Unlabelled: The deficiency of two or more pituitary hormones is called multiple pituitary hormone deficiencies (MPHD). Its prevalence is estimated to be about 1/8,000 worldwide.
Objective: To present the diagnosis processes, clinical findings, and long-term follow-up of patients with MPHD.
Patients And Method: Between 1999 and 2015, patients diagnosed with MPHD were evaluated. Clinical presentation, anthropometry, imaging studies, and clinical evolution were analyzed. Hormone status was evaluated, including growth hormone (GH), thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), follicle-stimulating hormone/luteinizing hormone (FSH/LH), and prolactin (PRL). Data were assessed using the student's t-test and the Mann-Whitney U test. Spearman's correlation was used for correlations. A p-value < 0.05 was considered statistically significant.
Results: Forty-five patients were included; 55.6% were male, the mean age at presentation was 5.6 ± 3.9 (0-14.4) years, and the median bone age was 3.5 ± 2.3 (0.5-11) years. At admission, GH deficiency was found in 88.9% of the cases, TSH deficiency in 77.8%, ACTH deficiency in 33.3%, FSH/LH deficiency in 22.2%, and PRL deficiency in 17.8%. During the follow-up, 62% of the cases added other hormone deficiencies. The mean follow-up period was 9.18 ± 3.6 (3.02-17.2) years.
Conclusion: Patients with MPHD have very different clinical presentations, with GH and TSH deficiency being the most common in this study. Additional hormonal deficiencies can occur even years after the initial diagnosis and our results demonstrate that genetic height potential is achieved with GH treatment.

Perioperative neurocognitive disorders (PNDs) refer to a wide spectrum of cognitive impairment persisting days to even after a year postoperative with significant morbidity and mortality. However, despite much efforts involving perioperative managements, PNDs are still prevalent with no standard preventative and therapeutic strategy. To overcome PNDs, a better understanding of pathophysiology of PNDs is crucial and a large number of studies have proven that immune-inflammatory responses from surgical stress are involved in the abnormal activation of the hypothalamic-pituitary-adrenal (HPA) axis and destabilization of neurovascular unit (NVU) that lead to PNDs.

Background: Diagnosis and intervention of prediabetes is an emerging approach to preventing the progression and complications of diabetes. Inflammatory factors and dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis have been suggested as potential mechanisms underlying the pathogenesis of both diabetes and depression. However, the relationship between depression levels and the prevalence of prediabetes and its prognosis remains elusive.

Department of Radiation Oncology (Maastro), GROW Research Institute for Oncology and Reproduction, Maastricht University Medical Centre+, Maastricht, the Netherlands.
Background And Purpose: Radiotherapy for brain, head & neck (HN), and skull base (SB) tumors may deliver significant radiation dose to the hypothalamic-pituitary axis (HPA), leading to impaired functioning of this region and hence, to endocrine disorders. The purpose of this systematic review and -analysis is to investigate literature on HP dysfunction after radiation for non-pituitary brain, HN, or SB tumors at adult age, aiming to give insight in the prevalence of HP dysfunction related to radiation dose.
Materials And Methods: Literature search of the PubMed database was performed for HP dysfunction after radiotherapy in adult patients.
Dominant Expression of Chromogranin B in Pituitary Corticotrophs and Its Putative Role in Interaction With Secretogranin III.

SummaryPrevious studies have suggested that chromogranin A (CgA) is a partner molecule of secretogranin III (SgIII). In mouse pituitary corticotroph-derived AtT-20 cells, SgIII plays a role in sorting CgA/hormone aggregates into secretory granules (SGs). Although CgA expression is equivocal, CgB is clearly detectable in the rat pituitary corticotrophs.
