This systematic review summarizes the existing data on headache and pregnancy with a scope on clinical headache phenotypes, treatment of headaches in pregnancy and effects of headache medications on the child during pregnancy and breastfeeding, headache related complications, and diagnostics of headache in pregnancy. Headache during pregnancy can be both primary and secondary, and in the last case can be a symptom of a life-threatening condition. The most common secondary headaches are stroke, cerebral venous thrombosis, subarachnoid hemorrhage, pituitary tumor, choriocarcinoma, eclampsia, preeclampsia, idiopathic intracranial hypertension, and reversible cerebral vasoconstriction syndrome...

Pituicytomas are rare low-grade glial lesions of neurohypophysis or adenohypophysis. They are often misdiagnosed as adenomas due to their similar morphology. Previous reports have underlined their non specific aspect. In our experience, presence of flow voids on MR, which usually indicate hypervascularized tumors with strong arterial supply, may be a useful sign to identify pituicytomas. Unlike adenomas, pituicytomas are highly vascularized tumors. Second, we emphasize the strong enhancement of these tumors when compared to normal hypophysis, which may be another sign of the their hypervascularization...

Pituitary gonadotropes synthesize and secrete follicle-stimulating hormone (FSH). FSH is a heterodimer that consists of an α-and a β-subunit. The α - subunit is common to other pituitary and placental glycoprotein hormones and the β-subunit is the hormone/receptor specific subunit. Although the pituitary is the main tissue that accounts for circulating hormone, previous and recent reports indicate extra-pituitary sources of FSH production including mouse gonads, human stomach, prostate, umbilical cord vein endothelial cells, uterine myometrium, placenta and chicken abdominal adipose tissue...

Immune checkpoint inhibitors have improved survival in numerous advanced malignancies, but are associated with a number of immune-related adverse events, including endocrinopathies. Endogenous Cushing's syndrome (CS) is a rare disorder resulting from exposure to high levels of circulating cortisol. CS can be caused either by adrenal cortex tumors or hyperplasia or by pituitary or extra-pituitary tumors over-secreting ACTH (known as ACTH-dependent CS). We report the first case of transient ACTH-dependent CS, which appeared after combined ipilimumab and nivolumab therapy...

PURPOSE: Silent corticotroph adenomas (SCAs) are clinically silent and non-secreting, but exhibit positive adrenocorticotropic hormone (ACTH) immunostaining. We characterized a single center cohort of SCA patients, compared the SCAs to silent gonadotroph adenomas (SGAs), identified predictors of recurrence, and reviewed and compared the cohort to previously published SCAs cases. METHODS: Retrospective review of SCA and SGA surgically resected patients over 10 years and 6 years, respectively...

The two types of TGF-β receptors play a crucial role in TGF-β signaling. It has been reported that TGF-β signaling activity may be associated with the development and invasion of NFPAs. However, the role of TGF-β receptor signaling in NFPAs has not been fully explored. In this study, the expression of TGF-β RI and TGF-β RII in normal anterior pituitaries, invasive NFPAs and non-invasive NFPAs was analyzed by qRT-PCR, western blot, and immunohistochemistry. We found that TGF-β RII protein and mRNA levels gradually decreased from normal anterior pituitaries, noninvasive NFPAs to invasive NFPAs...

OBJECTIVE Accurate presurgical localization of microadenomas in Cushing's disease (CD) leads to improved remission rates and decreased adverse events. Volumetric gradient recalled echo (3D-GRE) MRI detects pituitary microadenomas in CD in up to 50%-80% cases as a focus of hypointensity due to delayed contrast wash-in. The authors have previously reported that postcontrast FLAIR imaging may be useful in detecting otherwise MRI-negative pituitary microadenomas as foci of hyperintensity. This reflects theoretically complementary imaging of microadenomas due to delayed contrast washout...

OBJECTIVE Cushing disease is caused by a pituitary micro- or macroadenoma that hypersecretes adrenocorticotropic hormone (ACTH), resulting in hypercortisolemia. For decades, transsphenoidal resection (TSR) has been an efficacious treatment but with certain limitations, namely precise tumor localization and complete excision. The authors evaluated the novel use of a double-antibody sandwich assay for the real-time quantitation of ACTH in resected pituitary specimens with the goals of augmenting pathological diagnosis and ultimately improving long-term patient outcome...

Acromegaly is a rare and severe condition, presenting with typical signs and symptoms. The diagnosis is often initially made years after the first manifestations of the disease. In more than 99% of patients the disease is caused by a benign pituitary tumor that secretes growth hormone (GH). The diagnosis is based on the presence of increased insulin-like growth factor 1 (IGF-1) levels and a lack of GH suppression in the oral glucose tolerance test. The standard imaging procedure for tumor detection is magnetic resonance imaging in the region of the sella turcica...

Adipsic hypernatremia is a rare disease presenting as persistent hypernatremia with disturbance of thirst regulation and hypothalamic dysfunction. As a result of congenital disease, tumors, or inflammation, most cases are accompanied by structural abnormalities in the hypothalamic-pituitary area. While cases with no hypothalamic-pituitary structural lesion have been reported, their etiology has not been elucidated. Recently, we reported three patients with adipsic hypernatremia whose serum-derived immunoglobulin (Ig) specifically reacted with mouse subfornical organ (SFO) tissue...

BackgroundThe majority of pituitary adenomas are sporadic, but about 5% of them occur in a familial setting, predominantly in multiple endocrine neoplasia type 1 and Carney complex. Familial isolated pituitary adenomas (FIPA), unrelated to the syndromes mentioned above, were also described. The clinical course of FIPA differs significantly from sporadic cases, and is characterized by a larger tumor size, more aggressive course and younger patients' age at the moment of recognition. ObjectivesThe aim of this retrospective study is to present 4 families in which two closely related people were diagnosed with pituitary adenomas...

Microtubules are multifunctional cytoskeletal proteins that are involved in crucial cellular roles including maintenance of cell shape, intracellular transport, meiosis, and mitosis. Class III beta-tubulin (βIII-tubulin, also known as TUBB3) is a microtubule protein, normally expressed in cells of neuronal origin. Its expression was also reported in various other tumor types, such as several types of lung cancer, ovarian cancer, and esophageal cancer. TUBB3 is of clinical relevance as overexpression has been linked to poor response to microtubule-targeting anti-cancer drugs such as taxanes...

Endocan expression has been reported to be associated with aggressive tumor progression and poor outcomes in various cancers, such as breast cancer, renal cell cancer, lung cancer, gastric cancer, and pituitary adenomas. However, the prognostic significance of endocan in neuroendocrine tumors remains unknown. Thus, the aim of this study was to determine the correlation between endocan expression in pancreatic neuroendocrine tumor (PNET) tissues and progression-free survival. This study included 73 patients with confirmed PNETs who were treated in a single tertiary center in north Taiwan between 1992 and 2015...

OBJECTIVE: The outcomes of recent endoscopic surgery of nonfunctioning pituitary adenomas (NFPAs) were controversial when compared to traditional microscopic surgery. We aimed to assess the outcomes of endoscopic transsphenoidal surgeries performed by one surgeon with 7 years of experience and elucidate the predictive factors for surgical outcomes for NFPAs. METHODS: We included 331 patients (155 men, 176 women) with clinical NFPAs who underwent transsphenoidal surgery due to visual symptoms by a single surgeon in Seoul National University Hospital from March 2010 to May 2016...

BACKGROUND: The excellent visualization and minimally invasive approach employed in endoscopic endonasal procedures has now revolutionized the pituitary surgery, replacing the transnasal microscopic technique worldwide. However, it involves major shift in hand-eye co-ordination from static 3 dimensional images of microscope to 2 dimensional endoscopic images hence demands training and inter-disciplinary approach. Here we present our experiences in learning and developing a safe endonasal transsphenoidal endoscopic approach to resect pituitary adenomas...
