Central diabetes insipidus (vasopressin deficiency) after surgery for pituitary tumours: a systematic review and meta-analysis.

Objective: Central diabetes insipidus or vasopressin deficiency (AVP-D) is the most frequent water balance disorder after transsphenoidal surgery (TSS) with variable prevalence amongst studies. We aimed to determine rates of newly developed transient or permanent AVP-D in patients with pituitary tumours treated with TSS.

Design And Methods: We performed systematic review of Medline, Embase, and Cochrane Library between January 1, 2000 and January 31, 2021 for studies reporting on outcomes for pituitary adenoma, craniopharyngioma, and Rathke's cleft cyst (RCC) after TSS and providing definition of post-operative AVP-D.

UK practice on incidentally detected non-functioning pituitary microadenomas: analysis of two national surveys during a 12-year interval.

Purpose: The optimal management approach for presumed non-functioning pituitary microadenomas (microNFPAs) remains unclear. Our aim was to capture current UK practice and identify changes with time.

Methods: Two online surveys investigating clinicians' approaches were performed in 2009-2010 and 2021-2022 (advertised through Society for Endocrinology UK).

Management of Nelson's Syndrome.

Nelson's syndrome is a potentially severe condition that may develop in patients with Cushing's disease treated with bilateral adrenalectomy. Its management can be challenging. Pituitary surgery followed or not by radiotherapy offers the most optimal tumour control, whilst pituitary irradiation alone needs to be considered in cases requiring intervention and are poor surgical candidates.

Pre- and peri-operative characteristics, complications and outcomes of patients with biochemically silent pheochromocytomas; a case series.

Purpose: Pheochromocytomas are rare tumors and biochemically silent ones with normal catecholamine levels are even rarer. Up to date, biochemically inactive pheochromocytomas are poorly investigated. We aimed to systematically assess the pre- and peri-operative characteristics and the outcomes of patients with these tumors who had been treated and followed-up in 2 tertiary centers.

The diagnosis and management of Cushing's syndrome in pregnancy.

Endogenous Cushing's syndrome (CS) is rarely encountered during pregnancy. Clinical and biochemical changes in healthy pregnancy overlap with those seen in pregnancy complicated by CS; the diagnosis is therefore challenging and can be delayed. During normal gestation, adrenocorticotrophic hormone, corticotrophin-releasing hormone, cortisol, and urinary free cortisol levels rise.

Nelson's Syndrome: An Update.

Nelson's syndrome (NS) is a condition which may develop in patients with Cushing's disease after bilateral adrenalectomy. Although there is no formal consensus on what defines NS, corticotroph tumor growth and/or gradually increasing ACTH levels are important diagnostic elements. Pathogenesis is unclear and well-established predictive factors are lacking; high ACTH during the first year after bilateral adrenalectomy is the most consistently reported predictive parameter.

Outcomes of Patients with Nelson's Syndrome after Primary Treatment: A Multicenter Study from 13 UK Pituitary Centers.

Context: Long-term outcomes of patients with Nelson's syndrome (NS) have been poorly explored, especially in the modern era.

Objective: To elucidate tumor control rates, effectiveness of various treatments, and markers of prognostic relevance in patients with NS.

Patients, Design, And Setting: Retrospective cohort study of 68 patients from 13 UK pituitary centers with median imaging follow-up of 13 years (range 1-45) since NS diagnosis.

Opioid-induced endocrinopathies.

The use of opioids is becoming a global epidemic, leading to a rise in the occurrence and recognition of the effects of opioid drugs on the endocrine system. Nonetheless, opioid-induced endocrinopathies still remain underdiagnosed, mainly because of symptom under-reporting by patients and poor clinician awareness. Hypogonadism is the most well recognised consequence of opioid use, but the inhibitory effects of opioid drugs on the hypothalamo-pituitary-adrenal axis and their negative effects on bone health also require attention.

Recurrence in silent corticotroph adenomas after primary treatment: A systematic review and meta-analysis.

Context: 2017 WHO Classification of Pituitary Tumors grades silent corticotroph adenomas (SCAs) as "high-risk adenomas" due to their aggressive clinical behavior (high probability of recurrence). However, studies comparing recurrence rates of SCAs with other non-functioning pituitary adenoma (NFPAs) subtypes have provided conflicting results.

Objective: Estimate recurrence rates of SCAs after primary treatment (surgery±radiotherapy) and recurrence rate ratios (RRR) between SCAs and other NFPA subtypes.

MECHANISMS OF ENDOCRINOLOGY: Endocrinology of opioids.

The use of opioids has grown substantially over the past two decades reaching the dimensions of a global epidemic. These drugs have effects on multiple levels of the endocrine system through mechanisms which are still not fully elucidated, and awareness of their endocrine sequelae is vital for all specialists prescribing or managing patients on them. Hypogonadism is the most well-recognised consequence of opioid use (prevalence 21–86%) which, however, may remain undiagnosed with potential adverse outcomes for the patients.

Branched-Chain Amino Acid Database Integrated in MEDIPAD Software as a Tool for Nutritional Investigation of Mediterranean Populations.

Branched-chained amino acids (BCAA) are essential dietary components for humans and can act as potential biomarkers for diabetes development. To efficiently estimate dietary intake, we developed a BCAA database for 1331 food items found in the French Centre d'Information sur la Qualité des Aliments (CIQUAL) food table by compiling BCAA content from international tables, published measurements, or by food similarity as well as by calculating 267 items from Greek, Turkish, Romanian, and Moroccan mixed dishes. The database embedded in MEDIPAD software capable of registering 24 h of dietary recalls (24HDR) with clinical and genetic data was evaluated based on archived 24HDR of the Saint Pierre Institute (France) from 2957 subjects, which indicated a BCAA content up to 4.

Impact of menopause on outcomes in prolactinomas after dopamine agonist treatment withdrawal.

Objective: Discontinuation of dopamine agonist (DA) treatment in women with prolactinoma after menopause is a potential approach; studies systematically assessing long-term outcomes are lacking. Our aim was to investigate the natural history of prolactinoma in this group.

Design/patients: Retrospective cohort study of women with prolactinoma diagnosed before menopause and who after menopause were not on DA.

A rare challenging case of co-existent craniopharyngioma, acromegaly and squamous cell lung cancer.

Unlabelled: Co-existence of craniopharyngioma and acromegaly has been very rarely reported. A 65-year-old man presented with visual deterioration, fatigue and frontal headaches. Magnetic resonance imaging revealed a suprasellar heterogeneous, mainly cystic, 1.

Mortality in patients with non-functioning pituitary adenoma.

Non-functioning pituitary adenomas (NFA) are benign pituitary neoplasms not associated with clinical evidence of hormonal hypersecretion. A substantial number of patients with NFA have morbidities related to the tumor and possible recurrence(s), as well as to the treatments offered. Studies assessing the long-term mortality of patients with NFA are limited.

Familial partial lipodystrophy and proteinuric renal disease due to a missense c.1045C > T mutation.

Unlabelled: Proteinuric renal disease is prevalent in congenital or acquired forms of generalized lipodystrophy. In contrast, an association between familial partial lipodystrophy (FPLD) and renal disease has been documented in very few cases. A 22-year-old female patient presented with impaired glucose tolerance, hyperinsulinemia, hirsutism and oligomenorrhea.

Idiopathic and normal lateral lumbar curves: muscle effects interpreted by 12th rib length asymmetry with pathomechanic implications for lumbar idiopathic scoliosis.

Background: The historical view of scoliosis as a primary rotation deformity led to debate about the pathomechanic role of paravertebral muscles; particularly multifidus, thought by some to be scoliogenic, counteracting, uncertain, or unimportant. Here, we address lateral lumbar curves (LLC) and suggest a pathomechanic role for quadrates lumborum, (QL) in the light of a new finding, namely of 12th rib bilateral length asymmetry associated with idiopathic and small non-scoliosis LLC.

Methods: Group 1: The postero-anterior spinal radiographs of 14 children (girls 9, boys 5) aged 9-18, median age 13 years, with right lumbar idiopathic scoliosis (IS) and right LLC less that 10°, were studied.

Tyrosine Kinase Inhibitors and Diabetes: A Novel Treatment Paradigm?

Deregulation of protein tyrosine kinase (PTK) activity is implicated in various proliferative conditions. Multi-target tyrosine kinase inhibitors (TKIs) are increasingly used for the treatment of different malignancies. Recently, several clinical cases of the reversal of both type 1 and 2 diabetes mellitus (T1DM, T2DM) during TKI administration have been reported.

Cushing's Syndrome Due to CRH and ACTH Co-secreting Pancreatic Tumor--Presentation of a New Case Focusing on Diagnostic Pitfalls.

Cushing's syndrome (CS) due to a corticotropin-releasing hormone (CRH) and adrenocorticotropin hormone (ACTH) co-secreting tumor is very rare, and diagnosis can be difficult. We describe a case of CS caused by ectopic CRH and ACTH production from a pancreatic neuroendocrine tumor (pNET) and discuss possible pitfalls in the diagnosis. A 48-year-old woman presented with gradual increase in body weight, muscle weakness, and difficult to control hypertension.
