Fetal Thyrotoxicosis due to Maternal TSH Receptor Stimulating Antibodies Causes Infant Central Hypothyroidism.

Introduction: Women with a current diagnosis or past history of Graves' disease (GD) are at risk of developing fetal thyrotoxicosis (FT) during pregnancy when they are inadequately treated, or because of placental passage of TSH receptor antibodies (TRAb). It is known that FT induced by high maternal thyroid hormone concentrations may result in infant (central) hypothyroidism.

Case Presentation: In a euthyroid woman with a history of GD treated with radioactive iodide (I131), persistently high levels of maternal TRAb resulted in recurrent FT during two separate pregnancies, followed by neonatal hyperthyroidism and infant central hypothyroidism.

Surgical management of pituitary adenoma during pregnancy.

Background: Although conservative treatment is typically recommended for pregnant patients with pituitary adenoma (PA), surgical treatment is occasionally necessary for those with acute symptoms. Currently, surgical interventions utilized among these patients is poorly studied.

Aim: To evaluate the surgical indications, timing, perioperative precautions and postoperative complications of PAs during pregnancy and to provide comprehensive guidance.

Metabolic effects of early life stress and pre-pregnancy obesity are long lasting and sex specific in mice.

Early life stress (ELS) is associated with metabolic, cognitive, and psychiatric diseases and has a very high prevalence, highlighting the urgent need for a better understanding of the versatile physiological changes and identification of predictive biomarkers. In addition to programming the hypothalamic-pituitary-adrenal (HPA) axis, ELS may also affect the gut microbiota and metabolome, opening up a promising research direction for identifying early biomarkers of ELS-induced (mal)adaptation. Other factors affecting these parameters include maternal metabolic status and diet, with maternal obesity shown to predispose offspring to later metabolic disease.

[Application of acupuncture in treatment of diseases with ovarian function decline].

Taking regulating the thoroughfare vessel and the conception vessel, tonifying liver and kidney, calming mind as the treatment principle, acupuncture (acupuncture for regulating menstruation and promoting pregnancy) is commonly used in clinical treatment of diseases with ovarian function decline, and recommends full cycle acupuncture treatment. Clinical research shows that acupuncture can improve menstruation and ovulation, increase the reserve function and response of ovary as well as endometrial receptivity, so as to improve the pregnancy outcome. It can also improve the related symptoms caused by negative emotions and low estrogen, and comprehensively enhance the health related quality of life in patients.

Clinical management and obstetric outcome in WFS1 Wolfram syndrome spectrum disorder: A case report and literature review.

Objective: Wolfram Syndrome (WS) is a rare autosomal recessive neurodegenerative disorder caused by mutations in WFS1 or CISD2 (WFS2). We present a rare case report of pregnancy with WFS1 spectrum disorder (WFS1-SD) in our hospital and reviewed literature to provide the management of pregnancy in these patients through multi-disciplinary cooperation.

Case Report: A 31-year-old (gravida 6, para 1) woman with WFS1-SD conceived naturally.

Novel Candidate Regulators and Developmental Trajectory of Pituitary Thyrotropes.

The pituitary gland regulates growth, metabolism, reproduction, the stress response, uterine contractions, lactation, and water retention. It secretes hormones in response to hypothalamic input, end organ feedback, and diurnal cues. The mechanisms by which pituitary stem cells are recruited to proliferate, maintain quiescence, or differentiate into specific cell types, especially thyrotropes, are not well understood.

Comparison of fixed and flexible progestin-primed ovarian stimulation protocols to prevent premature luteinization in patients with diminished ovarian reserve.

Purpose: Flexible progestin-primed ovarian stimulation (PPOS) protocol is demonstrated to be effective in suppressing premature luteinization in few studies. We aimed to compare fixed and flexible PPOS protocols in preventing premature luteinization in patients with diminished ovarian reserve.

Methods: This retrospective cohort study included patients with a diminished ovarian reserve who were administered PPOS protocols for pituitary suppression during ovarian stimulation in a tertiary center in between January 2019 and June 2022.

Italian Guidelines for the Management of Prolactinomas.

Introduction: This guideline (GL) is aimed at providing a reference for the management of prolactin (PRL)-secreting pituitary adenoma in adults. However, pregnancy is not considered.

Methods: This GL has been developed following the methods described in the Manual of the Italian National Guideline System.

Safety of pregnancy in acromegaly patients and maternal and infant outcomes after pregnancy: single-center experience from China and review of the literature.

Background: Pregnancy in acromegaly is uncommon and still in debate for fear of tumor progression or potential threat to both mother and fetus's health. Besides, the data for pregnancy complications in uncontrolled acromegaly is limited. Thus, the objective of this study was to summarize pregnancy safety and disease courses after pregnancy in acromegalic patients and review their clinical characteristics based on disease activity in the literature.

Maternal history of childhood maltreatment is associated with diurnal cortisol and DNA methylation of placental 11-beta-hydroxysteroid dehydrogenase type 2.

Background: Accumulating evidence indicates that maternal hypothalamic-pituitary-adrenal (HPA) axis activity over pregnancy differs according to maternal history of childhood maltreatment. DNA methylation of the placental 11-beta-hydroxysteroid dehydrogenase (BHSD) type 2 enzyme regulates fetal exposure to maternal cortisol, yet the association between maternal history of childhood maltreatment and methylation of placental 11BHSD type 2 has not been previously studied.

Methods: We examined if maternal cortisol production at 11 and 32 weeks' gestation (n = 89) and placental methylation of the 11BHSD type 2 gene (n = 19) differed among pregnant women with and without histories of childhood maltreatment.

Placenta DNA methylation levels of the promoter region of the leptin receptor gene are associated with infant cortisol.

The intrauterine environment and early life stress regulation are widely recognized as an early foundation for lifelong physical and mental health. Methylation of CpG sites in the placenta represents an epigenetic modification that can potentially affect placental function, influence fetal development, and ultimately impact the health of offspring by programming the hypothalamic-pituitary-adrenal (HPA) axis stress response during prenatal development. Leptin, an adipokine produced by the placenta, is essential for energy homeostasis.

Diagnosis and Management of Pituitary Adenomas: A Review.

Importance: Pituitary adenomas are neoplasms of the pituitary adenohypophyseal cell lineage and include functioning tumors, characterized by the secretion of pituitary hormones, and nonfunctioning tumors. Clinically evident pituitary adenomas occur in approximately 1 in 1100 persons.

Observations: Pituitary adenomas are classified as either macroadenomas (≥10 mm) (48% of tumors) or microadenomas (<10 mm).

Transgenerational effects of maternal exposure to nicotine on structures of pituitary-gonadal axis of rats.

Smoking can lead to several diseases and cause a reduction in fertility in men and women. Among the various components of cigarettes harmful during pregnancy, nicotine stands out. It can cause a reduction in placental blood flow, compromising the development of the baby with neurological, reproductive and endocrine consequences.

[Transient thickening of the pituitary stalk followed by a supra-pituitary Langerhansian histiocytosis : consequence or mere coincidence ?].

One of the difficult challenges in endocrinology is the etiological diagnosis of isolated thickened pituitary stalk (PS). We report the case of a woman in whom a thickened PS was diagnosed following the onset of central diabetes insipidus revealed by polyuria-polydypsia syndrome of late pregnancy and postpartum. The pituitary exploration showed panhypopituitarism with disconnecting hyperprolactinemia.

Effectiveness of letrozole in pituitary downregulated normogonadotrophic young women with an initial poor response.

It has been reported that 10 to 15% of young normogonadotrophic women show suboptimal response to standard long protocols. Letrozole (LE), an aromatase inhibitor, was shown to improve ovarian sensitivity to follicle stimulating hormone (FSH) and follicular response to gonadotrophin treatment in poor ovarian response patients. We reasoned that it might be possible to utilize LE in young normogonadotrophic patients with unexpected hypo-response in standard gonadotropin-releasing hormone agonist long protocol.

[Cushing's disease in pregnancy and treatment with cabergoline: obstetric and neonatal results].

Introduction:: Cushing's disease (CD) is rare during pregnancy and is associated with significant maternal and fetal complications. The aim was to report the case of a patient with CD who achieved pregnancy and delivery without complications after treatment with low doses of cabergoline.

Methods:: A 29-year-old woman diagnosed with CD (ACTH-secreting macro-tumor that produces displacement of the optic chiasm, infiltrates the right cavernous sinus and includes the internal carotid artery).

Approach to the Patient With Prolactinoma.

Prolactinomas are the most common pituitary tumor histotype, with microprolactinomas being prevalent in women and macroprolactinomas in men. Hyperprolactinemia is among the most common causes of hypogonadotropic hypogonadism in both sexes, prompting medical advice for hypogonadism (infertility, oligo-amenorrhea, impotence, osteoporosis/osteopenia) in both sexes, and for signs and symptoms of mass effects (hypopituitarism, visual loss, optic chiasm compression, cranial nerve deficits, headaches) predominantly in men. Diagnostic workup involves a single prolactin measurement and pituitary imaging, but some laboratory artifacts (ie, the "hook effect" and macroprolactin) can complicate or delay the diagnosis.

Lymphocytic Hypophysitis: An Underrated Disease.

Lymphocytic hypophysitis (LYH) is a rare inflammatory disease in which lymphoplasmacytic infiltration of the pituitary gland can potentially lead to panhypopituitarism. This entity was first recognized in 1962 by Goudie and Pinkerton. We report the case of a 36-year-old nonpregnant female operated for a presumed nonsecreting pituitary adenoma.

[Pituitary insufficiency: basics in diagnosis and therapy].

Pituitary insufficiency is a partial or complete failure of secretion of one or more hormones from the pituitary gland. The pituitary gland is located in the hypophysial fossa of the sella turcica of the os sphenoidale and produces ACTH, LH, FSH, GH, TSH, and prolactin. Pituitary insufficiency can be caused by acute damage, such as secondary to traumatic brain injury.

[Management of prolactinoma prior to, during, and after pregnancy].

Hyperprolactinemia should actively be investigated as a potential reason of infertility. Underlying prolactinomas may successfully be treated with dopamine agonists. However, patients with micro- or well-circumscribed macroprolactinomas (Knosp 0 or 1) should also be informed about transsphenoidal surgery offering cure in contrast to long-lasting medical therapy.

Effectiveness of mindfulness training on pregnancy stress and the hypothalamic-pituitary-adrenal axis in women in China: A multicenter randomized controlled trial.

Introduction: In the past two decades, mindfulness-based intervention programs have gradually become popular.Many studies have confirmed that these programs can effectively alleviate prenatal stress and negative emotion.The mindfulness-based stress-buffering hypothesis suggests that mindfulness training can induce changes in the levels of the cortisol secreted by the HPA axis, thereby reducing stress susceptibility.

Antipsychotic-Related Prolactin Levels and Sexual Dysfunction in Mentally Ill Youth: A 3-Month Cohort Study.

Objective: Although these agents are used frequently, prospective data comparing serotonin/dopamine antagonists/partial agonists (SDAs) in youth regarding prolactin levels and sexual adverse effects (SeAEs) are scarce.

Method: Youth aged 4 to 17 years, SDA-naive (≤1 week exposure) or SDA-free for ≥4 weeks were followed for ≤12 weeks on clinician's-choice aripiprazole, olanzapine, quetiapine, or risperidone. Serum prolactin levels, SDA plasma levels, and rating scale-based SeAEs were assessed monthly.

Partial Sheehan's syndrome with abdominal tuberculosis presented with pancytopenia and fluctuating thyroid profile: a case report.

Unlabelled: Sheehan's syndrome is a well-recognized cause of panhypopituitarism secondary to pituitary apoplexy, followed by postpartum hemorrhage. Depending upon the degree of ischemic injury, it can be either partial or complete.

Case Presentation: We report an interesting case of a 35-year-old woman admitted to our hospital with complaints of abdominal distension, which was later presumed to be due to disseminated tuberculosis (TB) after excluding the possible differentials.
