Primary aldosteronism and hypokalemia-induced rhabdomyolysis in a patient with aldosterone-producing adenoma: A case report and literature review.

Many cases of primary aldosteronism (PA) in patients who developed hypokalemia-induced rhabdomyolysis and underwent adrenalectomy for aldosterone-producing adenoma (APA) have been reported; however, the immunohistopathological and molecular features remain unknown. We herein report the case of a 28-year-old woman with PA who presented with hypokalemia-induced rhabdomyolysis and underwent adrenalectomy for unilateral APA. An immunohistochemical analysis revealed that most adenoma cells were positive for steroidogenic enzymes, including CYP11B2.

An 81-Year-Old Man Presenting with Asthenia and Anorexia After an Alcohol-Induced Hypoglycemic Coma and a Diagnosis of Central Adrenal Insufficiency: A Case Report.

BACKGROUND Alcohol abuse inhibits the ability of the liver to release glucose into the bloodstream, primarily by inhibiting gluconeogenesis, so chronic alcohol abusers exhibit hypoglycemia after drinking alcohol without eating; this is called alcohol-induced hypoglycemia. Central adrenal insufficiency (AI) is characterized by cortisol deficiency due to a lack of adrenocorticotropic hormone. It is challenging to diagnose central AI, as it usually presents with nonspecific symptoms, such as asthenia, anorexia, and a tendency toward hypoglycemia.

A 75-Year-Old Woman with a 5-Year History of Controlled Type 2 Diabetes Mellitus Presenting with Polydipsia and Polyuria and a Diagnosis of Central Diabetes Insipidus.

BACKGROUND Central diabetes insipidus (CDI) is a rare disorder characterized by large volumes of dilute urine because of a lack of antidiuretic hormone. Co-existing CDI and diabetes mellitus without inherited disorders such as Wolfram syndrome are rare. It is both important and challenging to diagnose this combination because the 2 conditions present with thirst, polydipsia, and polyuria.

Hypoglycemic Hemiplegia Associated with Reversible Narrowing of the Contralateral Middle Cerebral Artery in a Patient with Adrenal Insufficiency.

A 56-year-old man with a 2.5-month history of anorexia developed sweating, weakness, and left hemiplegia and hemispatial neglect. Brain magnetic resonance imaging detected no abnormalities, but magnetic resonance angiography revealed narrowing of the right middle cerebral artery (MCA).

Primary Aldosteronism Presenting with Hypertension Five Days after Delivery: A Case Report and Literature Review.

A 35-year-old Japanese woman with no history of hypertension developed hypertension 5 days after normal delivery. Endocrinological and radiological examinations indicated primary aldosteronism (PA) and a 1.4-cm left adrenal tumor.

Isolated Adrenocorticotropic Hormone Deficiency Associated with Severe Hyperkalemia During Pembrolizumab Therapy in a Patient with Ureteral Cancer and an Ileal Conduit: A Case Report and Literature Review.

BACKGROUND Immune checkpoint inhibitors (ICIs) are anticancer medications that enhance the antitumor immune response. The clinical benefit afforded by ICIs, however, can be accompanied by immune-related adverse events (IRAEs). One of the common endocrine IRAEs is hypophysitis, which often causes hypopituitarism with secondary adrenal insufficiency (AI).

Central Diabetes Insipidus after Syndrome of Inappropriate Antidiuretic Hormone Secretion with Severe Hyponatremia in a Patient with Rathke's Cleft Cyst.

A 49-year-old man developed severe hyponatremia associated with transient headache and was diagnosed with syndrome of inappropriate antidiuretic hormone secretion (SIADH). Fluid restriction and sodium supplementation corrected the hyponatremia. However, several days later, the patient exhibited hypernatremia with thirst and polyuria.

Prolonged Postoperative Pyrexia and Transient Nonnephrogenic Vasopressin-Analogue-Resistant Polyuria following Endoscopic Transsphenoidal Resection of an Infundibular Epidermoid Cyst.

Prolonged postoperative pyrexia (PPP) due to Mollaret's meningitis following endoscopic transsphenoidal surgery (eTSS) for an intracranial epidermoid cyst can be confused with postoperative meningeal infection after transsphenoidal resection, especially in the middle of the COVID-19 pandemic. Anosmia, as well as dysgeusia, cannot be evaluated in patients of eTSS for a while after surgery. We report a case of an infundibular epidermoid cyst with post-eTSS Mollaret's meningitis (MM).

Isolated Adrenocorticotropic Hormone Deficiency and Primary Hypothyroidism in a Patient Undergoing Long-Term Hemodialysis: A Case Report and Literature Review.

BACKGROUND Patients with end-stage renal disease undergoing long-term maintenance hemodialysis are more likely than the general population to exhibit primary hypothyroidism. Only a few cases of isolated adrenocorticotropic hormone deficiency (IAD) among hemodialysis patients have been reported. We herein report an unusual case of a patient undergoing long-term hemodialysis who exhibited both IAD and primary hypothyroidism.

Isolated Adrenocorticotropic Hormone Deficiency Presenting with Severe Hyponatremia and Rhabdomyolysis: A Case Report and Literature Review.

BACKGROUND Isolated adrenocorticotropic hormone deficiency (IAD) is a rare disorder characterized by central adrenal insufficiency (AI) but normal secretion of pituitary hormones other than adrenocorticotropic hormone. IAD usually presents with unspecific symptoms of AI, such as anorexia and fatigue, but some patients present with a variety of atypical manifestations. Rhabdomyolysis is a potentially life-threatening clinical syndrome caused by skeletal muscle injury with the release of muscle cell contents into the circulation.

Non-insulin-dependent Diabetes Mellitus Induced by Immune Checkpoint Inhibitor Therapy in an Insulinoma-associated Antigen-2 Autoantibody-positive Patient with Advanced Gastric Cancer.

A 70-year-old man with insulinoma-associated antigen-2 autoantibodies developed diabetes mellitus (DM) without ketoacidosis after starting nivolumab to treat advanced gastric cancer. He subsequently exhibited preserved insulin-secretion capacity for over one year. Immune checkpoint inhibitors (ICIs) infrequently cause type 1 DM associated with the rapid loss of insulin secretion and ketoacidosis as an immune-related adverse event.

Isolated adrenocorticotropic hormone deficiency and thyroiditis associated with nivolumab therapy in a patient with advanced lung adenocarcinoma: a case report and review of the literature.

Introduction: Immune checkpoint inhibitors are a promising class of anticancer drugs. The clinical benefits afforded by immune checkpoint inhibitors can be accompanied by immune-related adverse events that affect multiple organs, and endocrine immune-related adverse events include thyroiditis and hypophysitis. Hypophysitis is less frequent and has a less severe clinical presentation in patients treated with other immune checkpoint inhibitors, such as nivolumab, pembrolizumab, and atezolizumab, than in those treated with ipilimumab.

A case of normotensive incidentally discovered adrenal pheochromocytoma.

Pheochromocytomas are catecholamine-producing neuroendocrine tumors that arise from the adrenal medulla. The clinical presentation includes headache, palpitation, and hypertension, but pheochromocytomas are sometimes clinically silent. The present case highlights the importance of biochemical testing for pheochromocytoma in patients with adrenal incidentaloma, even if they are completely normotensive and asymptomatic.

Glutamic Acid Decarboxylase Autoantibody-negative Slowly Progressive Type 1 Diabetes Mellitus: A Case Report and Literature Review.

A 59-year-old non-obese Japanese woman developed diabetes mellitus with a negative glutamic acid decarboxylase autoantibody (GADA) test result. Her hyperglycemia was initially well controlled by oral hypoglycemic agents; however, despite continued treatment the hyperglycemia gradually worsened. As she had endogenous insulin deficiency and tested positive for insulin autoantibody (IAA), insulin therapy was initiated.

Reversible Non-parkinsonian Bradykinesia with Impaired Frontal Lobe Function as the Predominant Manifestation of Adrenal Insufficiency.

A 69-year-old Japanese man with a history of suprasellar surgery and irradiation developed bradykinesia and mild fatigue without muscle weakness, myalgia, pyramidal or extrapyramidal signs, parkinsonian symptoms, or ataxia. An endocrinological work-up revealed anterior hypopituitarism associated with secondary adrenal insufficiency. Higher brain function tests indicated an impaired frontal lobe function.

Isolated Adrenocorticotropin Deficiency due to Nivolumab-induced Hypophysitis in a Patient with Advanced Lung Adenocarcinoma: A Case Report and Literature Review.

A 63-year-old Japanese woman with advanced lung adenocarcinoma developed isolated adrenocorticotropin deficiency caused by immune checkpoint inhibitor (ICI)-related hypophysitis following 8 months of nivolumab therapy. Prompt corticosteroid replacement therapy effectively relieved her secondary adrenal insufficiency symptoms and allowed her to pursue nivolumab therapy, which had been effective for the control of lung adenocarcinoma. Human leukocyte antigen (HLA) typing revealed the presence of the DRB1*04:05-DQA1*03:03-DQB1*04:01 haplotype, which is associated with susceptibility to autoimmune polyglandular syndrome with pituitary disorder in the Japanese population.

Quantitative Relationship Between Cumulative Risk Alleles Based on Genome-Wide Association Studies and Type 2 Diabetes Mellitus: A Systematic Review and Meta-analysis.

Many epidemiological studies have assessed the genetic risk of having undiagnosed or of developing type 2 diabetes mellitus (T2DM) using several single nucleotide polymorphisms (SNPs) based on findings of genome-wide association studies (GWAS). However, the quantitative association of cumulative risk alleles (RAs) of such SNPs with T2DM risk has been unclear. The aim of this meta-analysis is to review the strength of the association between cumulative RAs and T2DM risk.

Acute hypopituitarism associated with periorbital swelling and cardiac dysfunction in a patient with pituitary tumor apoplexy: a case report.

Background: Pituitary tumor apoplexy is a rare clinical syndrome caused by acute hemorrhage or infarction in a preexisting pituitary adenoma. It typically manifests as an acute episode of headache, visual disturbance, mental status changes, cranial nerve palsy, and endocrine pituitary dysfunction. However, not all patients present with classical symptoms, so it is pertinent to appreciate the clinical spectrum of pituitary tumor apoplexy presentation.

Generalized Status Epilepticus in a Patient with Acute-onset Type 1 Diabetes Mellitus Associated with Severe Kidney Dysfunction: A Case Report and Literature Review.

A 65-year-old Japanese man with advanced chronic kidney disease (CKD) developed acute-onset type 1 diabetes mellitus (T1D) that was associated with severe acute kidney injury and was manifested by generalized tonic-clonic status epilepticus. His seizures resolved without recurrence after correcting the diabetic ketoacidosis. Although hyperglycemia is an important cause of acute symptomatic seizure (ASS), patients with ketotic hyperglycemia develop ASS less frequently.

Persistent Graves' hyperthyroidism despite rapid negative conversion of thyroid-stimulating hormone-binding inhibitory immunoglobulin assay results: a case report.

Background: Graves' disease is an autoimmune thyroid disorder characterized by hyperthyroidism, and patients exhibit thyroid-stimulating hormone receptor antibody. The major methods of measuring circulating thyroid-stimulating hormone receptor antibody include the thyroid-stimulating hormone-binding inhibitory immunoglobulin assays. Although the diagnostic accuracy of these assays has been improved, a minority of patients with Graves' disease test negative even on second-generation and third-generation thyroid-stimulating hormone-binding inhibitory immunoglobulins.

Unstable bodyweight and incident type 2 diabetes mellitus: A meta-analysis.

Aims/introduction: The present meta-analysis aimed to clarify the association of unstable bodyweight with the risk of type 2 diabetes mellitus, an association that has been controversial among longitudinal studies.

Materials And Methods: An electronic literature search using EMBASE and MEDLINE was followed up to 31 August 2016. The relative risks (RRs) of type 2 diabetes mellitus in individuals with unstable bodyweight were pooled using the inverse variance method.

Lung adenocarcinoma and adrenocortical carcinoma in a patient with multiple endocrine neoplasia type 1.

Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant disorder caused by heterozygous germline mutations in the tumor suppressor gene , which encodes a nuclear protein, menin. MEN1 is characterized by the combined occurrence of tumors involving the pituitary gland, pancreatic islets, and parathyroid glands. Additionally, patients with MEN1 often exhibit adrenal tumors.

A case of central diabetes insipidus associated with cardiac dysfunction.

Central diabetes insipidus (CDI) results from a deficiency of arginine vasopressin (AVP) secretion. It is treated by replacement therapy with the synthetic AVP analogue desmopressin. To prevent heart failure in patients with CDI accompanied by cardiac dysfunction, controlling sodium and water intake is essential, using the minimum effective dose of desmopressin.

Fibromyalgia in a Patient with Cushing's Disease Accompanied by Central Hypothyroidism.

A 39-year-old woman with a 3-year history of a rounded face developed widespread myalgia. Detailed examinations revealed no disorders that could explain the pain other than concomitant Cushing's disease and central hypothyroidism. Both the hypercortisolemia and hypothyroidism completely resolved after the patient underwent surgery to treat Cushing's disease, but she continued to experience unresolved myalgia and met the diagnostic criteria for fibromyalgia.
