Primary aldosteronism (PA) is a rare disorder. The majority of patients with PA present with typical features and are easily diagnosed. This disorder is usually diagnosed with hypokalemia, hypertension or an adrenal mass. However, patients with atypical symptoms may present a challenge for diagnosis and treatment. In the present study, a case of PA is described that presented with hypokalemic myopathy simulating polymyositis. The patient was a 44-year-old woman who presented with weakness and difficulty walking...

A 77-year-old man presenting to the emergency department with an acute coronary syndrome was later found to have a phaeochromocytoma. The lateness of this presentation was likely due to the protective α blocking effects of long-term terazosin therapy for his prostatism. α blockers such as terazosin are a well-recognised medical therapy in the perioperative optimisation of phaeochromocytoma because they treat the adrenergic effects of catecholamine release from the tumour such as hypertension. This patient was diagnosed with an ST elevation myocardial infarction (STEMI)...

OBJECTIVE: To illustrate the marked differences between classical endocrinology that distributes hormones to all tissues of the body through the bloodstream and the science of intracrinology, whereby each cell of each peripheral tissue makes a small and appropriate amount of estrogens and androgens from the inactive precursor dehydroepiandrosterone (DHEA), DHEA being mainly of adrenal origin. Because only the inactivated sex steroids are released in the blood, influence in the other tissues is avoided...

OBJECTIVE: Pure androgen-secreting adrenal tumors (PASATs) are extremely rare, most reports involving only a single case. This study examined 9 cases of PASAT, with an attempt to characterize its clinical features and to explore their possible pathogenesis. METHODS: Clinical data of 9 patients with PASAT were retrospectively reviewed. Immunostaining were conducted, and Aryl hydrocarbon receptor-interacting protein (AIP) were amplified and directly sequenced. RESULTS: The onset age of the patients ranged from 3...

BACKGROUND: Giant cell ependymoma of the filum terminale is a rare variant, generally manifested as a well-circunscribed intradural mass with an indolent biological behavior. CASE PRESENTATION: We describe the case of a 48-year-old Mexican female who non-relevant past medical history, that developed a GCE of the filum terminale. Magnetic resonance imaging and computed tomography revealed the presence of an intra-axial tumor extending from L3 to L5 with extra-medullary invasion...

INTRODUCTION: Giant cystic pheochromocytoma (>10cm) is rare with only a few cases described in the literature. Preoperative diagnosis is very difficult because clinical, biochemical and radiologic finds are usually not consistent with a pheochromocytoma. Open surgery is traditionally the gold standard. CASE PRESENTATION: A 51 year-old male patient resorted to surgery department with an adrenal cystic incidentaloma. He was asymptomatic, mild hypertension easily controlled, with increased plasma fractionated metanephrines...

In the current investigation, the potential alleviating effects of tianeptine against bone loss induced in ovariectomized (OVX) rats was determined. Two weeks following a bilateral ovariectomy operation, tianeptine treatment (12.5 and 25mg/kg/twice/d) was initiated and continued for twenty-eight consecutive days. Changes in serum and urinary bone turnover biomarkers and osteoclastogenesis-inducing factors were estimated. The femoral bone mineral content was estimated using inductively-coupled-plasma mass spectrometry...

A 52-yr-old female Nile hippopotamus ( Hippopotamus amphibious ) was presented for acute onset anorexia, depression, lethargy, instability, and weakness in the pelvic limbs. Clinical signs were rapidly progressive, despite empiric therapy with anti-inflammatory medications, resulting in the death of the animal. Gross necropsy evaluation revealed two tan, firm masses in the cerebellum and mesencephalon and a single mass in the right cranial adrenal gland. All three masses had a similar histologic morphology, and immunohistochemical investigation confirmed the general diagnosis of an adenocarcinoma, but the exact cell of origin remains unclear...

Adrenal vein sampling (AVS) is essential in differentiating unilateral from bilateral sources of aldosterone excess in primary aldosteronism (PA). However, its ability to predict blood pressure (BP) improvement after adrenalectomy has not been well studied. This is a retrospective observational study of 119 patients who underwent AVS by sequential technique followed by adrenalectomy for PA at the Hospital of the University of Pennsylvania from 1997 to 2015. Median age was 52 years (interquartile range 44-59), 67% were male and median duration of hypertension was 10 (interquartile range 6-20) years...

BACKGROUND: Hereditary angioedema caused by C1-inhibitor deficiency (C1-INH-HAE) is a rare, autosomal dominant disorder. C1-INH-HAE is characterized by edema-formation, which may occur in response to stress. The individual's response to stress stimuli is partly genetically determined. Activation of the hypothalamic-pituitary-adrenal axis results in the release of cortisol. In turn, the secreted gluco- and mineralocorticoids affect the metabolism, as well as the cardiovascular and immune systems...

CONTEXT: Medullary thyroid carcinomas (MTCs) complicated by ectopic Cushing's syndrome have a poor prognosis, partially due to the difficulties to control hypercortisolism by adrenal blocking drugs. Recent reports (including the initial follow-up of this patient) have suggested that tyrosine kinase inhibitors (TKIs) may be a therapeutic option due to an antisecretory action on ACTH. However, there is a lack of long-term follow-up studies. CASE DESCRIPTION: We report the case of a 58 year-old man with a MTC-related Cushing's syndrome resistant to a combination of several anticortisolic drugs...

Beckwith-Wiedemann syndrome (BWS) is a genetic overgrowth and cancer predisposition syndrome, associated with both benign and malignant adrenal findings. Literature review and an institutional case series elucidate the wide spectrum of adrenal findings in BWS patients. The altered expression of the 11p15 region is likely related to adrenal gland hyperplasia and growth dysregulation. Given the absence of guidelines for managing adrenal findings in BWS, we propose a systematic approach to adrenal findings in BWS patients, to allow for maximum detection of potentially malignant pathology without posing additional risk to patients...

Adrenal lesions are routinely encountered incidentally in clinical practice. Although most of these lesions are benign, malignancy needs to be excluded. Therefore, the initial clinical workup is to exclude aggressive characteristics suggesting malignancy and to identify characteristics predictive of the most common benign lesion, an adrenal adenoma. Predicting a benign adenoma using a variety of imaging modalities has been widely studied using unenhanced computed tomography (CT), contrast enhanced CT, and magnetic resonance (MR) imaging...

Living kidney donation is associated with a small but significant increase in cardiovascular mortality. In addition, mildly decreased kidney function is associated with an increase of left ventricular mass and with cardiovascular disease in patients with chronic kidney disease. To investigate this association, we evaluated the impact of mildly decreased kidney function after living kidney donation on subclinical cardiac structural and functional changes. In this prospective cohort study, cardiac and renal magnetic resonance imaging and laboratory analyses were performed in 23 living kidney donors (mean age 54±10 years, 52% male) before donation and at 4 and 12 months after nephrectomy...

REVIEW
Osnat Hakimi, Luiz-Claudio Cameron
BACKGROUND: Infertility has been described as a devastating life crisis for couples, and has a particularly severe effect on women, in terms of anxiety and depression. Anovulation accounts for around 30% of female infertility, and while lifestyle factors such as physical activity are known to be important, the relationship between exercise and ovulation is multi-factorial and complex, and to date there are no clear recommendations concerning exercise regimes. OBJECTIVES: The objective of this review was to systematically assess the effect of physical activity on ovulation and to discuss the possible mechanisms by which exercise acts to modulate ovulation in reproductive-age women...

We present a patient with a 16 cm adrenocortical carcinoma that underwent a left adrenalectomy en bloc with resection of the involved segment of the left renal artery. A splenectomy and splenorenal bypass was performed to revascularize the left kidney. To our knowledge, this is the first instance in the literature of a splenorenal arterial bypass being reported for renal revascularization during an extirpative oncologic procedure. A 64-year-old male patient, with history significant for adrenocortical carcinoma, status post prior right adrenalectomy with partial right nephrectomy, presented for an elective left adrenalectomy...
