Increased cardiometabolic risk and prevalence of ascending aorta dilation in patients with nonfunctioning adrenal incidentaloma: a retrospective propensity score-matched study.

The cardiometabolic implications of Non-Functioning Adrenal Incidentaloma (NFAI) is still matter of debate. This study takes a novel approach to analyze this association, accounting for the influence of various confounding factors. We present the findings of a retrospective, cross-sectional, and case-control study.

Asymmetric and symmetric dimethylarginine as markers of endothelial dysfunction in cerebrovascular disease: A prospective study.

Background And Aim: Asymmetric dimethylarginine (ADMA) and symmetric dimethylarginine (SDMA) have been proposed as mediators of endothelial dysfunction. In this study, we aimed to investigate the diagnostic and prognostic role of ADMA and SDMA in acute cerebrovascular disease.

Methods And Results: A prospective case-control study was performed, enrolling 48 patients affected by ischemic stroke with no cardioembolic origin, 20 patients affected by TIA, 40 subjects at high cardiovascular risk and 68 healthy subjects.

Pathophysiology and Management of Glycemic Alterations before and after Surgery for Pheochromocytoma and Paraganglioma.

Glycemic alterations are frequent in patients with pheochromocytoma and paraganglioma (PPGL), but the real incidence of secondary diabetes mellitus (DM) is uncertain, because prospective multicenter studies on this topic are lacking in the literature. The main pathophysiological mechanisms of glucose homeostasis alterations in PPGL, related to catecholamine hypersecretion, are impaired insulin and glucagon-like peptide type 1 (GLP-1) secretion and increased insulin resistance. Moreover, it has been reported that different pathways leading to glucose intolerance may be related to the secretory phenotype of the chromaffin tumor.

Resistance to Somatostatin Analogs in Italian Acromegaly Patients: The MISS Study.

Approximately 60% of acromegaly patients are not adequately controlled by first-generation somatostatin receptor ligands. This multicenter retrospective study aimed to identify the most relevant biomarkers specific for the Italian acromegaly population. Resistant patients were enrolled consecutively based on time of neurosurgery, while responders were collected in a 1:2 ratio.

Clinical and Pathological Tools for Predicting Recurrence and/or Metastasis in Patients with Pheochromocytoma and Paraganglioma.

Pheochromocytomas and paragangliomas are endocrine tumors belonging to the family of neural crest cell-derived neoplasms. They have an extremely variable clinical course, characterized by a non-negligible percentage of relapse and/or metastasis after radical surgery. To date, there are no reliable methods to predict the metastatic potential of these neoplasms, despite several clinical, molecular, and histopathological factors that have been extensively studied in the literature as predictors of the recurrence and/or metastasis in these neoplasms with different performances and results.

Galectin-3 and Estrogen Receptor Alpha as Prognostic Markers in Prolactinoma: Preliminary Results From a Pilot Study.

Introduction: Prolactin-secreting pituitary tumors (PRL-omas) are generally benign neoplasia. However, a percentage of cases show aggressive behavior. Prognostic markers may allow for the identification of aggressive cases.

Association of Urine Metanephrine Levels with CardiometaBolic Risk: An Observational Retrospective Study.

No research has explored the role of catecholamine metabolites in the stratification of cardiovascular risk. We aimed to evaluate the relationship between urine metanephrines and cardiometabolic risk/complications. In this retrospective cross-sectional study, we collected the data of 1374 patients submitted to the evaluation of urine metanephrines at the City of Health and Science University Hospital of Turin between 2007 and 2015, mainly for investigating the suspicion of secondary hypertension or the secretion of an adrenal lesion.

Morning Serum Cortisol Level Predicts Central Adrenal Insufficiency Diagnosed by Insulin Tolerance Test.

Introduction: According to guidelines, a morning serum cortisol level <83 nmol/L is diagnostic for central adrenal insufficiency (CAI), a value >414 nmol/L excludes CAI, while values between 83 and 414 nmol/L require stimulation tests. However, there are no currently reliable data on morning serum cortisol for prediction of cortisol response to insulin tolerance test (ITT).

Objective: Using the receiver-operating characteristic curve analysis, the purpose of this study was to detect the morning serum cortisol cutoff with a specificity (SP) or a sensitivity (SE) above 95% that identify those patients who should not be tested with ITT.

Tumour-infiltrating cytotoxic T lymphocytes in somatotroph pituitary neuroendocrine tumours.

Introduction: Somatotroph pituitary tumours are often resistant to first-generation somatostatin analogues and can invade the surrounding structures, limiting the chances of curative surgery. Recent studies suggested that the immune microenvironment and pro-angiogenic factors can influence neuroendocrine tumour prognosis. In this study, we aimed to investigate the prognostic role of immune cell-specific markers and endocan, a proteoglycan involved in neoangiogenesis and cell adhesion, in a cohort of acromegaly patients who underwent pituitary surgery as first-line treatment.

Effects of Pegvisomant and Pasireotide LAR on Vertebral Fractures in Acromegaly Resistant to First-generation SRLs.

Purpose: Osteopathy is an emerging complication of acromegaly. In somatostatin receptor ligands (SRL)-resistant patients, pegvisomant (PegV) and pasireotide LAR (Pasi) are used for acromegaly treatment, but their effect on skeletal health is still not defined.

Methods: In a longitudinal retrospective international study, we evaluated incidence of radiological vertebral fractures (VFs) in 55 patients with acromegaly resistant to first-generation SRL.

Synchronous bilateral adrenalectomy in ACTH-dependent hypercortisolism: predictors, biomarkers and outcomes.

Introduction: Hypercortisolism requires a prompt therapeutic management to reduce the risk of development of a potential fatal emergency. A synchronous bilateral adrenalectomy (SBA) is effective in recovering hypercortisolism. However, specific indications for an SBA are not available.

Pasireotide and Pegvisomant Combination Treatment in Acromegaly Resistant to Second-Line Therapies: A Longitudinal Study.

Context: The treatment of acromegaly resistant to first- and second-line therapies can be extremely challenging.

Design: We have described six patients who were successfully treated with a combination therapy of pasireotide and pegvisomant and compared them with a control group of patients resistant to conventional somatostatin analogs (SSAs), whose disease was controlled with other treatment, such as pasireotide (as monotherapy) or pegvisomant (as monotherapy or combined with conventional SSAs).

Results: In these six patients, acromegaly was controlled with combined pasireotide and pegvisomant treatment after failure of all other treatments.

Short- and long-term responsiveness to low dose growth hormone (GH) in adult GH deficiency: Role of GH receptor polymorphism.

In patients with growth hormone (GH) deficiency (GHD), low doses of recombinant human GH (rhGH) have a similar or better long-term clinical effect than higher doses. Pharmacogenetic studies suggest that GH receptor (GHR) polymorphism only influences some metabolic parameters. Nonetheless, there is no clear scientific evidence proving the effects of lower rhGH dose regimens on metabolic parameters.

Prevalence of morphometric vertebral fractures in "difficult" patients with acromegaly with different biochemical outcomes after multimodal treatment.

Introduction: Skeletal fragility with high risk of vertebral fractures is an emerging complication of acromegaly in close relationship with duration of active disease. The aim of this cross-sectional study was to evaluate the prevalence and determinants of vertebral fractures in males and females with a history of long-standing active acromegaly undergoing treatment with Pegvisomant.

Subjects And Methods: Thirty-eight patients (25 females, 13 males) with acromegaly under Pegvisomant therapy were evaluated for vertebral fractures and bone mineral density at lumbar spine and femoral neck.

Enhanced recovery pathway in elderly patients undergoing colorectal surgery: is there an effect of increasing ages? Results from the perioperative Italian Society Registry.

Previous studies reported that enhanced recovery pathway (ERP) is safe in elderly who did not require a specifically tailored protocol. In previous studies, elderly have been considered as a homogeneous cohort and the cut-off value to identify them was different. The aim of the present study is to assess the compliance to ERP and its impact on postoperative outcome in three subgroups of elderly patients with increasing ages.

Understanding the effect of acromegaly on the human skeleton.

Acromegaly, caused in most cases by Growth Hormone (GH)-secreting pituitary adenomas, is characterized by increased skeletal growth and enlargement of the soft tissue, because GH and its effector Insulin-like Growth factor-1 are important regulators of bone homeostasis and have a central role in the longitudinal bone growth and maintenance of bone mass. Areas covered: Despite the anabolic effect of these hormones is well known, as a result of the stimulation of bone turnover and especially of bone formation, many acromegalic patients are suffering from a form of secondary osteoporosis with increased risk of fractures. Expert commentary: In this review, we summarize the pathophysiology, diagnosis, clinical picture, disease course and management of skeletal complications of acromegaly, focusing in particular on secondary osteoporosis and fracture risk in acromegaly.

Laparoscopy as a prognostic factor in curative resection for node positive colorectal cancer: results for a single-institution nonrandomized prospective trial.

Background: Several studies reporting preliminary long-term survival data after laparoscopic resections for colonic adenocarcinoma did not show any detrimental effect in comparison with historic studies of laparotomies. A previous randomized study has reported an unforeseen better long-term survival for node-positive patients treated by laparoscopic colectomy.

Methods: A single-institution prospective nonrandomized trial compared short- and long-term results of laparoscopic and open curative resection for adenocarcinoma of the left colon or rectum in 255 consecutive patients from January 1996 to December 2000.

[Palliative endoscopic intubation of esophago-gastric neoplastic stenosis: analysis of factors that may influence immediate results].

The paper examines a series of 172 patients undergoing endoscopic intubation with plastic stent due to unoperable esophago-gastric tumoral stenoses during the period 1980-1991. An analysis of the data enabled the following conclusions to be drawn: (1) The majority of perforations occur during the treatment of distal stenoses (15%), anastomotic stenosis (20%) and extrinsic compression stenoses (23% vs 7% in the case of stenosing primary esophageal neoplasia). (2) Severe respiratory problems may occur during treatment of cervical stenoses.
