OBJECTIVE: Data regarding pregnancies in relation to pituitary tumors are limited. The effects of pregnancy on pituitary adenomas and the effects of adenoma itself (hormonal activity, mass effects and pituitary insufficiency) and/or treatment on the ongoing gestation and developing fetus were evaluated. METHODS: The study was a retrospective study. A questionnaire involving questions regarding medical history before index gestation, history of related pregnancy, result of index gestation and postpartum follow-up of the patients was filled by the investigator in one of the eight Referral Endocrinology Centers from Turkey...

BACKGROUND: Accurate anthropometric measurements and critical analysis of growth data allow the clinician to promptly recognize children with short stature. The aim of this study was to determine the frequency of etiological factors causing short stature among children referred to the pediatric endocrinology clinic of Assiut University Children's Hospital, the main tertiary care center in Upper Egypt. METHODS: We conducted this descriptive observational study from May 2012 to December 2015, to analyze 637 children (boys 354, girls 283) with short stature...

REVIEW
Marian Joëls, E Ronald de Kloet
In 1968, Bruce McEwen discovered that (3)H-corticosterone administered to adrenalectomised rats is retained in neurons of hippocampus rather than those of hypothalamus. This discovery signalled the expansion of endocrinology into the science of higher brain regions. With this in mind, our contribution highlights the saga of the brain mineralocorticoid receptor (MR) in three episodes. First, the precloning era dominated by the conundrum of two types of corticosterone-binding receptors in the brain, which led to the identification of the high-affinity corticosterone receptor as the 'promiscuous' MR cloned in 1987 by Jeff Arriza and Ron Evans in addition to the classical glucocorticoid receptor (GR)...

Peptide antibodies, with their high specificities and affinities, are invaluable reagents for peptide and protein recognition in biological specimens. Depending on the application and the assay, in which the peptide antibody is to used, several factors influence successful antibody production, including peptide selection and antibody screening. Peptide antibodies have been used in clinical laboratory diagnostics with great success for decades, primarily because they can be produced to multiple targets, recognizing native wildtype proteins, denatured proteins, and newly generated epitopes...

WHAT IS KNOWN AND OBJECTIVE: Cases of Cushing's syndrome (CS) following ocular steroid use have been reported in recent years, albeit rarely. CASE DESCRIPTION: We report a case of iatrogenic CS in a child induced by fluorometholone-containing eyedrops. Our patient was referred to our endocrinology clinic due to rapid weight gain. His history revealed that 1.5 months previously he had been started on fluorometholone eyedrops. WHAT IS NEW AND CONCLUSION: To the best of our knowledge, no cases of CS have been reported following ocular fluorometholone use...

In volume 85, issue 6 of "Clinical Endocrinology", Aggarwal, et al. published a study titled "Treatment of Hyperthyroidism With Antithyroid Drugs Corrects Mild Neutropenia in Graves' Disease". The authors treated Graves' disease (GD) with mild neutropenia using a thionamide anti-thyroid drug (ATD). From that study we conclude that neutropenia is not uncommon in association with GD and accounts for 14% of cases, and that mild neutropenia does not preclude the use of ATDs.

BACKGROUND: Autoimmune hypothalamitis, which is among the causes of acquired central diabetes insipidus, has been described very rarely in the literature. This condition is probably provoked by the production of anti-vasopressin secreting cells antibodies and anti-hypothalamus antibodies, and is often associated with pituitary or polyendocrine autoimmunity. Correct diagnosis and immediate treatment are essential in order to avoid the progression of the pathological process. CASE DESCRIPTION: A woman diagnosed with central diabetes insipidus 12 year ago, suffering from panhypopituitarism and mild memory deficit came to our attention...

The relationship between serum anti-Müllerian hormone (AMH) levels, body mass index (BMI) and related metabolic factors were investigated in women with polycystic ovary syndrome (PCOS). A total of 691 women aged between 18 and 35 years, referred to the Department of Gynaecological Endocrinology at the University Hospital of Lille between 2009 and 2014 were included: 137 controls and 554 women with PCOS. Mean serum AMH levels were slightly but significantly lower in women with PCOS who were overweight or obese (BMI ≥25) compared with women of normal weight (BMI <25) (P < 0...

BACKGROUND AND AIMS: There is inconsistent evidence that behavioural support to promote smoking reduction is effective at increasing smoking cessation. We examined the effectiveness of a brief physician advice together with four very brief telephone calls in promoting smoking cessation among Chinese men via reduction compared with equivalent advice on diet and exercise. DESIGN: A two-group pragmatic randomized controlled trial. PARTICIPANTS AND SETTING: Male patients attending the Endocrinology and Acupuncture outpatient clinics of a general hospital in Beijing, China...

Magnetic resonance imaging (MRI) is the modality of choice as far as imaging diagnosis of pathologies in the pituitary gland is concerned. Further, the advent of dynamic contrast enhanced (DCE) has enhanced the capability of this modality in detecting minute benign but endocrinologically significant tumors called microadenoma. These lesions are visible with difficulty and a low confidence level in routine MRI sequences, even after administration of intravenous gadolinium. Techniques to enhance the visualization of such foci would be an asset in improving the overall accuracy of DCE-MRI for detection of pituitary microadenomas...

46,XX disorders of sexual development (DSDs) occur rarely and result from disruptions of the genetic pathways underlying gonadal development and differentiation. We present a case of a young phenotypic male with 46,XX SRY-negative ovotesticular DSD resulting from a duplication upstream of SOX9 presenting with a painful testicular mass resulting from ovulation into an ovotestis. We present a literature review of ovulation in phenotypic men and discuss the role of SRY and SOX9 in testicular development, including the role of SOX9 upstream enhancer region duplication in female-to-male sex reversal...

We present the case of a thirty-year-old female patient who was referred to the endocrinology team with an enlarging goitre and biochemical hypothyroidism. She had been dependent on total parenteral nutrition for the previous six years as a result of intestinal failure thought to be caused by possible underlying mitochondrial disease. The patient also suffers from a Desmin myopathy, and at present, the exact aetiology behind her intestinal failure is not certain. The goitre was smooth and had been enlarging slowly over the previous few months...

Hyponatremia, defined as a serum sodium concentration <135mmol/l, is the most common water-electrolyte imbalance encountered in clinical practice. It can lead to a wide spectrum of clinical symptoms, from mild to severe or even life threatening, and is associated with increased mortality, morbidity and length of hospital stay. Despite this, the management of hyponatremia patients remains problematic. The prevalence of hyponatremia in a wide variety of conditions and the fact that hyponatremia is managed by clinicians with a broad variety of backgrounds have fostered diverse institution- and specialty-based approaches to diagnosis and treatment...

BACKGROUND: Anxiety and depressive disorders belong to the most common psychiatric disorders worldwide. They are generally seen in individuals who suffer from chronic diseases, such as diabetes mellitus (DM). The prevalence of depression among diabetics ranges from 8.5% to 32.5%, while that for anxiety it is up to 30%. In this study, we try to compare the mental health problems faced by those with Type I and Type II DM. MATERIALS AND METHODS: Fifty patients diagnosed with Type I diabetes (T1D) and Type II diabetes each presenting to Medicine and Endocrinology Department were assessed with Hamilton Depression Rating Scale (HAM-D) for depression and Hamilton Anxiety Rating Scale (HAM-A) for anxiety...

In the present study, we describe a new method of isolation and culture of human villous and extravillous trophoblasts from term placenta. The cultivation of trypsinized placental villous tissue explants, followed by the isolation of cells from outgrowth islets allows for obtaining a cytotrophoblast subpopulation that is free from contamination by other cell types. Compared to other methods, our protocol is mild, simple and effective, does not request costly reagents and provides isolation of the mononuclear cytotrophoblast cell populations free from contamination by other types of placental cells...

Male infertility is most commonly caused by spermatogenetic failure, clinically noted as oligo- or azoospermia. Today, in approximately 20% of azoospermic patients, a causal genetic defect can be identified. The most frequent genetic causes of azoospermia (or severe oligozoospermia) are Klinefelter syndrome (47,XXY), structural chromosomal abnormalities and Y-chromosomal microdeletions. Consistently with Ohno's law, the human X chromosome is the most stable of all the chromosomes, but contrary to Ohno's law, the X chromosome is loaded with regions of acquired, rapidly evolving genes, which are of special interest because they are predominantly expressed in the testis...
