Pituitary Sarcoidosis in a Pediatric Patient Successfully Treated With Adalimumab and Methotrexate
Journal of Investigative Medicine High Impact Case Reports, 2021 Neurosarcoidosis is a rare phenomenon in the pediatric population, with only a few cases reported in the literature worldwide. While hypothalamo-pituitary involvement is known to occur, direct infiltration of the pituitary gland and isolated anterior ...

Stability and Hopf bifurcation analysis for the hypothalamic-pituitary-adrenal axis model with memory [PDF]
, 2016 This paper generalizes the existing minimal model of the hypothalamic-pituitary-adrenal (HPA) axis in a realistic way, by including memory terms: distributed time delays, on one hand and fractional-order derivatives, on the other hand. The existence of a unique equilibrium point of the mathematical models is proved and a local stability analysis is ...

Stability and Hopf bifurcation analysis of a four-dimensional hypothalamic-pituitary-adrenal axis model with distributed delays [PDF]
, 2017 A four-dimensional mathematical model of the hypothalamus-pituitary-adrenal (HPA) axis is investigated, incorporating the influence of the GR concentration and general feedback functions. The inclusion of distributed time delays provides a more realistic modeling approach, since the whole past history of the variables is taken into account.

Magnetic resonance imaging (MRI) findings in isolated growth hormone deficiency
The Turkish Journal of Pediatrics, 1998 In this study the presence of pituitary-hypothalamic abnormalities was searched by magnetic resonance (MR) imaging in 30 children (18 males and 12 females, aged 7.4 to 23 years) with isolated growth hormone deficiency (IGHD).

Reproductive Biology and Endocrinology, 2009 Background A series of studies showed the presence of substantial amount of nerve fibers and their close relationship with the anterior pituitary gland cells. Our previous studies have suggested that aside from the classical theory of humoral regulation,

Endocrinology, Diabetes & Metabolism Case Reports, 2019 Patients treated with immunosuppressive drugs, especially methotrexate (MTX), rarely develop lymphoproliferative disorders (LPDs), known as MTX-related LPD (MTX–LPD). The primary site of MTX–LPD is often extranodal. This is the first reported case of MTX–

Indian Journal of Endocrinology and Metabolism, 2013 Tumours metastasizing to the pituitary gland are uncommon. Symptomatic patients with pituitary metastases can present with diabetes insipidus, headache, visual field defects and/or anterior pituitary hormonal dysfunction.

Continuous and Pulsed Experiments with Numerical Simulation to Dissect Pituitary Gland Tumour by Using Liquid Jet [PDF]
Engineering Letters, 2017, 2019 Endoscopic endonasal surgery is a minimal invasive surgery that has been used to dissect pituitary gland tumour via curettes with the help of endoscope. However, this type of surgery has a high risk of failure because curettes may cause damages to blood vessels and optical nerves that lead to more complication for the patient.

Development of the anterior pituitary: diverse lineages of the stem/progenitor cells
Endocrine JournalThe pituitary gland is endocrine tissue composed of two distinct parts with different origins: the adenohypophysis (adenohypophyseal placode origin) and the neurohypophysis (neuroectoderm origin). Differentiation of endocrine cells in the pituitary gland

Angle-Closure Detection in Anterior Segment OCT based on Multi-Level Deep Network [PDF]
, 2019 Irreversible visual impairment is often caused by primary angle-closure glaucoma, which could be detected via Anterior Segment Optical Coherence Tomography (AS-OCT). In this paper, an automated system based on deep learning is presented for angle-closure detection in AS-OCT images.
