortisol surges) following some psychological stresses.

Canine pseudopregnancy: an evaluation of prevalence and current treatment protocols in the UK.

BACKGROUND: There is a dearth of literature on pseudopregnancy in the bitch, with only a few treatment-based studies published since the 1990s. Pseudopregnancy may be under-recognised in bitches and may account for a proportion of behavioural cases seen in veterinary practices including aggression. Little is known about commonly used treatments for overtly pseudopregnant bitches and it is possible that current regimes may not be prescribed for a sufficient duration to control any clinical signs including, physical and behavioural changes. To investigate current trends in diagnosis and treatment of canine pseudopregnancy, a postal survey was sent to 2000 randomly selected veterinary surgeons in UK veterinary practices. The questionnaire queried how often vets recognise cases of pseudopregnancy in spayed and entire bitches, which physical or behavioural signs are commonly recognised for diagnosis, and which management or treatment protocols are used. RESULTS: The response rate was 19.8% (397/2000). Ninety-six percent of veterinary surgeons reported seeing pseudopregnant bitches showing behavioural changes without any physical changes within the last 12 months. Of those behavioural changes, collecting and mothering objects was the most frequently reported behavioural sign (96%). Ninety-seven percent of vets had seen aggression in pseudopregnant bitches. Nevertheless, only 52% of vets routinely asked owners about behavioural changes during consultations. Forty-nine percent of respondents reported seeing pseudopregnancy in spayed bitches. The most commonly reported physical sign was enlarged mammary glands and/or milk production (89%). Treatment options varied (surgical, medical or none) and depended on duration and severity of physical and behavioural signs, owners' preference, cost, concurrent disease, drug availability and previous history. CONCLUSIONS: This is the largest epidemiological study of canine pseudopregnancy in the UK. The prevalence and severity of clinical signs in dogs with pseudopregnancy are variable and possibly under-estimated. Dogs with overt pseudopregnancy experience diverse physical and behavioural changes and information on standard treatment protocols are lacking. Although, progress on our understanding of diagnosis and treatment of pseudopregnancy in spayed and entire bitches has been made, further studies are warranted.

A Case of Concomitant Pseudocyesis and Couvade Syndrome Variant.

Per DSM-V, pseudocyesis is included under the category "other specified somatic symptom and related disorder" and is defined as a false belief of being pregnant that is associated with objective signs and reported symptoms of pregnancy. The male counterpart of pseudocyesis is Couvade syndrome, also called "sympathetic pregnancy" where a man experiences symptoms of pregnancy when his female partner is pregnant. There are extensive reports on pseudocyesis and Couvade syndrome in psychiatric literature but none with features of both, in a single case. Here we present a unique case of a fifty-eight-year-old mother who presented with symptoms of concomitant pseudocyesis and Couvade syndrome concurrently when her daughter was pregnant. This case report discusses the epidemiology, course of symptoms and common comorbidities associated with this interesting diagnosis.

Biopsychosocial view to pseudocyesis: A narrative review.

BACKGROUND: Pseudocyesis is a psychopathological clinical syndrome in which a non-pregnant woman firmly believes herself to be pregnant and manifests many symptoms and signs of pregnancy. Although the exact etiology of pseudocyesis has not been determined. OBJECTIVE: This study was conducted with the aim of assessing the biopsychosocial view to pseudocyesis. MATERIALS AND METHODS: A comprehensive search in electronic databases such as Google Scholar, PubMed, ScienceDirect, Web of Science, and Scopus was conducted between 1943-2016 to retrieve pseudocyesis related articles. For this purpose, 1149 articles were collected and 66 items were used. RESULTS: Findings were classified into 2 main categories: a) pseudocyesis etiology, which could include (biological psychological factors and psychiatric disorders, and social factors); and b) pseudocyesis management. CONCLUSION: Pseudocyesis results from a multidimensional group of factors, and a holistic and comprehensive approach should be taken to its treatment. Cooperation between gynecologists and psychiatrists would likely be useful in addressing the condition.

Pseudocyesis Vera in a Health Institution, North Western Nigeria.

Pseudocyesis was first reported in 19th Century and several others have been subsequently reported. The classes of the illness include Pseudocyesis vera, Delusional Pseudocyesis, Stimulated Pseudocyesis and Erroneous Pseudocyesis. This case report typifies Pseudocyesis vera called true pseudocyesis. It is said to be commoner in rural communities, where people don't have access to maternity services and where found they were not being used. It is authors' believe that such illness can be prevented with more enlightenment on advantages of use of available antenatal services.

Pseudocyesis, delusional pregnancy, and psychosis: The birth of a delusion.

Both pseudocyesis and delusional pregnancy are said to be rare syndromes, but are reported frequently in developing countries. A distinction has been made between the two syndromes, but the line of demarcation is blurred. The aim of this paper is to review recent cases of pseudocyesis/delusional pregnancy in order to learn more about biopsychosocial antecedents. The recent world literature (2000-2014) on this subject (women only) was reviewed, making no distinction between pseudocyesis and delusional pregnancy. Eighty case histories were found, most of them originating in developing countries. Fifty patients had been given a diagnosis of psychosis, although criteria for making the diagnosis were not always clear. The psychological antecedents included ambivalence about pregnancy, relationship issues, and loss. Very frequently, pseudocyesis/delusional pregnancy occurred when a married couple was infertile and living in a pronatalist society. The infertility was attributed to the woman, which resulted in her experiencing substantial distress and discrimination. When antipsychotic medication was used to treat psychotic symptoms in these women, it led to high prolactin levels and apparent manifestations of pregnancy, such as amenorrhea and galactorrhea, thus reinforcing a false conviction of pregnancy. Developing the erroneous belief that one is pregnant is an understandable process, making the delusion of pregnancy a useful template against which to study the evolution of other, less explicable delusions.

Pseudocyesis: A complication of antipsychotic-induced increased prolactin levels and weight gain.

Pseudocyesis or phantom pregnancy is characterized by a false belief in a non-pregnant female that she is pregnant and this belief is usually associated with bodily signs of pregnancy. In some of the patients, this belief is held with delusional conviction. In this case report, we present the case of a female patient who presented with delusional belief of being pregnant, which was associated with antipsychotic-associated increase in prolactin levels and metabolic syndrome.

Pseudocyesis Versus Delusion of Pregnancy: Differential Diagnoses to be Kept in Mind.

Pseudocyesis is a condition in which the patient has all signs and symptoms of pregnancy except for the confirmation of the presence of a fetus. The literature on delusions of pregnancy in schizophrenia is however scanty. We hereby present a case of delusion of pregnancy. The case highlights the possibility of delusion of pregnancy if a patient presents with features suggestive of pseudocyesis. The obstetricians being more familiar with pseudocyesis might tend to overlook the other possibility in such cases. This would be especially true if there are no associated clearcut psychotic features.
