Hypoglycemia after bariatric surgery: importance of exhaustive hormonal study.

Endocrinol Diabetes Metab Case Rep 2021 Mar 20;2021. Epub 2021 Mar 20.

Endocrinology and Nutrition, Hospital Universitari Germans Trias I Pujol, Badalona, Spain.

Summary: Hypoglycemia is an uncommon clinical problem in non-diabetic patients or patients not being treated for diabetes mellitus. It is a rare, but well-established complication of bariatric surgery and, in some cases, it can be the only symptom of another medical problem. A 50-year-old woman with a history of partially recovered hypopituitarism after transsphenoidal surgery for a non-functioning pituitary macroadenoma complained about symptomatic hypoglycemia after sleeve gastrectomy surgery.

A comparative study of functioning and non-functioning pituitary adenomas.

Medicine (Baltimore) 2021 Apr;100(14):e25306

Department of Ophthalmology, Peking University People's Hospital, Eye Diseases and Optometry Institute, Beijing Key Laboratory of Diagnosis and Therapy of Retinal and Choroid Diseases, College of Optometry, Peking University Health Science Center, Xi Cheng District.

Abstract: Pituitary tumors commonly cause visual impairment and the degree of impairment can depend on the size, location, and type of the tumor. However, no studies have been made regarding the differences caused by functioning pituitary adenoma (FPA) and non-functioning pituitary adenoma (NFPA). We aimed to investigate the relationship between clinical characteristics and visual impairment in patients with FPA and NFPA. Read More

First German Guideline on Diagnostics and Therapy of Clinically Non-Functioning Pituitary Tumors.

Exp Clin Endocrinol Diabetes 2021 Mar 9;129(3):250-264. Epub 2021 Mar 9.

Department of Internal Medicine I, Division of Endocrinology and Diabetes, University Hospital Würzburg, University of Würzburg, Würzburg, Germany.

Although non-functioning pituitary tumors are frequent, diagnostic and therapeutic concepts are not well standardized. We here present the first German multidisciplinary guideline on this topic. The single most important message is to manage the patients by a multidisciplinary team (consisting at least of an endocrinologist, a neurosurgeon, and a (neuro-) radiologist). Read More

MCM7 as a marker of postsurgical progression in non-functioning pituitary adenomas.

Eur J Endocrinol 2021 Apr;184(4):521-531

Department of Medicine, Sahlgrenska University Hospital, Gothenburg, Sweden.

Objective: Current markers predicting tumour progression of pituitary adenomas after surgery are insufficient. Our objective was to investigate if minichromosome maintenance protein 7 (MCM7) expression predicts tumour progression in non-functioning pituitary adenomas (NFPAs).

Methods: In a cohort study of surgically treated NFPAs, two groups with distinctly different behaviour of a residual tumour were selected: one group requiring reintervention due to tumour progression (reintervention group, n = 57) and one with residual tumours without progression (radiologically stable group, n = 40).

Diabetes and Endocrinology, Queen's Medical Centre Nottingham University Hospital NHS Trust, Nottingham, UK.

An 85-year-old man was referred to endocrinology following the discovery of an incidental pituitary mass on cranial imaging which was thought to be a non-functioning adenoma during an admission with headaches, lethargy, confusion and hyponatraemia. He had a history of Hürthle cell carcinoma of the thyroid treated with total thyroidectomy, ablative radioiodine therapy and thyroxine replacement. Subsequently, he developed metastatic spread to the neck, lungs and skeleton. Read More

Leiomyosarcoma of the inferior vena cava posing as an adrenal incidentaloma.

BMJ Case Rep 2021 Jan 18;14(1). Epub 2021 Jan 18.

Pathology, Jawaharlal Institute of Postgraduate Medical Education and Research, Puducherry, India.

Adrenal incidentalomas are incidentally detected adrenal lesions on imaging, which have a variety of differential diagnoses, the most common being a non-functioning adenoma. Surgical intervention for these lesions is needed when there is hypersecretion, for lesions larger than 4 cm and smaller lesions with suspicious characteristics. Here we present a young woman who was incidentally found to have a right suprarenal mass with loss of fat planes with the inferior vena cava (IVC). Read More

Therapeutic approach to non-functioning pituitary adenomas.

Med Clin (Barc) 2021 03 14;156(6):284-289. Epub 2021 Jan 14.

Servicio de Neurocirugía. Hospital Universitario La Paz, Madrid, España.

The treatment of non-functioning pituitary adenomas raises two questions: when should they be treated and what role does each available treatment play. We review the usefulness of the different treatments and propose a therapeutic scheme based on the existing literature. Active treatment of pituitary adenomas should be performed when they produce symptoms, have contact with the optic tract, or have grown on imaging tests. Read More

Metastatic insulinoma presenting 14 years after benign tumour resection: a rare case and management dilemma.

Endocrinol Diabetes Metab Case Rep 2020 Sep 23;2020. Epub 2020 Sep 23.

Department of Diabetes and Endocrinology, Royal Glamorgan Hospital, Llantrisant, UK.

Summary: We present a 60-year-old woman who underwent successful surgical resection (partial pancreatectomy) for a low grade non-functioning pancreatic neuroendocrine tumour (pNET), with no biochemical or radiological features of recurrence on follow-up visits for 5 years. Fourteen years after the initial surgery, she developed spontaneous severe hypoglycaemic episodes which required hospitalisation, with subsequent investigations confirming the diagnosis of a metastatic insulin-secreting pNET (insulinoma). Medical management of her severe spontaneous hypoglycaemic episodes remained challenging, despite optimum use of diazoxide and somatostatin analogue therapy. Read More
