Interleukin-1 receptor associated kinase 4 (IRAK4) plays a critical role in innate immune signaling by Toll-like receptors (TLRs), and loss of IRAK4 activity in mice and humans increases susceptibility to bacterial infections and causes defects in TLR and IL1 ligand sensing. However, the mechanism by which IRAK4 activity regulates the production of downstream inflammatory cytokines is unclear. Using transcriptomic and biochemical analyses of human monocytes treated with a highly potent and selective inhibitor of IRAK4, we show that IRAK4 kinase activity controls the activation of the transcription factor IRF5, a transcription factor implicated in the pathogenesis of multiple autoimmune diseases...

PURPOSE: The primary cause of Cushing's disease is adrenocorticotropic hormone (ACTH)-producing pituitary adenomas. EGFR signaling induces POMC mRNA-transcript levels and ACTH secretion from corticotroph tumors. The Jak-STAT pathway is located downstream of EGFR signaling; therefore, a Jak2 inhibitor could be an effective therapy for EGFR-related tumors. In this study, we determined the effect of a potent and selective Jak2 inhibitor, SD1029, on ACTH production and proliferation in mouse AtT20 corticotroph tumor cells...

Silent corticotroph staining pituitary adenoma (SCA) represents an uncommon subset of Non-Functioning adenomas (NFAs), hypothesized to be more locally aggressive. In this retrospective multicenter study, we investigate the safety and effectiveness of Stereotactic Radiosurgery (SRS) in patients with SCA compared with other non-SCA NFA's. Eight centers participating in the International Gamma-Knife Research Foundation (IGKRF) contributed to this study. Outcomes of 50 patients with confirmed SCAs and 307 patients with confirmed non-SCA NFA's treated with SRS were evaluated...

PURPOSE: Transsphenoidal surgery(TSS) is the primary treatment modality for Cushing's disease(CD). However, the predictors of post-operative remission and recurrence remain debatable. Thus, we studied the post-operative remission and long term recurrence rates, as well as their respective predictive factors. METHODS: Retrospective analysis of case records of 230 CDpatients who underwent primary microscopic TSS at our tertiary care referral center between 1987-2015was undertaken...

Pasireotide is a somatostatin analog (SSA) that targets somatostatin receptor subtype 1 (SST1), SST2, SST3, and SST5 with a high affinity. Pasireotide has a better antisecretory effect in acromegaly, Cushing's disease, and neuroendocrine tumors than octreotide. In this study, we compared the effects of pasireotide to those of octreotide in vitro on meningioma primary cell cultures, both alone and in combination with the mTOR inhibitor everolimus. Significant mRNA expression levels of SST1, SST2, and SST5 were observed in 40...

Triptolide is a principal diterpene triepoxide from the Chinese medical plant Tripterygium wilfordii Hook. f., whose extracts have been utilized in dealing with diverse diseases in traditional Chinese medicine for centuries. Recently, the antitumor effect of triptolide has been found in several pre-clinical neoplasm models, but its effect on pituitary corticotroph adenomas has not been investigated so far. In this study, we are aiming to figure out the antitumor effect of triptolide and address the underlying molecular mechanism in AtT20 murine corticotroph cell line...

OBJECTIVE: Most sellar gangliocytomas are discovered with a concurrent pituitary adenoma, also known as a mixed gangliocytoma-adenoma (MGA). MGAs are rare with less than 100 cases reported in the literature and only one previously documented surgical series. As MGAs are radiologically indistinguishable from pituitary adenomas, their diagnosis is often made following surgery. This, combined with the paucity of clinical outcome data for these tumors, makes their diagnosis and management challenging...

: The field of Endocrine Surgery is linked to extraordinary contributions made by Hopkins leaders in surgery including William Stewart Halsted, Harvey Cushing, and John L Cameron. Halsted's contributions to the anatomic basis of thyroid and parathyroid surgery were based on his experimental and clinical work performed at Johns Hopkins Hospital. Halsted's disciple, Harvey Cushing, created the field of modern neurosurgery and recognized the disease and syndrome that are immortalized with his name. The Halstedian principles promulgated and transmitted by John L Cameron to subsequent generations of endocrine surgeons at Hopkins have transformed the field of Endocrine Surgery with the stamp of Johns Hopkins Hospital...

Primary pigmented nodular adrenocortical disease (PPNAD) is a rare cause of Cushing syndrome, especially the isolated form without Carney complex, associated with germline mutations in PRKAR1A, the protein kinase A regulatory subunit type 1 alpha gene. We report a 31-year-old female who presented with secondary amenorrhea, cushingoid appearance, and hypertension without Carney complex. Biochemical laboratory examinations confirmed the ACTH-independent adrenal Cushing syndrome with negative Liddle test. A small right adrenal adenoma of 0...

BACKGROUND: Walter E. Dandy (1886-1946) was an outstanding neurosurgeon who spent his entire career at the Johns Hopkins Hospital. After graduating from medical school in 1910, he completed a research fellowship in the Hunterian laboratory with Harvey Cushing and then joined the Department of Surgery as resident, rising to the rank professor in 1931. Dandy made several contributions that helped building the neurosurgical specialty, most famously the introduction of pneumo-ventriculography to image brain lesions for which he received a Nobel prize nomination...

BACKGROUND: A functional pituitary adenoma can produce multiple anterior-pituitary hormones, such as growth hormone (GH) -producing adenomas (GHoma) with prolactin or thyrotropin stimulating hormone production in the same lineage. However, it is very rare that acromegaly shows subclinical Cushing's disease (SCD) beyond the lineage. Here we describe the involvement of intratumoral coexistence with 2 types of hormone-producing cells associated with different lineage in acromegaly concomitant with SCD...

Cushing disease is a relatively rare cause of Cushing syndrome secondary to a hyperfunctioning pituitary adenoma. In addition to signs and symptoms of hypercortisolism, Cushing disease may present with diverse otolaryngic manifestations, which may guide diagnosis and management. We performed a retrospective chart review of patients who were found to have Cushing disease and who underwent transnasal transsphenoidal surgery for pituitary adenomas between January 1, 2007, and July 1, 2014, at a tertiary academic medical center...
