Pathological brain lesions in girls with central precocious puberty at initial diagnosis in Southern Vietnam.

Ann Pediatr Endocrinol Metab 2022 May 16. Epub 2022 May 16.

School of Nutrition and Health Sciences, Taipei Medical University, Taipei City, Taiwan.

Purpose: Cranial magnetic resonance imaging (MRI) is recommended to identify the existence of intracranial lesions in girls with central precocious puberty (CPP). Yet, the routine MRI scan in girls with CPP is still debatable, as the pathological finding in girls with CPP older than six years is limited. Therefore, we aimed to identify the prevalence of brain lessons stratified by age group (0-2, 2-6, and 6-8 years). Read More

Circulating Noncoding RNAs in Pituitary Neuroendocrine Tumors-Two Sides of the Same Coin.

Authors:
Henriett Butz

Int J Mol Sci 2022 May 4;23(9). Epub 2022 May 4.

Hereditary Tumours Research Group, Hungarian Academy of Sciences-Semmelweis University, H-1089 Budapest, Hungary.

Pituitary neuroendocrine tumors (PitNET) are common intracranial neoplasms. While in case of hormone secreting tumors pituitary hormone measurements can be used for monitoring the disease, in non-functional tumors there is a need to discover non-invasive biomarkers. Non-coding RNAs (ncRNAs) are popular biomarker candidates due to their stability and tissue specificity. Read More

The Genomic Landscape of Corticotroph Tumors: From Silent Adenomas to ACTH-Secreting Carcinomas.

Int J Mol Sci 2022 Apr 27;23(9). Epub 2022 Apr 27.

Unidad de Investigación Medica en Enfermedades Endocrinas, Hospital de Especialidades, Centro Medico Nacional Siglo XXI, Instituto Mexicano del Seguro Social, Ciudad de Mexico 06720, Mexico.

Corticotroph cells give rise to aggressive and rare pituitary neoplasms comprising ACTH-producing adenomas resulting in Cushing disease (CD), clinically silent ACTH adenomas (SCA), Crooke cell adenomas (CCA) and ACTH-producing carcinomas (CA). The molecular pathogenesis of these tumors is still poorly understood. To better understand the genomic landscape of all the lesions of the corticotroph lineage, we sequenced the whole exome of three SCA, one CCA, four ACTH-secreting PA causing CD, one corticotrophinoma occurring in a CD patient who developed Nelson syndrome after adrenalectomy and one patient with an ACTH-producing CA.

Immune checkpoint inhibitor-related hypophysitis.

Best Pract Res Clin Endocrinol Metab 2022 May 6:101668. Epub 2022 May 6.

Kobe University School of Medicine, 7-5-1, Kusunoki-cho, Chuo-ku, Kobe, 650-0017, Japan; Department of Diabetes and Endocrinology, Nara Medical University, 840 Shijo-cho, Kashihara, Nara, 634-8522, Japan.

Immune checkpoint inhibitors (ICIs) have been recently proposed as a strategy for treating anti-malignant neoplasms. However, this treatment leads to immune-related adverse events (irAEs) such as autoimmune endocrinopathy. Early diagnosis and appropriate treatment of ICI-related hypophysitis are essential as it can manifest as a life-threatening condition due to an adrenal crisis. Read More

Servicio de Endocrinología y Nutrición, Complejo Hospitalario de Navarra, Pamplona, Navarra, Spain.

Introduction: Serum cortisol levels within the first days after pituitary surgery have been shown to be a predictor of post-surgical adrenal insufficiency. However, the indication of empirical glucocorticoids to avoid this complication remains controversial. The objective is to assess the role of cortisol in the early postoperative period as a predictor of long-term corticotropic function according to the pituitary perisurgical protocol with corticosteroid replacement followed in our center.

Revisiting Surgery in the Current Era of Gamma Knife for Cavernous Sinus Lesions.

Neurol India 2022 Mar-Apr;70(2):563-573

Department of Neurosurgery, Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh, India.

Cureus 2022 Apr 7;14(4):e23928. Epub 2022 Apr 7.

Radiosurgery, International Cancer Center, Diagnostic Hospital, San Salvador, SLV.

Introduction The complex anatomy of the cavernous sinus confers a true challenge when it comes to safe tumor resection. Due to its non-invasive nature, stereotactic radiosurgery (SRS) is expected to have lower mortality and morbidity rates than microsurgery. The purpose of this study was to evaluate clinical results regarding visual symptoms after SRS for benign tumors invading the cavernous sinus. Read More

Impact of RSUME Actions on Biomolecular Modifications in Physio-Pathological Processes.

Front Endocrinol (Lausanne) 2022 21;13:864780. Epub 2022 Apr 21.

Instituto de Investigación en Biomedicina de Buenos Aires (IBioBA) - Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET) - Partner Institute of the Max Planck Society, Buenos Aires, Argentina.

The small RWD domain-containing protein called RSUME or RWDD3 was cloned from pituitary tumor cells with increasing tumorigenic and angiogenic proficiency. RSUME expression is induced under hypoxia or heat shock and is upregulated, at several pathophysiological stages, in tissues like pituitary, kidney, heart, pancreas, or adrenal gland. To date, several factors with essential roles in endocrine-related cancer appear to be modulated by RWDD3. Read More

Case Report: Micro-RNAs in Plasma From Bilateral Inferior Petrosal Sinus Sampling and Peripheral Blood From Corticotroph Pituitary Neuroendocrine Tumors.

Front Endocrinol (Lausanne) 2022 22;13:748152. Epub 2022 Apr 22.

Department of Molecular and Functional Genomics, Latvian Biomedical Research and Study Centre, Riga, Latvia.

Objective: Circulating miRNAs are found in bodily fluids including plasma and can serve as biomarkers for diseases. The aim of this study was to provide the first insight into the landscape of circulating miRNAs in close proximity to the adrenocorticotropic hormone (ACTH) secreting PitNET. To achieve this objective next-generation sequencing of miRNAs in plasma from bilateral inferior petrosal sinus sampling (BIPSS) - a gold standard in diagnosing ACTH-secreting PitNETs was carried out and selected miRNA candidates were further tested by RT-qPCR in independent patient cohorts.

Adamantinomatous craniopharyngioma cyst fluid can trigger inflammatory activation of microglia to damage the hypothalamic neurons by inducing the production of β-amyloid.

J Neuroinflammation 2022 May 7;19(1):108. Epub 2022 May 7.

Department of Neurosurgery, Nanfang Hospital, Southern Medical University, No. 1838, Guangzhou North Road, Guangzhou, Guangdong, China.

Introduction: The mechanism by which adamantinomatous craniopharyngioma (ACP) damages the hypothalamus is still unclear. Cyst fluid rich in lipids and inflammatory factors is a characteristic pathological manifestation of ACP and may play a very important role in hypothalamic injury caused by tumors.

Objective: The objective of this study was to construct a reliable animal model of ACP cyst fluid-induced hypothalamic injury and explore the specific mechanism of hypothalamic injury caused by cyst fluid. Read More

Best Pract Res Clin Endocrinol Metab 2022 Apr 26:101663. Epub 2022 Apr 26.

Nara Medical University, Department of Diabetes and Endocrinology, Japan. Electronic address:

Recent advances in tumor immunology have enabled to develop immune checkpoint inhibitors and to save many patients with advanced cancer. Various endocrine diseases are caused by autoimmune mechanisms; it is important to understand that many endocrine organs are targeted by autoimmunity. In addition, some of malignant tumors ectopically produce hormones and lead to a clinically relevant ectopic hormone syndrome as an endocrine paraneoplastic syndrome. Read More

Localization of TSH-secreting pituitary adenoma using 11C-methionine image subtraction.

EJNMMI Res 2022 May 7;12(1):26. Epub 2022 May 7.

Cambridge Endocrine Molecular Imaging Group, University of Cambridge, Addenbrooke's Hospital, Cambridge Biomedical Campus, Hills Road, Cambridge, CB2 0QQ, UK.

Background: Pituitary adenomas (PA) affect ~ 1:1200 of the population and can cause a wide range of symptoms due to hormone over-secretion, loss of normal pituitary gland function and/or compression of visual pathways, resulting in significantly impaired quality of life. Surgery is potentially curative if the location of the adenoma can be determined. However, standard structural (anatomical) imaging, in the form of MRI, is unable to locate all tumors, especially microadenomas (< 1 cm diameter). Read More
