OBJECTIVE: Germline loss-of-function mutations in succinate dehydrogenase (SDHx) genes results in rare tumor syndromes that include pheochromocytoma, paraganglioma, and others. Here we report a case series of patients with adrenocortical carcinoma (ACC) that harbor SDHx germline mutations. PATIENTS AND RESULTS: We report four unrelated patients with ACC and SDHx mutations. All cases presented with Cushing syndrome and large adrenal masses that were confirmed to be ACC on pathology...

Duplications of the gastric tract are made up of a wide variety of masses throughout the gastrointestinal tract. They may have tubular or cystic morphology. Some duplications are associated with malformations, especially those located in the thorax, which can be associated with intestinal atresia, and malformations of the urinary tract or vetebras (Lund. 2012).

BACKGROUND: Steroid profiling is a promising diagnostic tool for those with adrenal tumors, Cushing syndrome (CS), and disorders of steroidogenesis. Our objective was to develop a multiple-steroid assay using liquid-chromatography, high-resolution, accurate-mass mass spectrometry (HRAM LC-MS) and to validate the assay in patients with various adrenal disorders. METHODS: We collected 24-h urine samples from 114 controls and 71 patients with adrenal diseases. An HRAM LC-MS method was validated for quantitative analysis of 26 steroid metabolites in hydrolyzed urine samples...

BACKGROUND: Exposure to ambient particulate matter (PM) is associated with a number of adverse health outcomes, but potential mechanisms are largely unknown. Metabolomics represents a powerful approach to study global metabolic changes in response to environmental exposures. We therefore conducted this study to investigate changes in serum metabolites in response to the reduction of PM exposure among healthy college students. METHODS: We conducted a randomized, double-blind crossover trial in 55 healthy college students in Shanghai, China...

BACKGROUND: In Europe, synthetic corticosteroids are not allowed in animal breeding for growth-promoting purposes. Nevertheless, a high prevalence of non-compliant urine samples was recently reported for prednisolone, however, without any indication of unauthorized use. Within this context, 20β-dihydroprednisolone and the prednisolone/cortisol ratio have been suggested as potential tools to discriminate between exogenous and endogenous urinary prednisolone. In this study, the validity of these strategies was verified by investigating the plasma pharmacokinetic and urinary excretion profiles of relevant glucocorticoids in bovines, subjected to exogenous prednisolone treatment or tetracosactide hexaacetate administration to induce endogenous prednisolone formation...

PURPOSE: Paraganglioma, a kind of pheochromocytoma originating from embryonic neural crest, is a rare neuroendocrine neoplasm commonly located at extra-adrenal areas such as head, neck, and abdomen. There are a few reports on renal paragangliomas; fewer than 5 reported cases are renal pelvic paragangliomas, including our case. METHODS: Our patient, who had not experienced headache, hypertension, or palpitation, was founded to have a fixed mass in the left renal pelvis incidentally...

A 19-year-old woman presented with painless swelling of the abdomen. During surgery, a giant mass measuring 37 cm×26 cm×12 cm within the distal pancreas invading the spleen was noted. The clinical diagnosis of a solid cystic pseudopapillary tumor of the pancreas was suspected. Distal pancreatectomy, splenectomy, and debulking surgery were performed. Histological examination showed that the tumor infiltrated the spleen and pancreatic parenchyma, and sections of the solid areas revealed a proliferation of spindle-shaped or stellate cells growing in fascicular and storiform patterns within a myxoid intercellular matrix...

We report a case of spontaneous retroperitoneal haemorrhage by bleeding of an adrenal adenoma. Retroperitoneal haemorrhages are rarely encountered in practice, but must be rapidly diagnosed due to the life threatening risk. The etiologies, clinical assessment, management and differential diagnosis of spontaneous retroperitoneal haemorrhages are discussed.

Disturbances of the steroidogenesis or altered peripheral metabolism of steroids may result in severe clinical manifestations. Therefore, prompt diagnosis and initiation of medical treatment are desirable. The diagnostics of disorders of steroid hormone production, metabolism, and action have been previously based on immunoassay tests. However, in a modern medical laboratory, due to low accuracy of immunoassays, this technique is continuously replaced by chromatographic separation methods coupled to mass spectrometric detection systems...

We report the case of a 48-year old woman where probably the intramuscular administration of glucocorticoids by an orthopedist induced a pheochromocytoma crisis. The development of a cardiogenic shock with a cardiac arrest made the use of a venoarterial extra corporeal membrane oxygenation (VA-ECMO, Cardiohelp®, Maquet, Rastatt) necessary. To treat a pulmonary edema under VA-ECMO an Impella-CP® (Abiomed, Aachen) was implanted. A coronary angiography, endomyocardial biopsies and a computer tomography were performed...

Physicians' daily work is accompanied by emotional and physical stress, and 24-h shifts are considered to be a major stressor. Effects of stressors on the hypothalamic-pituitary-adrenal (HPA) axis can be evaluated by estimating the glucocorticoid excretion in urine samples. We characterized the impact of a 24-h working period on the urinary glucocorticoid excretion of physicians and focused on gender differences. 10 females and 12 male physicians collected 24-h urine samples during a 24-h shift ("on-duty") and on a free weekend ("off-duty") that were analyzed by gas chromatography-mass spectrometry...

Gastrointestinal (GI) metastasis from primary lung cancer is a rare clinical finding. Lung cancer most often metastasizes to the brain, bone, liver, and adrenal glands; with gastrointestinal involvement being very rare. We report a case of a 39-year-old female with a diagnosis of poorly differentiated Squamous Cell Carcinoma (SCC) of the lung presenting with dizziness and melena. Esophagogastroduodenoscopy (EGD) showed a bleeding mass in the stomach. Final biopsy report and Immunohistochemistry (IHC) of the specimen were consistent with SCC lung metastasis...

Lymphoma may involve the adrenal glands, but primary lymphoma is rare. Only a few cases have been reported in medical literature. Primary adrenal lymphoma is extremely rare, accounting for <1% of non-Hodgkin lymphomas. We here present a case of a middle-aged female who presented with persistent fever for three weeks. She also reported significant weight loss of more than 10 kgs over the duration of three months. Computed tomography of the thorax and abdomen and pelvis demonstrated bilateral adrenal masses...

Adrenocortical carcinoma (ACC) is a rare disease with a poor prognosis. The presence of a mass syndrome or signs of hormonal hypersecretion often lead to its discovery, but more and more frequently, adrenocortical malignancy is fortuitously discovered as an incidentaloma. Cross-sectional imaging (CT and MRI) often points to the malignant character of the adrenal mass. Needle biopsy is contraindicated. Laboratory testing showing combined hypersecretion of cortisol, androgens or inactive corticosteroid precursors is highly suggestive of ACC...

The hypocholesterolemic protective effect of the dried seed of Astragalus complanatus (ACS) was investigated in rats fed with normal diet, high cholesterol diet (HCD), and HCD plus 70% ethanol extract of ACS (600 mg/kg/day) by oral gavage for four weeks. ACS extract was tested to be rich in antioxidants, which may be contributed to its high content of phenolic compounds. Consumption of ACS remarkably suppressed the elevated total cholesterol (p < 0.01) and LDL-C (p < 0.001) induced by HCD. Chemical constituents of ACS extract were analyzed by ultra-performance liquid chromatography coupled with electrospray ionization orbitrap mass spectrometry and the results showed that the ACS extract mainly consisted of phenolic compounds including flavonoids and flavonoid glycosides...
