Survival Following Extreme Hypernatraemia Associated with Severe Dehydration and Undiagnosed Diabetes Mellitus.

Case Rep Endocrinol 2019 12;2019:4174259. Epub 2019 Dec 12.

Department of Intensive Care, Western Health, Melbourne, VIC, Australia.

We report a case of a previously well 58-year-old man, who presented with delirium and low GCS, and was found to have extreme hypernatraemia (Na = 191 mmol/L) and hyperglycaemia (glucose = 31 mmol/L). This resulted in a corrected serum sodium of 202 mmol/L. He was treated with fluid and electrolyte replacement in the intensive care unit, and had returned to essentially normal function by hospital discharge. Read More

Rhabdomyolysis in a Young Patient due to Hypothyroidism without Any Precipitating Factor.

Case Rep Endocrinol 2019 3;2019:4210431. Epub 2019 Dec 3.

Hospitalist, Internal Medicine, Staten Island University Hospital, Northwell Health, Staten Island, NY, USA.

Hypothyroidism is characterized by decreased hormone production, which results in various clinical manifestations in different organ systems. Muscular symptoms are common in patents with clinical hypothyroidism which includes muscle cramps, myalgia, and mild to moderate elevation of creatinine kinase less than five times the upper limit of normal. However, rhabdomyolysis due to hypothyroidism is rare and in most of the reported cases a precipitating factor has been found. Read More

Transient Central Diabetes Insipidus after Discontinuation of Vasopressin.

Case Rep Endocrinol 2019 11;2019:4189525. Epub 2019 Dec 11.

Department of Medicine, Brooke Army Medical Center, Fort Sam Houston, TX, USA.

Central diabetes insipidus (CDI) is an uncommon condition resulting from lack of vasopressin secretion from the posterior pituitary gland typically caused by some form of destruction of the gland. Here we present a case of transient CDI after discontinuation of vasopressin used for septic shock without evidence of overt pituitary damage. Serum sodium concentration peaked at 160 mmol/L in the setting of polyuria within days of vasopressin discontinuation without identified alternative etiologies. Read More

Antibody-Mediated Extreme Insulin Resistance: The Importance of Pre-Treatment Screening.

Case Rep Endocrinol 2019 16;2019:8562546. Epub 2019 Nov 16.

Division of Endocrinology, David Geffen School of Medicine, University of California Los Angeles, Los Angeles, CA, USA.

We report the case of a 56 year-old Hispanic male with a 10-year history of type 2 diabetes who presented with abrupt onset of hyperglycemia resistant to escalating doses of intravenous insulin infusion (>2500 units daily). He was diagnosed with antibody-mediated insulin resistance given the presence of hyperglycemia despite receiving >200 units insulin/day, a lack of identifiable precipitants for diabetic ketoacidosis or hyperosmolar hyperglycemic state, and elevated insulin antibodies. He underwent pre-immunomodulatory therapy screening for infections, rheumatologic disorders, and malignancy, which uncovered a new diagnosis of latent tuberculosis. Read More

Hypercalcemic Crisis in a Patient with Post-Surgical Hypoparathyroidism.

Case Rep Endocrinol 2019 12;2019:3503651. Epub 2019 Nov 12.

Department of Medicine, Faculty of Medicine, Chulalongkorn University, Bangkok, Thailand.

Calcium alkali syndrome (CAS), a relatively unusual etiology of hypercalcemia, is characterized by a classical triad of hypercalcemia, azotemia, and metabolic alkalosis. This condition has been described in patients who have taken an excess dose of calcium with an alkali or with a volume-depletion status. To diagnose CAS it requires a high index of suspicion and a detailed history of medication/supplement intake specifically for calcium-containing drugs and a history of all possible ingested alkali.

Hyperandrogenism, Elevated 17-Hydroxyprogesterone and Its Urinary Metabolites in a Young Woman with Ovarian Steroid Cell Tumor, Not Otherwise Specified: Case Report and Review of the Literature.

Case Rep Endocrinol 2019 27;2019:9237459. Epub 2019 Oct 27.

Department of Chemical Pathology, Prince of Wales Hospital, The Chinese University of Hong Kong, Shatin, Hong Kong.

We describe a case of a 24-year-old overweight woman who presented with hirsutism, secondary amenorrhea, clitoromegaly, and symptoms of diabetes mellitus (DM). While a diagnosis of polycystic ovary syndrome (PCOS) with its associated metabolic disturbances was initially considered, serum total testosterone, androstenedione, and 17-hydroxyprogesterone (17-OHP) measured by liquid chromatography tandem mass spectrometry (LC-MS/MS) were significantly increased. As 17-OHP did not increase upon ACTH (Synacthen) stimulation and the urinary steroid profile (USP) was compatible with an ovarian source of 17-OHP excess rather than adrenal, non classical congenital adrenal hyperplasia (NCCAH) was unlikely and an androgen-secreting tumor was suspected.

The Utility of Immunohistochemistry in Differentiating Metastatic Primary Squamous Cell Carcinoma of the Thyroid from a Primary Lung Squamous Cell Carcinoma.

Case Rep Endocrinol 2019 17;2019:8641267. Epub 2019 Oct 17.

Department of General Surgery, Changi General Hospital, 2 Simei Street 3, Singapore 529889.

Primary squamous cell carcinoma of the thyroid gland (PSCCTh) and anaplastic thyroid carcinoma with extensive squamous differentiation are rare entities which pose a diagnostic challenge in determining the primary site when presented as metastases. The difficulty in confirming a thyroid primary is further compounded by the aggressive nature of these tumours which frequently present at advanced stages. We present a case in which the patient presented with a thyroid mass and a lung mass simultaneously. Read More

Immune checkpoint inhibitors, such as anti-programmed cell death-1 (anti-PD-1), have been widely used in the treatment of malignancies. However, these drugs can cause immune-related adverse events resembling autoimmune diseases. There are some reports of Graves' disease (GD) induced by anti-cytotoxic T-lymphocyte-associated antigen 4 antibodies, but reports which discussed GD induced by anti-PD-1 antibodies are very rare.

A Unique Case of IGF-2 Induced Hypoglycemia Associated with Hepatocellular Carcinoma.

Case Rep Endocrinol 2019 13;2019:4601484. Epub 2019 Oct 13.

Department of Gastroenterology and Liver Diseases, Los Angeles County Hospital/University of Southern California, USA.

Tumor-induced hypoglycemia (TIH) associated with hepatocellular carcinoma (HCC) results from tumor production of insulin-like growth factor 2 (IGF-2), resulting in recurrent hypoglycemia. Serum levels of insulin-like growth factor 1 (IGF-1), insulin-like growth factor 2 (IGF-2), or pro-insulin-like growth factor 2 (pro-IGF-2) are required for the diagnosis. However, due to the limited availability of testing in many laboratories, this condition is often overlooked. Read More
