Tumor metastasis to the pituitary gland is a rare, not well-documented and life-threatening condition associated with a shortened life span. A better understanding of its clinical manifestations could lead to earlier diagnosis, appropriate therapy and potentially improving quality of life. Therefore, we retrospectively studied the charts of patients with pituitary metastases who were treated at the City of Hope National Medical Center (Duarte, CA) from 1984 to 2018. We reviewed and analyzed tumor origin, primary pituitary clinical manifestation, duration between primary tumor diagnosis and pituitary metastasis, type of treatment and patient survival. A total of 11 patients were identified with a mean age of 59.2 years and median survival following the diagnosis of metastasis of 10 months. Breast cancer and lymphoma were the most common primary origins in these cases, and diabetes insipidus and panhypopituitarism were the most common clinical manifestations of their metastasis. We also compared our results with reports in the literature published between 1957 and 2018. A total 289 patients with pituitary metastasis have been reported in the literature. Breast cancer was the most frequent primary origin of the metastasis, and visual symptoms were the most common primary manifestation. The posterior part of the pituitary is more susceptible than the anterior to metastasis. Pituitary metastasis may occur as a consequence of successful primary tumor treatment prolonging the chance of seeding. Future studies are needed to determine the molecular mechanism of metastasis to the pituitary.

Prenatal stress can lead to the programming of the neuroendocrine system in male offspring, disrupting the hypothalamic testicular axis and adversely affecting the reproductive health of male offspring. This study aimed to determine the long-term effects of prenatal stress on the KISS1 system in male offspring and the effects on reproductive function in male offspring. Sixteen pregnant females were divided into a prenatal control group (PC,n=8) and a prenatal stress group (PS,n=8). The PS group was modeled with chronic unpredictable mild stress (CUMS) from day 1 of gestation to full-term delivery. Differences between the two groups in various maternal parameters, including glucocorticoid secretion, litter size, and the effects of male offspring birth weight, the KISS1 system, and reproductive function, were determined. Male offspring of PS dams had lower birth weights compared to prenatal controls.KISS1 gene expression is reduced at birth and in adult PS offspring, and its receptor KISS1-R protein is similarly reduced in PS offspring at birth and adulthood. In adulthood, PS male offspring show significantly reduced sex hormone production, altered testicular morphology, reduced maturation of their supporting cells, and decreased expression of connexin 43 (CX43), leading to an altered sperm microenvironment and reduced sperm quality. In conclusion, prenatal stress leads to adverse changes in the KISS1 system in male offspring and decreased reproductive function.

The presence of an additional X or Y chromosome (sex chromosome trisomies, SCT) is associated with an increased risk for neurodevelopmental difficulties, including socio-emotional problems, across the life span. Studying emotion regulation in young children with SCT could signal deviations in emotional development that serve as risk markers to guide clinical care. This study explored the presence and variety of emotion regulation strategies in 75 SCT children and 81 population-based controls, aged 1–7 years, during a frustration-inducing event in which physiological (heart rate) and observational data (behavioral responses) were collected. Children with SCT were equally physiologically aroused by the event as compared to controls. However, they showed more emotion regulation difficulties in terms of behavior compared to controls that were not explicable in terms of differences in general intellectual functioning. Specifically, they had a more limited range of behavioral alternatives and tended to rely longer on inefficient strategies with increasing age. The field of practice should be made aware of these early risk findings regarding emotion regulation in SCT, which may potentially lay the foundation for later socio-emotional problems, given the significant impact of emotion regulation on child and adult mental health outcomes. The current results may help to design tailored interventions to reduce the impact of the additional sex chromosome on adaptive functioning, psychopathology, and quality of life.
