ocker. In cases of cardiogenic shock, the administration of beta-blocker should be carried out only after the restoration of satisfactory blood pressure levels- with the prudent use of synthetic catecholamines, if necessary.
Insulinomatosis is a rare cause of hyperinsulinaemic hypoglycaemia. The ideal management approach is not known. A 40-year-old woman with recurrent symptomatic hyperinsulinaemic hypoglycaemia was diagnosed with an insulinoma. A benign 12 mm pancreatic head insulinoma was resected but hypoglycaemia recurred 7 years later. A benign 10 mm pancreatic head insulinoma was then resected but hypoglycaemia recurred within 2 months. Octreotide injections were trialled but exacerbated hypoglycaemia. After a 2-year interval, she underwent total pancreatectomy. A benign 28 mm pancreatic head insulinoma was found alongside insulin-expressing monohormonal endocrine cell clusters (IMECCs) and islet cell hyperplasia, consistent with a diagnosis of insulinomatosis. Hypoglycaemia recurred within 6 weeks. There was no identifiable lesion on MRI pancreas, Ga-68 PET or FDG PET. Diazoxide and everolimus were not tolerated. MEN-1 testing was negative. Insulinomatosis should be suspected in insulinomas with early recurrence or multing monohormonal endocrine cell clusters (IMECCs) and tumour staining only for insulin, whereas MEN-1 associated insulinomas stain for multiple hormones. The ideal treatment strategy is unknown. Total pancreatectomy may not offer cure.
Autoimmune polyglandular syndrome type 1 (APS-1) is a very rare autoimmune entity, accounting for about 400 cases reported worldwide. It is characterized by the presence of at least two of three cardinal components chronic mucocutaneous candidiasis (CMC), hypoparathyroidism and Addison's disease. It typically manifests in childhood with CMC and years later with hypoparathyroidism. A 50-year-old man was referred to the Endocrinology outpatient clinic due to irregular follow-up of primary hypoparathyroidism diagnosed at age 7. Previous analysis reported frequent fluctuations of calcium and phosphate levels and persistent hypercalciuria. He presented several comorbidities, including bilateral cataracts, other ocular disorders, transient alopecia and chronic gastritis. Due to weight loss, fatigue, gastrointestinal complaints and the findings at objective examination, Addison's disease and CMC were investigated and confirmed. Antifungal therapy and hormonal replacement were started with evident clinical improvem clinically relevant, as endocrine and non-endocrine manifestations may occur during its natural history. APS-1 should be considered in cases of acquired hypoparathyroidism, and even more so with manifestations with early onset, family history and consanguinity. APS-1 diagnosis needs a high index of suspicion. Key information such as all the comorbidities and family aspects would never be valued in the absence of a complete clinical history taking. Especially in hypoparathyroidism and Addison's disease in combination, the management of APS-1 can be complex and is not a matter of simply approaching individually each condition. Regular long-term monitoring of APS-1 is essential. Intercalary contact by phone calls benefits the control of the disease and the management of complications.
SOX5 plays an important role in chondrogenesis and chondrocyte differentiation. SOX5 defects in humans (often deletions) result in a Lamb-Shaffer syndrome (LSS), presenting with speech delay, behavioral problems and minor dysmorphic features. We present a patient with idiopathic short stature (ISS) who carried a heterozygous novel variant in SOX5. The patient had no dysmorphic features, but a skeletal survey revealed minor skeletal abnormalities. Laboratory and endocrine evaluation for known causes of growth disorders was negative. The missense variant in SOX5 gene (c.1783A>G, p.K595E) was de novo and was predicted to be deleterious by in silico programs. In summary, we present a patient whose presentation may provide evidence that gene defects in SOX5 may contribute to the etiology of short stature and/or mild skeletal defects beyond LSS.
We report a girl with idiopathic short stature and mild skeletal defects presenting with a de novo variant in SOX5 gene, predicted in silico to be deleterious. Although SOX5 has not been previously specifically associated with short stature, several evidences support its contributing effect on dyschondrogenesis. Missense variants in SOX5 gene may lead to mild phenotypes, differing from typical presentation of patients with Lamb-Shaffer syndrome.

Recent research has highlighted E4BP4 as a novel regulator of metabolisms in various tissues. In this review, we focus on the function and mechanisms of hepatic E4BP4 in regulating lipid and glucose homeostasis, bile metabolism, as well as xenobiotic metabolism. Finally, E4BP4-specific targets will be discussed for the prevention and treatment of metabolic disorders.Previous studies have focused on the role of norepinephrine on arrhythmias, generalized anxiety disorder, and cancer. This study aimed to investigate the effect of norepinephrine on endometrial decidualization. bpV cost Artificial decidualization and norepinephrine-treated mice were established in vivo. In vitro, human endometrial stromal cells were treated with MPA and cAMP to induce decidualization. Decidual markers and important signaling molecules during decidualization were detected using quantitative real-time PCR and Western blot. RNA sequencing was performed to determine related signaling pathways. Exposure to excess norepinephrine significantly restricted the induced expression of decidualized markers Dtprp, BMP2, WNT4, and Hand2 in mice. In vitro, 10 µM norepinephrine markedly downregulated the expressions of prolactin, IGFBP1, and PLZF, which are the specifical markers of decidual stromal cells during decidualization. The gene set enrichment analysis showed a significant enrichment in neuroactive ligand-receptor interactions of norepinephrine treatment group.
