Summary: Cushing's syndrome is an endocrine disorder that causes anovulatory infertility secondary to hypercortisolism; therefore, pregnancy rarely occurs during its course. We present the case of a 24-year-old, 16-week pregnant female with a 10-month history of unintentional weight gain, dorsal gibbus, nonpruritic comedones, hirsutism and hair loss. Initial biochemical, hormonal and ultrasound investigations revealed hypokalemia, increased nocturnal cortisolemia and a right adrenal mass. Read More

Aims/introduction: An increased risk of diabetes mellitus has been reported in primary aldosteronism, but the pathogenesis of glucose intolerance between the primary aldosteronism subtypes remains unclear. This study aimed to evaluate glucose metabolism in oral glucose tolerance test between aldosterone-producing adenoma and idiopathic hyperaldosteronism, and characterize patients with improved glucose intolerance following primary aldosteronism treatment.

Materials And Methods: Oral glucose tolerance test was performed in 116 patients who were diagnosed with primary aldosteronism and received adrenal venous sampling for subtyping. Read More

Background Dual-energy CT allows virtual noncontrast (VNC) attenuation and iodine density measurements from contrast material-enhanced examination, potentially enabling adrenal lesion characterization. However, data regarding diagnostic performance remain limited, and combined diagnostic values have never been investigated. Purpose To determine whether VNC attenuation, iodine density, and combination of the two allow reliable differentiation between adrenal adenomas and metastases. Read More

Background: Adrenal lesions diagnosed during pregnancy remain rare, and their management is challenging because of maternal physiologic modifications, restricted imaging investigations, and contraindications to several treatments. Surgical issues of adrenalectomy during pregnancy and consequences on perinatal outcomes are poorly described. We therefore aimed to report maternal and fetal outcomes after adrenalectomy during pregnancy. Read More

Metabolic reprogramming is a cellular process contributing to carcinogenesis. However, it remains poorly understood in adrenal cortical carcinoma (ACC), an aggressive malignancy with overall poor prognosis and limited therapeutic options. We characterized the metabolic phenotype of ACC, by examining the immunoprofile of key proteins involved in glucose metabolism, hexokinase (HK1), pyruvate kinase (PKM1, PKM2), succinate dehydrogenase (SDHB), and phospho-S6 ribosomal protein (pS6), in a tissue microarray of 137 adrenal cortical tissue samples.

Background: Current recommendations using Hounsfield units (HU) ≤ 10 to identify adrenal adenomas on unenhanced computed tomography (CT) miss 10-40% of benign adenomas. We sought to determine if changing HU threshold and adding absolute percent contrast washout (APW) criteria would identify adrenal adenomas better than current recommendations.

Methods: Imaging characteristics were compared between patients with adenomas (n = 128) and those with non-adenomas (n = 54) after unilateral adrenalectomy. Read More

From the Departments of Diagnostic Radiology.

Purpose: The aims of the study were to assess the typical and atypical radiologic features of pathologically proven adrenal adenomas and to determine the relationship between the radiologic and histopathologic classification.

Methods: We retrospectively studied 156 pathologically proven adrenal adenomas in 154 patients from our institutional databases who have computed tomography (CT) and/or magnetic resonance imaging (MRI) examinations before intervention. We determined the histopathologic diagnosis (typical or atypical) using Weiss scoring and classified the adenomas radiologically into typical, atypical, or indeterminate based on lesion size, precontrast CT attenuation, absolute percentage washout, calcification, and necrosis.

Adrenal venous sampling is the standard of care for identifying patients with unilateral primary aldosteronism, which is often caused by an aldosterone producing adenoma and can be cured with surgery. The numerous limitations of adrenal venous sampling, including its high cost, scarce availability, technical challenges, and lack of standardized protocols, have driven efforts to develop alternative, non-invasive tools for the diagnosis of aldosterone producing adenomas. Seminal discoveries regarding the pathogenesis of aldosterone producing adenomas made over the past decade have leveraged hypotheses-driven research of steroid phenotypes characteristic of various aldosterone producing adenomas.

Herein we reviewe the importance of age, gender, and BMI as determinants of surgical success based on the recent findings including a nation-wide, multicenter study in Japan (JPAS/JRAS).

Primary aldosteronism (PA) is a common cause of secondary hypertension caused by excessive and inappropriate secretion of the hormone aldosterone from one or both adrenal glands. The prevalence of PA ranges from 10% in the general hypertensive population to 20% in resistant hypertension, yet only a small fraction of patients is diagnosed. Disease and symptom recognition, screening in indicated populations, multidisciplinary communication, and appropriate imaging and biochemical workup can identify patients who might benefit from effective and targeted treatment modalities.

Primary aldosteronism (PA) is characterized by autonomous aldosterone production by renin-independent mechanisms and is most commonly sporadic. While 60-70% of sporadic PA can be attributed to bilateral hyperaldosteronism, the remaining 30-40% is caused by a unilateral aldosterone-producing adenoma (APA). Somatic mutations in or near the selectivity filter the gene (encoding the potassium channel GIRK4) have been implicated in the pathogenesis of both sporadic and familial PA. Read More

MicroRNAs, the endogenous mediators of RNA interference, interact with the renin-angiotensin-aldosterone system, regulate aldosterone secretion and aldosterone effects. Some novel data show that the expression of some microRNAs is altered in primary aldosteronism, and some of these appear to have pathogenic relevance, as well. Differences in the circulating microRNA expression profiles between the two major forms of primary aldosteronism, unilateral aldosterone-producing adenoma and bilateral adrenal hyperplasia have also been shown.

Background: Different techniques for laparoscopic adrenalectomy have been proposed with the lateral transperitoneal approach and posterior retroperitoneal approach being the two more frequently minimally invasive surgeries in most of the clinics. There are no sufficient studies in which the results of lateral transperitoneal and posterior retroperitoneal approaches in synchronous bilateral laparoscopic adrenalectomy have been compared. In the current study, we aimed to report our multicenter results of the lateral transperitoneal and posterior retroperitoneal synchronous bilateral laparoscopic adrenalectomy experience in patients who had different bilateral adrenal pathologies and to compare the outcomes of these two different operative procedures.
