The management of hypopituitarism in this group of patients is a challenging task. A correct diagnosis, which represents an essential requisite for an appropriate medical treatment, can be difficult because of the physiological changes occurring in pituitary function with aging, which may lead to challenges in the interpretation of laboratory results. Furthermore, the treatment requires several careful considerations: the need to restore the hormonal physiology with replacement therapies must be balanced with the need to avoid the risks of the over-replacement, especially in the presence of concomitant cardiovascular and metabolic disease. Interactions with other drugs able to modify the absorption and/or the metabolism of hormonal replacement therapies should be considered, in particular for the treatment of hypoadrenalism and hypothyroidism. The most important challenges stem from the lack of specific studies focused on the management of hypopituitarism in older people.Keywords: hypopituitarism, elderly, levothyroxine, glucocorticoid replacement therapy, recombinant GH, testosterone, central hypothyroidism, central hypoadrenalism, GH deficiency, central hypogonadism

Space exploration requires reliable, rapid, significant and safe methods for preventing, monitoring and controlling biocontamination risk in water loops and humid areas in manned Space habitats. Water is one of the most important resources of our everyday life. Its microbiological control in houses, public water dispensers and special conditions (e.g.: epidemics, catastrophes, isolation) is crucial. The presented solution is automated, compact and portable, and above all "integrated" -- i.e.: composed of modules working in synergy (prevention, monitoring, control and decontamination). It was designed for space applications, thus microgravitycompatible. BIOWYSE integrated system combines biostatic/biocide action with real-time biomonitoring and almost instantaneous UV-based disinfection. It is an automated and compact system, meaning low crew time need and suitable transportability. In an automated way, the Prevention Module prevents biofilm formation and the Decontamination Module immediately counteracts water microbial load increment upon checks by the Monitoring Module. BIOWYSE has full potential for exploitation for ISS and future manned Space Exploration missions and represents an innovative tool with a wide application potential in a large number of situations on Earth.

Background Thyroid-stimulating hormone (TSH) receptor (TSHR) autoantibodies (TRAbs) are a heterogeneous group of antibodies (Abs) with different functionalities. Among all TRAbs, only the stimulating ones (S-TRAbs) are considered as the pathogenetic marker of Graves' disease (GD). To date, the methods available for TRAbs testing are based on immunoassays (IMAs) which detect total serum TRAbs or bioassays which are not suitable in clinical practice, even though they discern Abs functionality. The aim of our work was to evaluate the analytical and clinical performance of a very recent IMA (Immulite TSI method), supposed to test only the serum concentration of S-TRAbs, in comparison with a current method for total TRAbs (Roche/Elecsys IMA). Methods We evaluated serum samples of 145 subjects: 46 with untreated (GD), 36 with chronic autoimmune thyroiditis, 3 with atrophic thyroiditis, 10 with multinodular non-toxic goiter and 50 healthy subjects. Results The method showed an optimal analytical sensitivity and high precision levels (LoB: 0.04 UI/L, LoD:0.07 UI/L, LoQ:0.14 UI/L, intra-assay CV: 4.2-5.9%, inter-assay: 4.5-7.2%). By receiver operating characteristics curve analysis, we obtained a value of 0.57 (sensitivity: 98.0%, specificity: 99.9%) as the best cut-off to distinguish GD, apart from four cases. Passing Bablok regression and Bland Altman analysis pointed out a good correlation and agreement with Roche method (R2 = 0.98, slope = 1.03, bias = -2.70). Conclusions The new method presents very promising analytical characteristics and could be adopted in clinical practice for GD diagnosis. Moreover, the test allows to accurately detect very low values of analyte with a further clinical utility in detecting earlier possible relapses. [ABSTRACT FROM AUTHOR]

Summary Background Occurrence of severe asthma exacerbations are the cornerstone of the evaluation of asthma management, but severe asthma exacerbations are rare events. Therefore, trials that assess drug efficacy on exacerbations are done late in clinical development programmes. We aimed to establish an endpoint capturing clinically relevant deteriorations (diary events) that, when combined with severe exacerbations, create a composite outcome (CompEx). CompEx needs to strongly mirror results seen with the severe exacerbation-validated outcome, to allow the design of clinical trials of shorter duration and that include fewer patients than trials assessing severe exacerbations. Methods Data from 12 asthma trials of 6 months or 12 months duration and, with standardised collection of exacerbations and diary card variables, were used to construct and test CompEx. The study populations had a mean age of 35–53 years, 59–69% were female, and had a mean FEV 1 percentage of predicted normal of 63–84%. With data from five trials, we established a series of diary events based on peak expiratory flow (P), reliever use (R), symptoms (S), awakenings (A), and threshold values for change from baseline and slopes to assess trends. For the development phase, we evaluated different variable combinations and deterioration criteria to select the most robust algorithm to define a diary event for the composite outcome. We defined a composite outcome, CompEx, as first occurrence of a diary event or a severe exacerbation. We assessed the performance of CompEx in seven trials by comparing the event frequency, treatment effect (hazard ratio; HR), and the sample size needed for future trials for the CompEx versus episodes of severe exacerbations. Findings CompEx (based on PRS) was the algorithm that best fulfilled our two-set criteria. When censored at 3 months, CompEx resulted in 2·8 times more events than severe exacerbations, and while preserving the treatment effect observed on severe exacerbations (CompEx over severe exacerbation average HR 1·01). The increased number of events, together with the sustained treatment effect, resulted in a large net gain in power, with a 67% mean reduction in the number of patients required in a drug trial for severe exacerbations. In six of seven comparisons tested, CompEx reduced the sample size needed by at least 50%. Validation of independent test populations confirmed the ability of CompEx to increase event frequencies, preserve treatment effect, and reduce the number of patients needed. Interpretation CompEx is a composite outcome for evaluation of new asthma therapies. CompEx allows design of shorter trials that require fewer patients than studies of severe exacerbations, while preserving the ability to show a treatment effect compared with severe exacerbations.

Summary Background The short-term benefits of inhaled corticosteroids for patients with chronic obstructive pulmonary disease (COPD) are greater in patients with evidence of eosinophilic airway inflammation. We investigated whether blood eosinophil count is a useful biomarker of the long-term effect of the inhaled corticosteroid fluticasone furoate on exacerbation frequency. Methods We did a post-hoc analysis of data from two replicate, randomised, double-blind trials of 12 months' duration (Sept 25, 2009 to Oct 21, 2011 and Oct 17, 2011) in which once a day vilanterol 25 μg was compared with 25 μg vilanterol plus 50 μg, 100 μg, or 200 μg fluticasone furoate in patients with moderate-to-severe COPD and a history of one or more exacerbation in the previous year. We compared exacerbation rates according to two baseline eosinophil cell count strata (<2% and ≥2%), and according to four baseline percentage groupings. We also assessed lung function and incidence of pneumonia per strata in treatment groups. Findings We included 3177 patients in the analyses, with 2083 patients (66%) having an eosinophil count of 2% or higher at study entry. Across all doses of inhaled corticosteroids, fluticasone furoate and vilanterol reduced exacerbations by 29% compared with vilanterol alone (mean 0·91 vs 1·28 exacerbations per patient per year; p<0·0001) in patients with eosinophil counts of 2% or higher, and by 10% (0·79 vs 0·89; p=0·2827) in patients with eosinophil counts lower than 2%. Reductions in exacerbations with fluticasone furoate and vilanterol, compared with vilanterol alone, were 24% in patients with baseline eosinophil counts of ≥2–<4%, 32% for those with counts of 4–<6%, and 42% for those with eosinophil counts of ≥6%. In patients treated with vilanterol alone, exacerbation rates increased progressively with increasing eosinophil count percentage category. Improvement in trough forced expiratory volume in 1 s (FEV 1 ) and the increased risk of pneumonia with fluticasone furoate and vilanterol compared with vilanterol alone were not associated with eosinophil count. Interpretation Blood eosinophil count is a promising biomarker of response to inhaled corticosteroids in patients with COPD. Blood eosinophil count could potentially be used to stratify patients for different exacerbation rate reduction strategies. Funding GlaxoSmithKline (study ID 201595). [ABSTRACT FROM AUTHOR]

Summary: Introduction: We assessed the utility of EBC pH as a biomarker in COPD in a large cohort of well-characterised individuals with COPD and control subjects from the Evaluation of COPD Longitudinally to Identify Predictive Surrogate Endpoints (ECLIPSE) study. We also determined short term reproducibility and the response of EBC to oral prednisolone. Methods: EBC was collected with R-TubesTM, using techniques for sampling and measurement that have been shown to be reproducible. Results: EBC pH was lower in COPD (n = 676, 7.29 ± SD 0.60) and in smoking controls (n = 31, 7.18 ± 0.85), compared with non-smoking controls (n = 50, 7.59 ± 0.44, p = 0.0008 and 0.0033 respectively), but was not different between COPD and smoking controls. There was no relationship between EBC pH and disease severity, as assessed by the percent predicted FEV1, nor with airway inflammation as assessed by sputum leukocyte counts. Treatment with 20 mg.day-1 prednisolone for 4 weeks did not change EBC pH. Conclusion: EBC pH is lower in COPD than in healthy control non-smokers, but does not differentiate COPD from smokers without COPD, relate to disease severity or to airway inflammation, and does not respond to corticosteroids. EBC pH therefore does not appear to be a useful biomarker in COPD. [ABSTRACT FROM AUTHOR]

Vasomotor rhinitis (VMR) is a common but poorly understood disorder of which there are two major subgroups: VMRw/t, triggered by weather/temperature and VMRir, triggered by airborne irritants. No specific biological pathways or specific treatments for VMRw/t or VMRir have been identified. However, intranasal corticosteroids (INSs) are effective in treating many forms of nonallergic rhinitis that include these conditions. A recently introduced INS with established efficacy in allergic rhinitis and enhanced affinity, fluticasone furoate, may possess the potency and safety profile required to treat chronic VMRw/t. Two replicate studies (FFR30006 and FFR30007) were conducted in six countries to evaluate the efficacy and safety of fluticasone furoate nasal spray in subjects with VMRw/t. After a 7- to 14-day screening period, subjects (n = 699) with symptomatic VMRw/t received fluticasone furoate, 110 μg q.d. or placebo for 4 weeks in these two randomized, double-blind, parallel-group studies. Subjects rated their nasal symptoms (congestion, rhinorrhea, and postnasal drip) twice daily on a 4-point categorical scale and evaluated their overall response to treatment at study end. Fluticasone furoate did not significantly improve daily reflective total nasal symptom scores, the primary end point, versus placebo (p = 0.259) and there was no improvement in any other measure of efficacy. The active treatment was well tolerated. Fluticasone furoate was not effective in treating subjects with a newly defined condition, weather-sensitive VMR. These unexpected results suggest that VMRw/t is a distinct subgroup of VMR that is refractory to treatment with INSs. Additional study of other treatments for VMRw/t (including INSs) is warranted.

Currently available metered dose inhalers (MDIs) do not track the remaining number of doses, indicating the need for a device that accurately monitors medication use. In an open-label study at 37 outpatient centers, patients ≥4 years old with asthma or chronic obstructive pulmonary disease requiring short-acting β2-agonists received two actuations of albuterol hydrofluoroalkane (HFA) [Ventolin HFA: GlaxoSmithKline], 90 μg twice daily, via a novel MDI with an integrated dose counter until all 200 actuations were completed. Concordance between counter readings, diary card–recorded actuations, and canister weights were measured in patients who completed ≥90% of the labeled actuations (n = 224). Adverse events and patient satisfaction were assessed in the intent-to-treat population (n = 268). In 43,865 recorded actuations, 333 counter versus diary discrepancies occurred (discrepancy rate of 0.76%), and 88% of discrepancies were by one to two actuations. Forty-seven percent of patients had no discrepancies. Incidence of the device firing without changes in counter readings was very low (0.09%). Mean expected actuations based on canister weights (184) were slightly lower than mean counter and diary-reported actuations (200 each). At baseline, 62% of patients reported anxiety about not knowing the quantity of medication remaining in their inhaler. On study completion, 92% expressed satisfaction with the dose counter and 92% agreed it would help prevent them from running out of medication. The adverse event profile showed that albuterol HFA was well tolerated. Integrated MDI counters are a useful and reliable tool for tracking a patient's medication supply. [ABSTRACT FROM AUTHOR]

Background: An important step toward understanding the biological mechanisms underlying a complex disease is a refined understanding of its clinical heterogeneity. Relating clinical and molecular differences may allow us to define more specific subtypes of patients that respond differently to therapeutic interventions. Results: We developed a novel unbiased method called diVIsive Shuffling Approach (VIStA) that identifies subgroups of patients by maximizing the difference in their gene expression patterns. We tested our algorithm on 140 subjects with Chronic Obstructive Pulmonary Disease (COPD) and found four distinct, biologically and clinically meaningful combinations of clinical characteristics that are associated with large gene expression differences. The dominant characteristic in these combinations was the severity of airflow limitation. Other frequently identified measures included emphysema, fibrinogen levels, phlegm, BMI and age. A pathway analysis of the differentially expressed genes in the identified subtypes suggests that VIStA is capable of capturing specific molecular signatures within in each group. Conclusions: The introduced methodology allowed us to identify combinations of clinical characteristics that correspond to clear gene expression differences. The resulting subtypes for COPD contribute to a better understanding of its heterogeneity.

Background: Approximately 5% to 10% of asthmatic patients achieve incomplete symptom control on current therapies. The association of IL-13 with asthma pathology and reduced corticosteroid sensitivity suggests a potential benefit of anti–IL-13 therapy in refractory asthma. GSK679586, a humanized mAb, inhibits IL-13 binding to both IL-13 receptor α1 and α2. Objectives: We sought to evaluate the efficacy and safety of GSK679586 in patients with severe asthma refractory to maximally indicated doses of inhaled corticosteroids. Methods: Patients who remained symptomatic (Asthma Control Questionnaire score ≥1.5) after uptitration to 1000 μg/d fluticasone propionate or greater were randomized to 3 once-monthly intravenous infusions of 10 mg/kg GSK679586 (n = 99) or placebo (n = 99). Results: Treatment differences in adjusted mean change from baseline over 12 weeks were nonsignificant for Asthma Control Questionnaire symptom scores (the primary end point; GSK679586 = −0.31, placebo = −0.17, P = .058) and FEV1 (GSK679586 = −0.01, placebo = 0.03, P = .276). Similar analyses in patients with increased serum IgE levels, blood eosinophil counts, or both were also negative. Incidence of asthma exacerbations was similar between treatments. Most adverse events were nonserious and unrelated to treatment. Two GSK679586-treated patients had treatment-related serious adverse events (lethargy and supraventricular extrasystoles). Conclusions: Although well tolerated, GSK679586 did not demonstrate clinically meaningful improvements in asthma control, pulmonary function, or exacerbations in patients with severe asthma. Further studies are needed to determine whether therapies targeting IL-13, the functionally related IL-4 cytokine, or both can provide clinical benefit in patients with severe refractory asthma or a subpopulation of these patients beyond that achievable with high-dose corticosteroids.

The Anthropocene era is marked by unprecedented human-induced alterations to the environment, resulting in a climate emergency and widespread ecological deterioration. A staggering number of up to one million species of plants and animals are in danger of becoming extinct, which includes over 10 % of insect species and 40 % of plant species. Unrestrained release of greenhouse gases, widespread deforestation, intense agricultural practices, excessive fishing, and alterations in land use have exceeded the ecological boundaries that were once responsible for humanity's wellbeing. As per the Intergovernmental Panel on Climate Change (IPCC), existing policies are expected to result in a minimum rise in global temperature of +2 °C, with more recent assessments indicating a potential increase of up to +2.9 °C. The effects of climate change and ecological degradation on the formation of diseases are complex and have multiple aspects. Deforestation diminishes biodiversity and compels wildlife to come into greater proximity with humans, hence promoting the transmission of zoonotic diseases. Climate change intensifies these impacts by modifying the habitats of disease carrying organisms, resulting in the expansion of vector-borne diseases such as malaria, dengue, and Zika virus into previously unaffected areas. Furthermore, climate change amplifies the occurrence and severity of extreme weather phenomena, which undermines water, sanitation, and hygiene (WASH) practices. This creates an environment conducive to the transmission of waterborne diseases such as cholera in densely populated resettlement camps. Climate-induced disasters contribute to the complexity of epidemiological landscapes, exacerbating antimicrobial resistance and posing a threat to modern medical advancements. This narrative review investigates the complex connections between the ecological-climatic crises and emerging illnesses, offering an overview on how environmental changes contribute to outbreaks that pose a substantial threat to public health., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2025 The Author(s).

Chronic endometritis (CE) is a persistent inflammatory condition of the endometrium characterized by abnormal infiltration of plasma cells into the endometrial stroma. Frequently associated with repeated implantation failure, recurrent pregnancy loss, and infertility, CE significantly impacts women's health, contributing to conditions such as abnormal uterine bleeding and endometriosis. Treatment typically involves antibiotic therapy; however, the efficacy of these treatments is increasingly compromised by the rise of antimicrobial resistance (AMR). This paper examines the critical links between AMR and CE, proposing strategies to enhance clinical management and optimize treatment outcomes.

Background: Hypercalcemia is a frequently encountered laboratory finding in endocrinology, warranting accurate clinical and laboratory evaluation to identify its cause. While primary hyperparathyroidism and malignancies represent the most common causes, many other etiologies have been described, including some reports of hypercalcemia secondary to adrenal insufficiency. On the contrary, hypoparathyroidism is a relatively common cause of hypocalcemia, often arising as a complication of thyroid surgery. In real-world clinical practice, however, many challenges come into play, and a comprehensive approach may not be enough to establish a diagnosis. Case presentation: we describe a peculiar case of severe hypercalcemia occurring in a 47-year-old woman with a previous history of post-surgical permanent hypoparathyroidism treated with calcitriol (0.5 µg bid) and calcium carbonate (1 g qd), which persisted after withdrawal of these drugs. During her follow-up, an ACTH-independent Cushing syndrome was diagnosed, leading to a unilateral right adrenalectomy. In the two months following surgery, she was admitted to the emergency ward on three occasions because of severe, persistent, idiopathic hypercalcemia. On each occasion, parathyroid hormone levels were confirmed to be undetectable, with low vitamin D levels. Common and rare causes of hypercalcemia were excluded, and the persistence of severely elevated calcium levels led to the empirical use of intravenous clodronate, achieving remission of both hypercalcemia and, unexpectedly, hypoparathyroidism. After 8 months, due to borderline-reduced calcium, calcitriol at 0.5 µg qd was restarted. After 18 months of follow-up, the patient is well and normocalcemic, with low-dose calcitriol. Notably, the patient had no acute adrenal insufficiency, distinguishing this case from other post-adrenalectomy hypercalcemia reports. Conclusions: the history of hypoparathyroidism makes this case even more unusual, and it encourages careful follow-up of hypoparathyroid patients with Cushing syndrome. Ongoing observation, as well as new research on the physiopathology of cortisol and calcium metabolism, are needed to clarify the pathogenesis of this case.

Congenital Adrenal Hyperplasia (CAH) is a group of autosomal recessive endocrine disorders characterized by alteration in adrenal hormonal secretions. The most common form is caused by CYP21A2 mutations that result in 21-hydroxylase deficiency. Clinical features can vary, from salt-wasting forms, characterized by a lack of mineralocorticoid activity with a risk of perinatal-onset adrenal crises, to "simple-virilizing" forms with sufficient aldosterone secretion, up to milder "non-classical" forms, with a variable grade of hyperandrogenism but no severe hormonal deficiencies. During pregnancy, CAH 46,XX fetuses are exposed to elevated androgen levels, leading to a variable grade of virilization and potential central nervous system effects if untreated. These patients are usually (but not always) assigned female at birth, but some cases may be misdiagnosed and assigned male, potentially inducing fertility, gender identity, and sexual behavior issues in adulthood. In these patients, the benefits and risks of a late gender transition should be carefully evaluated. In this paper, we reviewed the literature concerning the most interesting peculiarities of these conditions.

Background: Type B insulin resistance syndrome is a rare form of diabetes due to the presence of anti-insulin receptor antibodies [1, 2], which causes glycemic decompensation and antidiabetic therapy failure and instead responds to immunosuppressive therapy., Case Report: A 67-year-old patient was admitted to the hospital due to autoimmune hemolytic anemia and glycemic decompensation. We first prescribed subcutaneous basal-bolus insulin and then intravenous insulin without improvement in blood sugar levels (between 300 and 500 mg/dL). Considering the non-response to therapy and the autoimmune diathesis of the patient (hemolytic anemia and mixed connective tissue disease), we suspected an autoimmune etiopathogenesis of glycemic decompensation; we excluded type 1 diabetes mellitus (specific antibodies were negative), and we considered the anti-insulin-antibodies-(-assayed and negative) and anti-insulin receptor antibodies (not assayed due to the lack of a center specialized in this assay in the area). Therefore, we decided to start Rituximab. After 2 weeks from the infusion, the patient improved glycemic compensation, reducing insulin requirement. Further, 2 months after the first infusion, the patient stopped insulin, returning to oral therapy with Metformin. To date, the patient has completed 3 cycles of Rituximab with the benefit of glycemic control (HbA1c 6.7%)., Conclusion: The brilliant response to Rituximab supports the hypothesis of an autoimmune pathogenesis. The anti-insulin receptor antibodies (in the type B insulin resistance syndrome) affect mostly middle-aged adults, especially women, in the context of other autoimmune diseases. Hence, it is necessary to consider the diagnosis of this rare disease in order to perform timely and effective treatment., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Parathyroid carcinoma (PC) is a rare endocrine neoplasm that typically presents with osteopenia/osteoporosis, nephrolithiasis, asthenia, and neuropsychiatric symptoms. We describe the case of a 48-year-old woman, presenting with a large painful hematoma in the cervicomediastinal area. The neck ultrasound (US) demonstrated a solid lesion measuring 40 × 80 × 55 mm, markedly hypoechoic, which extended from the right thyroid lobe to the mediastinum. The blood tests showed elevated serum calcium and parathyroid hormone (PTH) concentrations, consistent with hypercalcemic primary hyperparathyroidism. The patient was rehydrated and treated with furosemide, cholecalciferol, and bisphosphonate, and underwent right lower parathyroidectomy, right hemithyroidectomy, and lymphadenectomy of the right VI cervical level. Histological examination was diagnostic for nonangioinvasive or neuroinvasive PC, and the thyroid lobe was the site of lymphocytic thyroiditis; all removed lymph nodes were benign. The postoperative course was regular. Postoperative neck US showed a hypoechoic left thyroid lobe without evidence of residual neoplasm in the right thyroid bed. Levothyroxine therapy of 50 mcg/day was started because of serum thyrotropin concentrations elevated at 18 mcIU/mL (normal reference range, 0.35-4.0 mIU/mL). Eight years after diagnosis, the patient is in good general condition, with no clinical, biochemical, or imaging evidence of disease persistence/recurrence., (© The Author(s) 2024.

Aim: To evaluate predisposition to eating disorders (ED) or body dissatisfaction in adults with type 1 diabetes mellitus (T1DM); to further investigate any differences in ED predisposition between subjects with T1DM on multiple daily injections (MDI) or insulin pumps (CSII) and in respect to control healthy subjects., Methods: We conducted a monocentric, cross-sectional, observational study. We enrolled subjects with T1DM, aged ≥ 18 years, and healthy subjects (HS) as control group. All participants completed two questionnaires to detect possible predisposition to ED: 34-items Body Shape Questionnaire (BSQ) and Eating Disorder Inventory-3 (EDI-3). HS only filled BSQ. For subjects with T1DM data about glycated hemoglobin and duration of disease were also collected., Results: 162 subjects with T1DM (age 41 ± 12 years, 77 [47%] males) and 50 HS (age 38 ± 13 years, 18 (36%) males) were enrolled. 87 subjects with T1DM (54%) were on MDI and 75 (46%) were on CSII. No significant difference in the distribution of BSQ scores between subjects with T1DM and HS was observed (p = 0.551), although 16% of subjects with T1DM scored BSQ class 1 points while 8% of HS scored a BSQ class 1 points. No significant difference in BSQ scores was observed between subjects with T1DM on MDI or CSII. Between these two groups, no differences in EDI-3 scores were observed except for perfectionism score: subjects on MDI present more frequently a predisposition for perfectionism (p < 0.05) and, at a trend level, for bulimia., Conclusion: A non -significant higher percentage of BSQ class 1 was detected in subjects T1DM compared to healthy controls. Among subjects with T1DM, no differences between MDI and CSII were observed in ED predisposition. A more perfectionist personality has been detected among subjects on MDI., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023.

The medical therapy of advanced renal cell carcinoma (RCC) is based on the use of targeted therapies, such as tyrosine kinase inhibitors (TKI) and immune-checkpoint inhibitors (ICI). These therapies are characterized by multiple endocrine adverse events, but the effect on the bone is still less known. Relatively few case reports or small case series have been specifically focused on TKI and ICI effects on bone metabolism. However, the importance to consider these possible side effects is easily intuitable because the bone is one of the most frequent metastatic sites of RCC. Among TKI used in RCC, sunitinib and sorafenib can cause hypophosphatemia with increased PTH levels and low-normal serum calcium levels. Considering ICI, nivolumab and ipilimumab, which can be used in association in a combination strategy, are associated with an increased risk of hypocalcemia, mediated by an autoimmune mechanism targeted on the calcium-sensing receptor. A fearsome complication, reported for TKI and rarely for ICI, is osteonecrosis of the jaw. Awareness of these possible side effects makes a clinical evaluation of RCC patients on anticancer therapy mandatory, especially if associated with antiresorptive therapy such as bisphosphonates and denosumab, which can further increase the risk of these complications.

Background: Medullary thyroid cancer (MTC) is a neuroendocrine tumor arising from parafollicular C-cells of the thyroid gland that, in rare cases, can cause a paraneoplastic ectopic Cushing's syndrome (ECS). The development of Cushing's syndrome (CS) in MTC patients is generally associated with advanced disease and poor prognosis. Summary: We described a case of severe CS due to MTC in a young male. We performed a systematic review to identify cases of ECS due to MTC. We searched PubMed, Scopus, and Web of Science for publications between database inception and February 2022 and we collected the patient characteristics, disease presentation, employed treatment strategies, and disease outcomes. In addition to our patient, we identified 96 cases of ECS due to MTC reported in literature. Mean age at diagnosis was 44.4 years (range 10-84), and there was a male predominance (male:female [M:F] = 1.8:1). Most patients (51%) presented with metastatic disease at diagnosis and showed severe hypercortisolism. Seventeen patients developed distant metastasis and hypercortisolism during follow-up. Interestingly, in 48% of patients, the diagnosis of CS followed the diagnosis of MTC with a median time of 48 months but, among patients in whom the diagnosis was concomitant (38%), symptoms due to hypercortisolism were frequently the reason for seeking medical advice. Pathology results showed evidence of adrenocorticotropic hormone (ACTH) or corticotropin releasing hormone (CRH) positive cells in 76% of patients in whom they were tested. The management of hypercortisolism was challenging in most patients with 48% requiring, eventually, definitive treatment with bilateral adrenalectomy (BLA). Recently, some limited evidence has emerged regarding tyrosine kinase inhibitors (TKIs) treatment for hypercortisolism in patients with ECS due to MTC. Despite limited information on survival, prognosis was generally poor and the main causes of death were either complications of CS or disease progression. Conclusions: Despite its rarity, MTC should be considered in the differential diagnosis of ECS. Management of hypercortisolism is a key factor to improve the patient's symptoms but it is often challenging and BLA is frequently required. Further studies are needed for investigating the role of TKIs in patients with MTC with ECS.

Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive diseases that may cause cortisol insufficiency together with other hormonal alterations. The most common form is 21-hydroxylase deficiency, in which the lack of pituitary negative feedback causes an increase in ACTH and adrenal androgens. Classical forms of CAHs can lead to severe adrenal failure and female virilization. To date, the appropriate management of pregnant CAH patients is still debated regarding appropriate maternal therapy modifications during pregnancy and the risks and benefits of prenatal treatment of the fetus. We conducted a literature search of relevant papers to collect current evidence and experiences on the topic. The most recent and significant articles were selected, and current international guidelines were consulted to update current recommendations and guide clinical practice. Given the lack of randomized clinical trials and other high-quality scientific evidence, the issue is still debated, and great heterogeneity exists in current practice in terms of risk/benefit evaluation and pharmacological choices for pregnancy and prenatal treatment. Glucocorticoid therapy is advised not only in classical CAH patients but also in non-classical, milder forms. The choice of which glucocorticoid to use, and the safety and benefits of dexamethasone therapy aimed at preventing genital virilization are still debated issues. Several advances, however, have been made, especially in terms of fertility and reproduction. This review aims to present the most recent scientific and real-world updates on pregnancy and prenatal management of CAH, with the presentation of various clinical scenarios and specific case-by-case recommendations.

Parathyroid carcinoma (PC) is an extremely rare disease. Although it may occasionally occur in genetic syndromes, it is more often sporadic. It is usually associated with a consistent secretion of PTH, causing severe hypercalcemia and potentially all clinical conditions due to primary hyperparathyroidism. Management of PC can be challenging: some clinical, biochemical, and radiological features may be useful, but the final diagnosis of malignancy strictly relies on histological criteria. To date, radical surgery is the first-choice treatment and is the only effective therapy to control hypercalcemia and other clinical manifestations. On the other hand, chemo- or radiotherapy, local treatments, or novel drugs should be reserved for selected cases. We report an exceptionally unusual case of life-threatening PC, associated with several systemic manifestations: moderate pancreatitis, portal thrombosis, kidney stones, brown tumors, osteoporosis, hungry bone syndrome (HBS), chondrocalcinosis, neuropathy, and depression. The clinical case also represents an opportunity to provide a review of the recent literature, associated with a complete evaluation of the main diagnostic and therapeutic approaches., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Zelano, Locantore, Rota, Policola, Corsello, Rossi, Rufini, Zagaria, Raffaelli and Pontecorvi.)

Cushing's disease represents 60-70% of all cases of Cushing's syndrome, presenting with a constellation of clinical features associated with sustained hypercortisolism. Molecular alterations in corticotrope cells lead to the formation of ACTH-secreting adenomas, with subsequent excessive production of endogenous glucocorticoids. In the last few years, many authors have contributed to analyzing the etiopathogenesis and pathophysiology of corticotrope adenomas, which still need to be fully clarified. New molecular modifications such as somatic mutations of USP8 and other genes have been identified, and several case series and case reports have been published, highlighting new molecular alterations that need to be explored. To investigate the current knowledge of the genetics of ACTH-secreting adenomas, we performed a bibliographic search of the recent scientific literature to identify all pertinent articles. This review presents the most recent updates on somatic and germline mutations underlying Cushing's disease. The prognostic implications of these mutations, in terms of clinical outcomes and therapeutic scenarios, are still debated. Further research is needed to define the clinical features associated with the different genotypes and potential pharmacological targets.

Context: Significant uncertainty exists about the diagnostic accuracy of ultrasonographic (US) features used to predict the risk of thyroid cancer in the pediatric population. Moreover, there are no specific indications for thyroid nodule evaluation in patients during the transition age., Objective: The meta-analysis aimed to address the following question: which thyroid nodule US features have the highest accuracy in predicting malignancy in the transition age., Methods: We performed a meta-analysis of observational/cohort/diagnostic accuracy studies dealing with thyroid nodule sonography, reporting US features, and using histology as a reference standard for the diagnosis of malignancy and histology or cytology for the diagnosis of benignity in the transition age (mean/median age 12-21 years)., Results: The inclusion criteria were met by 14 studies, published between 2005 and 2020, including 1306 thyroid nodules (mean size 17.9 mm) from 1168 subjects. The frequency of thyroid cancer was 36.6%. The US features with the highest diagnostic odds ratio (DOR) for malignancy were the presence of suspicious lymph nodes (DOR: 56.0 (95% CI: 26.0-119.0)), a 'taller than wide' shape of the nodule (6.0 (95% CI: 2.0-16.0)), the presence of microcalcifications (13.0 (95% CI: 6.0-29.0)) and irregular margins (9.0 (95% CI: 5.0-17.0)). Heterogeneity among the studies was substantial., Conclusions: Following the diagnosis of a thyroid nodule in the transition age, a thorough US examination of the neck is warranted. The detection of suspicious lymph nodes and/or thyroid nodules with a 'taller than wide' shape, microcalcifications, and irregular margins is associated with the highest risk of malignancy in the selection of nodules candidates for biopsy.

It is unequivocally recognized that thyroid nodules are frequently detected in the adult population and mostly characterized by benign lesions (up to 70% of them), with only 5%-15% malignant lesions. The evaluation of thyroid lesions with fine-needle aspiration cytology (FNAC) represents one of the first and most useful diagnostic tools in the definition of their nature. Despite the fact that the majority of thyroid lesions are correctly diagnosed as either benign (70%-75%) or malignant (5%-10%) entities, the remaining nodules (20%-25%) represent the "gray zone" of follicular lesions, which belong to indeterminate categories, according to the different classification systems. This indeterminate group of lesions includes both benign and malignant entities, which cannot be easily discriminate with morphology alone. In these last decades, the increasing role of molecular testings, feasibly performed on cytological material combined with the discoveries of specific genetic alterations in the field of thyroid pathology, has opened the pace to their more accurate and specific contribution on cytology. In fact, in 2015, in the revised management guidelines for patients with thyroid nodules and well-differentiated thyroid cancers (WDTCs), the American Thyroid Association (ATA) confirmed the performance of molecular testing in thyroid indeterminate cytology, and the same performance was addressed in recent update of the management of thyroid nodules in the second edition of the Bethesda system for reporting thyroid cytopathology (TBSRTC). In the current review, we discuss the role of molecular tests for the different thyroid diagnostic categories of the Bethesda system for reporting thyroid cytopathology, mostly focusing our attention on the follicular and indeterminate lesions., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Rossi, Locantore, Bruno, Dell’Aquila, Tralongo, Curatolo, Revelli, Raffaelli, Larocca, Pantanowitz and Pontecorvi.)
