Accuracy of the 10 μg desmopressin test for differential diagnosis of Cushing syndrome: a systematic review and meta-analysis.

Unlabelled: We evaluated the accuracy of the 10 μg desmopressin test in differentiating Cushing disease (CD) from non-neoplastic hypercortisolism (NNH) and ectopic ACTH syndrome (EAS). A systematic review of studies on diagnostic test accuracy in patients with CD, NNH, or EAS subjected to the desmopressin test obtained from LILACS, PubMed, EMBASE, and CENTRAL databases was performed. Two reviewers independently selected the studies, assessed the risk of bias, and extracted the data.

Adoption of Industry 4.0 technologies by organizations: a maturity levels perspective.

This study employs a structured literature analysis considering Industry 4.0 technologies and their adoption stages (intention, adoption, implementation, routinization, continuance, and diffusion). We identify the technology adoption stage for each technology type, which in turn supports a maturity level categorization, as well as future research suggestions and challenging open research questions.

Pregnancy after pituitary surgery does not influence the recurrence of Cushing's disease.

Purpose: Pregnancy is associated with the activation of the hypothalamus-pituitary-adrenal axis, which can cause a misdiagnosis of Cushing's syndrome. The aim of this study is to evaluate the impact of pregnancy after pituitary surgery on the recurrence rate in Cushing's disease (CD) patients.

Methods: This was a retrospective study in a tertiary center.

Supply chain resilience in the UK during the coronavirus pandemic: A resource orchestration perspective.

The COVID-19 pandemic caused significant disruptions to global operations and supply chains. While the huge impact of the pandemic has nurtured important literature over the last couple of years, little is being said about the role of resource orchestration in supporting resilience in highly disruptive contexts. Thus, this study aims to this knowledge gap by proposing an original model to explore supply chain resilience (SCRE) antecedents, considering supply chain alertness (SCAL) as a central point to support resilience.

The effects of cabergoline in the presurgical and recurrence periods of Cushing's disease patients.

Background: The dopaminergic agonist cabergoline (CAB) has been used in the pharmacological treatment of Cushing's disease (CD). The effect is attributed to the frequent expression of the dopamine receptor subtype 2 in corticotroph tumors. However, in-vivo studies have demonstrated the normalization of 24-h urinary cortisol (24-h UC) in approximately 30-40% of patients over the long term, mainly after surgical failure.

Resolution of Cyclicity After Pasireotide LAR in a Patient With Cushing Disease.

Objective: The cyclicity (CIC) of cortisol spontaneously occurs in a minority of patients with Cushing syndrome (CS). When it arises, diagnostic and therapeutic approaches become more challenging. This study aimed to report a patient with Cushing disease (CD) who achieved normalization of cortisol and CIC pattern with pasireotide long-acting release (pasi/LAR).

High accuracy of bilateral and simultaneous petrosal sinus sampling with desmopressin for the differential diagnosis of pediatric ACTH-dependent Cushing's syndrome.

Purpose: To analyze the bilateral and simultaneous petrosal sinus sampling (BIPSS) in a subgroup of children and adolescents with ACTH-dependent Cushing's syndrome (ADCS) METHODS: Retrospective study in a tertiary reference center. From 1993 and 2017, 19 children and adolescents (PED) were submitted to the BIPSS, median age of 14 years (range 9-19 years), 53% were males, 18 had Cushing's disease (CD) and one had ectopic ACTH syndrome (EAS). All procedures were performed with 10 µg of intravenous desmopressin.

Time to Diagnosis in Cushing's Syndrome: A Meta-Analysis Based on 5367 Patients.

Context: Signs and symptoms of Cushing's syndrome (CS) overlap with common diseases, such as the metabolic syndrome, obesity, osteoporosis, and depression. Therefore, it can take years to finally diagnose CS, although early diagnosis is important for prevention of complications.

Objective: The aim of this study was to assess the time span between first symptoms and diagnosis of CS in different populations to identify factors associated with an early diagnosis.

Cushing's disease due to somatic USP8 mutations: a systematic review and meta-analysis.

Purpose: Cushing's disease (CD) is a severe illness generally caused by microcorticotropinomas (MICs) and in approximately 7-20% of patients by macrocorticotropinomas (MACs). USP8-mutations have been identified as a major genetic cause of CD (~ 50%). Few studies have reported the distribution between MICs-MACs related to USP8-mutations and their genotype-phenotype correlations.

Filamin A and DRD2 expression in corticotrophinomas.

Purpose: Filamin A (FLNA) expression is related to dopamine receptor type 2 (DRD2) expression in prolactinomas. Nevertheless, in corticotrophinomas, there are few studies about DRD2 expression and no data on FLNA. Therefore, we evaluated FLNA and DRD2 expression in corticotrophinomas and their association with tumor characteristics.

Pregnancy in Patients with Cushing's Syndrome.

Progress in diagnosis and treatment of endocrine diseases has made pregnancy possible for women with endocrinopathies, including Cushing's syndrome (CS). The risk of maternal-fetal complications in patients who are not biochemically controlled, however, is substantial. Therefore, the surgical and/or medical control of hypercortisolism is mandatory prior to conceiving.

A review of Cushing's disease treatment by the Department of Neuroendocrinology of the Brazilian Society of Endocrinology and Metabolism.

The treatment objectives for a patient with Cushing's disease (CD) are remission of hypercortisolism, adequate management of co-morbidities, restoration of the hypothalamic-pituitary-adrenal axis, preservation of fertility and pituitary function, and improvement of visual defects in cases of macroadenomas with suprasellar extension. Transsphenoidal pituitary surgery is the main treatment option for the majority of cases, even in macroadenomas with low probability of remission. In cases of surgical failure, another subsequent pituitary surgery might be indicated in cases with persistent tumor imaging at post surgical magnetic resonance imaging (MRI) and/or pathology analysis of adrenocorticotropic hormone-positive (ACTH+) positive pituitary adenoma in the first procedure.

Uterine Artery Embolization and Surgical Methods for the Treatment of Symptomatic Uterine Leiomyomas: A Systemic Review and Meta-analysis Followed by Indirect Treatment Comparison.

Purpose: There is significant discussion and uncertainty about the optimal management of symptomatic uterine leiomyomas (SULs). Nonsurgical procedures such as uterine artery embolization (UAE) have been developed. The goal of this study was to conduct a meta-analysis and an indirect treatment comparison to examine the comparative efficacy and safety of the surgical procedures to treat SULs compared with UAE.

Transcriptome Analysis Showed a Differential Signature between Invasive and Non-invasive Corticotrophinomas.

ACTH-dependent hypercortisolism caused by a pituitary adenoma [Cushing's disease (CD)] is the most common cause of endogenous Cushing's syndrome. CD is often associated with several morbidities, including hypertension, diabetes, osteoporosis/bone fractures, secondary infections, and increased cardiovascular mortality. While the majority (≈80%) of the corticotrophinomas visible on pituitary magnetic resonance imaging are microadenomas (MICs, <10 mm of diameter), some tumors are macroadenomas (MACs, ≥10 mm) with increased growth potential and invasiveness, exceptionally exhibiting malignant demeanor.

Comparative effectiveness of interferons in relapsing-remitting multiple sclerosis: a meta-analysis of real-world studies.

Background: Differences between interferons have been evaluated for over 20 years. While randomized controlled trial (RCT) data is mainly used for assessments and strong data for causal inferences, it does not necessarily reflect everyday practice. Real-world data may provide additional information.

Choroidal and Retinal Abnormalities by Optical Coherence Tomography in Endogenous Cushing's Syndrome.

Context: Cortisol has been suggested as a risk factor for choroidal thickening, which may lead to retinal changes.

Objective: To compare choroidal thickness measurements using optical coherence tomography (OCT) in patients with endogenous active Cushing's syndrome (CS) and to evaluate the occurrence of retinal abnormalities in the same group of patients.

Design: Cross-sectional study.

Recommendations of the Neuroendocrinology Department of the Brazilian Society of Endocrinology and Metabolism for the diagnosis of Cushing's disease in Brazil.

Although it is a rare condition, the accurate diagnosis and treatment of Cushing's disease is important due to its higher morbidity and mortality compared to the general population, which is attributed to cardiovascular diseases, diabetes mellitus and infections. Screening for hypercortisolism is recommended for patients who present multiple and progressive clinical signs and symptoms, especially those who are considered to be more specific to Cushing's syndrome, abnormal findings relative to age (e.g.

Pregnancy and pituitary adenomas.

Infertility is frequent in patients harboring pituitary adenomas. The mechanisms involved include hypogonadism secondary to hormonal hypersecretion (prolactin, growth hormone and cortisol), stalk disconnection and pituitary damage. With the improvement of clinical and surgical treatment, pregnancy in women harboring pituitary adenomas turned into a reality.

RETRACTED ARTICLE: Fatal factitious Cushing syndrome (Münchhausen's syndrome) in a patient with macroprolactinoma and silent corticotrophinoma: case report and literature review.

Münchhausen's syndrome (MS) is a chronic factitious disorder characterized by the intentional production of clinical symptoms without external incentive. One type of MS is factitious Cushing syndrome, an extremely rare clinical situation in which the diagnosis is challenging mainly due to interference of the exogenous medication in cortisol immunoassays. We described a 26-year-old woman who was originally diagnosed with a macroprolactinoma and during follow-up developed clinical and laboratorial hypercortisolism.

Medical combination therapies in Cushing's disease.

Introduction: There has been growing interest on medical therapy for the management of Cushing's disease (CD), particularly in cases of persistent or recurrent hypercortisolism. Ketoconazole, an inhibitor of adrenal steroidogenesis, is the most widely used drug, whereas cabergoline and pasireotide are the most promising centrally acting agents. The main purpose of this review article is to highlight the options of medical treatment for CD, with a special emphasis on combination therapies, a topic that has only been addressed by a limited number of studies.

Persistence of intrasellar trigeminal artery and simultaneous pituitary adenoma: description of two cases and their importance for the differential diagnosis of sellar lesions.

Persistent trigeminal artery (PTA) is the most frequent embryonic communication between the carotid and vertebrobasilar systems. However, hormonal changes or the association of PTA with other sellar lesions, such as pituitary adenomas, are extremely rare. The aim of the present study was to report two patients with intrasellar PTA and simultaneous pituitary adenoma in order to emphasize the importance of differential diagnoses for sellar lesions.

p27 variant and corticotropinoma susceptibility: a genetic and in vitro study.

Germline mutations in p27(kip1) are associated with increased susceptibility to multiple endocrine neoplasias (MEN) both in rats and humans; however, the potential role of common polymorphisms of this gene in endocrine tumor susceptibility and tumorigenesis remains mostly unrecognized. To assess the risk associated with polymorphism rs2066827 (p27-V109G), we genotyped a large cohort of Brazilian patients with sporadic endocrine tumors (pituitary adenomas, n=252; pheochromocytomas, n=125; medullary thyroid carcinoma, n=51; and parathyroid adenomas, n=19) and 885 population-matched healthy controls and determined the odds ratios and 95% CIs. Significant associations were found for the group of patients with pituitary adenomas (P=0.

Spontaneous remission of hypercortisolism presumed due to asymptomatic tumor apoplexy in ACTH-producing pituitary macroadenoma.

Cushing's disease (CD) is usually caused by secretion of ACTH by a pituitary corticotroph microadenoma. Nevertheless, 7%-20% of patients present with ACTH-secreting macroadenomas. Our aim is to report a 36-year-old female patient with CD due to solid-cystic ACTH-macroadenoma followed up during 34 months.
