Polycystic ovarian syndrome (PCOS) is a common reproductive disorder frequently associated with a substantial risk factor for ovarian hyperstimulation syndrome (OHSS). Dopamine receptor 2 (D2) agonists, like Cabergoline (Cb2), have been used to reduce the OHSS risk. However, lutein granulosa cells (LGCs) from PCOS patients treated with Cb2 still show a deregulated dopaminergic tone (decreased D2 expression and low dopamine production) and increased vascularization compared to non-PCOS LGCs. Therefore, to understand the PCOS ovarian physiology, it is important to explore the mechanisms that underlie syndrome based on the therapeutic effects of Cb2...

AIM: The prevalence and risk factors of subclinical haemorrhage on non-functional adenomas (NFA) remain controversial. The primary aim of our study was to assess the incidence of subclinical haemorrhage (SH) and the secondary objectives were to evaluate the risk factors of SH and the impact of SH on pituitary function at diagnosis. PATIENTS AND METHODS: This retrospective transversal analysis included 95 patients between January 2012 and December 2014. The patients included in this series were all adults (>18 years of age), who presented a non-functional adenoma confirmed by an endocrinological evaluation and on dedicated MRI pituitary imaging...

BACKGROUND: Prolactinomas are typically treated non-surgically with a dopamine agonist. However, once the tumor shrinks, adjacent eloquent structures such as the optic apparatus can become skeletonized and herniate into the dilated parasellar space. CASE DESCRIPTION: We describe here a 48-year-old man with a prolactin-secreting macroadenoma treated with cabergoline who presented with progressive bitemporal hemianopsia. MRI showed no recurrence of disease and a stretched optic chiasm herniating into an empty sella...

Background: Prevention of severe Ovarian Hyperstimulation Syndrome (OHSS), a potentially fatal complication of controlled ovarian hyperstimulation has been the aim of all fertility experts. Various pharmacologic and non-pharmacologic interventions have been instituted but the results have been conflicting. These preventive strategies were administered in isolation or as a combination of few aiming to eliminate this iatrogenic sequel. This study aimed to eliminate severe OHSS by multipronged approach incorporating almost all preventive modalities available in patients at high risk for this dreadful complication...

BACKGROUND: Breast cancer is one of the common causes of mortality for women in Iran and other parts of the world. The substantial increasing rate of breast cancer in both developed and developing countries warns the scientists to provide more preventive steps and therapeutic measures. This study is conducted to investigate the impact of neurotransmitters (e.g., Dopamine) through their receptors and the importance of cancers via damaging immune system. It also evaluates dopamine receptors gene expression in the women with breast cancer at stages II or III and dopamine receptor D2 (DRD2) related agonist and antagonist drug effects on human breast cancer cells, including MCF-7 and SKBR-3...

INTRODUCTION: Prolactinomas may rarely present with meningitis and cerebrospinal fluid (CSF) rhinorrhea secondary to erosion of the wall of the sella turcica. It is even more un-common for this abnormal communication to be caused by an ectopic prolactinoma arising from the sphenoid sinus and eroding into the sella. This atypical growth pattern makes diagnosis very difficult, as there may be no displacement of the normal pituitary gland. The authors present the first reported case of a patient with an ectopic prolactinoma presenting primarily with meningitis, and discuss the management strategy as well as surgical and non-surgical treatment options for these patients...

PURPOSE: To determine the serotonergic (5HT) receptor subtype mediating the contraction of bovine posterior ciliary arteries (BPCAs) in vitro. METHODS: Longitudinal isometric tension was measured in BPCA strips (4-5 mm) mounted in 25 mL organ baths containing oxygenated Krebs solution at 37°C. Cumulative contractile concentration-response (C-R) curves were generated for various 5-HT agonists to assess their potencies and maximal degrees of contraction. Multiple agonist C-R curves were also constructed in the presence and absence of receptor-selective antagonists to determine antagonist potencies using Schild plots...

BACKGROUND: The approach to acromegalic patients with persistent acromegaly after surgery and inadequate response to first-generation somatostatin receptor ligands (SRLs) should be strictly tailored. Current options include new pituitary surgery and/or radiosurgery, or alternative medical treatment with SRLs high dose regimens, pegvisomant (PEG) as monotherapy, or combined therapy with the addition of PEG or cabergoline to SRLs. A new pharmacological approach includes pasireotide, a second-generation SRL approved for patients who do not adequately respond to surgery and/or for whom surgery is not an option...

Uterine fibroids (UFs) are the most common tumors of the female genital tract. The effect of UFs on the quality of life and the overall cost of treatment are significant issues worldwide. Tumor size and location are the two specific factors which influence the occurrence of symptoms, the need for, and method of, treatment (some tumors require surgery while some can be treated with selected drugs). Primary prevention and treatment of early UF disease are worthy goals that might have a great impact on health care systems...

Cluster-like headache may be associated with pituitary tumors, mostly prolactinomas. Pituitary imaging and prolactin measurement should be assessed in patients presenting with cluster-like headaches with atypical features or unsatisfactory response to treatment. Furthermore, large pituitary adenomas with moderate increase in prolactin levels should prompt prolactin dilutions to avoid "hook effect".

Severe ovarian hyperstimulation syndrome (OHSS) is a potentially life-threatening complication of assisted reproductive technology. Herein, we report the case of an infertile couple, with the husband being azoospermic, who underwent in-vitro fertilisation and intracytoplasmic sperm injection at our institute. The woman presented with late OHSS 7 days after embryo transfer. Inpatient management was performed with intensive surveillance. Oral cabergoline was started prophylactically but was replaced by the vaginal route due to intolerance...

BACKGROUND: Uterine fibroids occur in up to 40% of women aged over 35 years. Some are asymptomatic, but up to 50% cause symptoms that warrant therapy. Symptoms include anaemia caused by heavy menstrual bleeding, pelvic pain, dysmenorrhoea, infertility and low quality of life. Surgery is the first choice of treatment. In recent years, medical therapies have been used before surgery to improve intraoperative and postoperative outcomes. However, such therapies tend to be expensive.Fibroid growth is stimulated by oestrogen...

Human induced pluripotent stem cells (hiPSCs) are expected to be both a revolutionary cell source for regenerative medicine and a powerful tool to investigate the molecular mechanisms underlying human cell development in vitro. In the present study, we tried to elucidate the steroidogenic differentiation processes using hiPSC-derived intermediate mesoderm (IM) that is known to be the origin of the human adrenal cortex and gonads. We first performed chemical screening to identify small molecules that induce steroidogenic differentiation of IM cells expressing Odd-skipped related 1 (OSR1), an early IM marker...

The purpose of this review is to analyze current medical strategies in the prevention of ovarian hyperstimulation syndrome (OHSS) during ovarian stimulation for in vitro fertilization. Owing to contemporary preventive measures of OHSS, the incidence of moderate and severe forms of the syndrome varies between 0.18% and 1.40%. Although none of medical strategies is completely effective, there is high-quality evidence that replacing human chorionic gonadotropin (hCG) by gonadotropin-releasing hormone (GnRH) agonists after GnRH antagonists and moderate- quality evidence that GnRH antagonist protocols, dopamine agonists and mild protocols reduce the occurrence of OHSS...

Presently, the standard of care for prolactinomas, a type of pituitary adenoma, is dopaminergic agents such as bromocriptine and cabergoline. However, dopaminergic agents may induce fibrosis of cardiac valves leading to valvular insufficiency, necessitating surgical treatment of prolactinoma. Fibrosis of prolactinoma can be induced by prolonged medical treatment with bromocriptine, and this usually occurs after years of treatment. In comparison to bromocriptine, there have been no reports of cabergoline-induced fibrosis of prolactinoma...

We report on a 27-year-old male patient presenting with renal colic secondary to hyperparathyroidism. Further investigations confirmed a diagnosis of type 1 multiple endocrine neoplasia and revealed a 2.0 cm pancreatic neuroendocrine tumour as well as a pituitary macroadenoma with significantly elevated prolactin levels. The patient underwent three-gland parathyroidectomy, a left pancreatectomy, and received dopamine agonist treatment. Genetic testing revealed a novel germline heterozygote missense mutation in the MEN1 gene (p...
