BACKGROUND: Giant pituitary adenomas represent a surgical challenge. We present the results of the endoscopic endonasal approach (EEA) for giant pituitary adenomas. METHODS: We retrospectively reviewed medical records of 55 patients with giant pituitary adenomas (> 4 cm in maximum diameter) that underwent an EEA from 2008 - 2016. Factors affecting the extent of resection (EOR) were evaluated. RESULTS: Mean age was 55.5 years. All tumors were non-functional except in four patients (GH-secreting [2], ACTH-secreting [1], prolactinoma [1])...

The pituitary stalk (PS) is a relatively thin bundle connecting the hypophyseal stalk to the pituitary gland; it consists of both axons of the hypothalamic nuclei (terminating in the neurohypophysis) and the system of portal vessels. Compression of the PS by a space-occupying lesion or its transection (forced or intended) during surgery may lead to the development of endocrine disorders: hypopituitarism, diabetes insipidus, and hyperprolactinemia. The modern literature lacks studies evaluating the severity of endocrine disorders depending on the PS condition before and after surgery...

Keap1 is a negative regulator of Nrf2, a master transcription factor that regulates cytoprotection against oxidative and electrophilic stresses. Although several studies have suggested that the Keap1-Nrf2 system contributes to bone formation besides the maintenance of redox homeostasis, how Nrf2 hyperactivation by Keap1 deficiency affects the bone formation remains to be explored, as the Keap1-null mice are juvenile lethal. To overcome this problem, we used viable Keap1-deficient mice that we have generated by deleting the esophageal Nrf2 in Keap1-null mice (NEKO mice)...

Diagnosis and treatment of Langerhans cell histiocytosis (LCH) in elderly patients are often difficult. We report here a 61-year-old female suffering from a refractory axillary ulcer for nearly a year, whose biopsy revealed LCH. It was also noted that the patient had other cutaneous papulovesicular eruptions of LCH as well as central diabetes insipidus. The patient was first successfully treated with multiagent chemotherapy (cytosine arabinoside/vinblastine/prednisolone). DDAVP also well controlled diabetes insipidus; however, the axillary ulcer and cutaneous LCH relapsed...

Bartter syndrome (BS) type 1 (OMIM #601678) is a hereditary salt-losing renal tubular disorder characterized by hypokalemic metabolic alkalosis, hypercalciuria, nephrocalcinosis, polyuria, recurrent vomiting, and growth retardation. It is caused by loss-of-function mutations of the SLC12A1 gene, encoding the furosemide-sensitive Na-K-Cl cotransporter. Recently, a phenotypic variability has been observed in patients with genetically determined BS, including absence of nephrocalcinosis, hypokalemia, and/or metabolic alkalosis in the first year of life as well as persistent metabolic acidosis mimicking distal renal tubular acidosis...

OBJECTIVES: Removal of recurrent or residual symptomatic craniopharyngiomas is more challenging than the primary surgery. The extended endoscopic endonasal (EEE) approach has been proposed an alternative surgical route for removal of various suprasellar tumors including craniopharyngiomas currently. In this study, we summarized the operative experience and described the feasibility and advantages of this technique in recurrent or residual symptomatic craniopharyngiomas. PATIENTS AND METHODS: A retrospective review of 15 patients (9 males and 6 females) whom underwent EEE approach between April 2012 and February 2017, were included in this study...

Objective: To evaluate the clinical characteristics and etiologies of central diabetes insipidus (CDI). Methods: The clinical data of 230 patients with CDI in the Department of Endocrinology of Chinese PLA General Hospital from 2008 June to 2014 December were collected and analyzed retrospectively. Results: The three most common causes of CDI were idiopathic CDI, lymphocytic hypophysitis and intracranial germ cell tumors. Among all the CDI, the idiopathic CDI accounted for 37.48%. There were significant differences in age onset and gender distribution among the different causes of CDI...

OBJECTIVE: Diabetes insipidus (DI) and primary polydipsia (PP) are characterised by polyuria and polydipsia. It is crucial to differentiate between these two disorders since the treatment is different. The aim of this study was to evaluate the diagnostic value of the short and an extended variant of the water deprivation test (WDT) and of measuring urinary vasopressin (AVP) in patients with polyuria and polydipsia. DESIGN: A retrospective, single-centre study based on WDTs performed between 2004 and 2014 including 104 consecutive patients with the polyuria-polydipsia syndrome...

Immune checkpoint inhibitors are the mainstay of treatment for advanced melanoma, and their use is being increasingly implicated in the development of autoimmune endocrinopathies. We present a case of a 52-year-old man with metastatic melanoma on combination nivolumab and ipilumimab therapy who developed concurrent hypophysitis, type 1 diabetes mellitus (T1DM) and diabetes insipidus. He presented prior to third cycle of combination treatment with a headache, myalgias and fatigue. Biochemistry and MRI pituitary confirmed anterior pituitary dysfunction with a TSH: 0...

Central diabetes insipidus (DI) was detected in a patient with hemorrhagic fever with renal syndrome (HFRS) who had been molecularly and serologically diagnosed with Hantaan virus infection. We recommend that clinicians differentiate central DI in HFRS patients with a persistent diuretic phase even when pituitary MRI findings are normal.

Nephrogenic diabetes insipidus (NDI), a rare cause of polyuria and polydipsia in children, is usually managed with medications and careful monitoring of water intake. We present a child who was incidentally found to have right hydronephrosis secondary to ureteropelvic junction obstruction, and was subsequently also diagnosed with NDI. After being medically managed, he underwent open right pyeloplasty. His polydipsia abated within one month of surgery, and he has done well off of medications since that time...

Background: Keratinous or epidermoid cysts (ECs) are encapsulated lesions lined by squamous cell epithelium. They comprise approximately 1% of intracranial lesions. Contrary to dermoid cysts, they lack dermal elements such as sebaceous or apocrine glands and hair follicles. The sellar region is the second most common intracranial site following the cerebellopontine angle. Here, we report a case of EC in a patient who complained of endocrine disturbances. We also performed a systematic review on previously published cases to analyze clinical and radiological characteristics and report the treatment outcomes of suprasellar ECs...

A variety of neoplastic, inflammatory and congenital conditions can cause pituitary stalk thickening. Differentiating between these causes is important as targeted treatment may be offered. Diagnostic work-up consists of a thorough history, examination, biochemical analysis and imaging. We present the case of a 33-year-old male who presented with diabetes insipidus and had pituitary stalk thickening on magnetic resonance imaging. Further investigations revealed an elevated CSF βhCG, which raised the possibility of an intracranial germ cell tumor...

A 26-year-old woman presented with severe postpartum headaches. Magnetic resonance imaging (MRI) revealed a symmetric, heterogeneous enlargement of the pituitary gland. Three months later, she developed central diabetes insipidus. A diagnosis of postpartum hypophysitis was suspected and corticosteroids were prescribed. Six months later, the pituitary mass showed further enlargement and characteristics of a necrotic abscess with a peripheral shell and infiltration of the hypothalamus. Transsphenoidal surgery was performed, disclosing a pus-filled cavity which was drained...

OBJECTIVES: It is well-known that Rathke's cleft cysts (RCCs) infrequently cause headache, endocrinological dysfunction, and visual disturbance, and in rare cases, cause diabetes insipidus (DI). Although surgical evacuation of the cyst content can result in high rates of symptomatic improvement, not only the treatment efficacy but also the pathophysiology of DI with RCC are undetermined. The aim of this study is to elucidate the underlying mechanisms and outcomes of DI associated with RCCs...
