Background: Adrenal incidentaloma refers to the incidental finding of a tumor in the adrenal gland, where nonfunctional forms are the most common variant. Myelolipoma is a rare (0.08-0.4%) occurrence characterized by adipose and hematopoietic tissue. The aim of this case report is to describe the diagnosis and appropriate management of a myelolipoma in an asymptomatic patient, which was originally considered an incidental hepatic hemangioma prior to being identified as a giant adrenal adenoma. Case description: The patient was a 54 year old obese female with a recent diagnosis of diabetes type II and dyslipidemia with recent ultrasound imaging suggestive of a hepatic hemangioma...

BACKGROUND: Cutaneomeningospinal angiomatosis or Cobb syndrome is a rare, not well understood phacomatosis that features metameric cutaneous and spinal arteriovenous malformations (AVMs). The first case was described in Boston in 1915, and since then, few more cases have been reported in the English literature. No case was found to be from Argentina. CASE DESCRIPTION: The authors present a 16-year-old boy with acute quadriparesis and respiratory failure who was diagnosed as Cobb syndrome and treated with microsurgery alone with very good results...

The Johns Hopkins Hunterian Neurosurgical Laboratory at the Johns Hopkins University School of Medicine was created in 1904 by Harvey Cushing and William Halsted and has had a long history of fostering surgical training, encouraging basis science research, and facilitating translational application. Over the past 30 years, the laboratory has addressed the paucity of brain tumor therapies. Pre-clinical work from the laboratory led to the development of carmustine wafers with initial US Food and Drug Administration (FDA) approval in 1996...

We report the identification, pathogenesis, and transmission of a novel polyomavirus in severe combined immunodeficient F344 rats with null Prkdc and interleukin 2 receptor gamma genes. Infected rats experienced weight loss, decreased fecundity, and mortality. Large basophilic intranuclear inclusions were observed in epithelium of the respiratory tract, salivary and lacrimal glands, uterus, and prostate gland. Unbiased viral metagenomic sequencing of lesioned tissues identified a novel polyomavirus, provisionally named Rattus norvegicus polyomavirus 2 (RatPyV2), which clustered with Washington University (WU) polyomavirus in the Wuki clade of the Betapolyomavirus genus...

Werner syndrome is a rare genetic disease characterized by progeria, diabetes mellitus, cataracts and various types of malignancy. However, there are few reports showing adrenal cortex cancer in subjects with Werner syndrome. We herein report an extremely rare case of Werner syndrome accompanied by adrenal cortex cancer. Based on the data obtained from blood samples, computed tomography, magnetic resonance imaging and (131)I adosterol scintigraphy, we diagnosed this subject with adrenal cortex cancer and Cushing's syndrome...

INTRODUCTION: Double adenomas in the pituitary gland are a rare occurrence. The ability to cure a hormone-producing adenoma with surgery is dependent on the ability to identify and completely remove the correct adenoma. The relative frequency of each subtype of hormone-secreting adenomas confirmed with magnetic resonance image (MRI), surgery and immunohistochemistry is not defined. METHODS: Following PRISMA guidelines, we performed a systematic review of PubMed Central, Google Scholar, Scopus Database, Cochrane database and Science Research, using the key-words: "double pituitary adenomas", "multiple pituitary adenomas" and only papers where multiple or truly separate double pituitary adenomas were identified pre-surgically by MRI and/or confirmed by pathology/immunohistochemistry staining were included...

Many different non systemic corticosteroid administrations can cause iatrogenic Cushing's Syndrome (CS). We herein report a case series of iatrogenic CS from keloid scars treatment and aesthetic regimen called mesotherapy. Our first patient developed CS after having exceeded recommended dose of intralesional injection of Triamcinolone Acetonide (TAC). Second case presented with CS followed by unidentified mesotherapy treatment for local fat reduction. Subcutaneous injections of dexamethasone were found to be the part of mesotherapy regimen in one case...

Pasireotide is a somatostatin analog (SSA) that targets somatostatin receptor subtype 1 (SST1), SST2, SST3, and SST5 with a high affinity. Pasireotide has a better antisecretory effect in acromegaly, Cushing's disease, and neuroendocrine tumors than octreotide. In this study, we compared the effects of pasireotide to those of octreotide in vitro on meningioma primary cell cultures, both alone and in combination with the mTOR inhibitor everolimus. Significant mRNA expression levels of SST1, SST2, and SST5 were observed in 40...

An 81-year-old man with Cushing syndrome was referred for a Ga-DOTATATE PET/CT study to investigate for an ectopic source of adrenocorticotropic hormone. The scan demonstrated mildly increased octreopeptide uptake at a rectal mass and focal uptake at multiple regions throughout the bone marrow of the axial skeleton, consistent with metastases. A subsequent F-FDG PET/CT study was performed for further evaluation and demonstrated markedly increased metabolism at the previously identified rectal mass, in addition to the liver and multiple regions throughout the skeleton...

BACKGROUND: The mechanisms of brain death (BD)-induced lung injury remain incompletely understood, as uncertainties persist about time-course and relative importance of mechanical and humoral perturbations. METHODS: Brain death was induced by slow intracranial blood infusion in anesthetized pigs after randomization to placebo (n = 11) or to methylprednisolone (n = 8) to inhibit the expression of pro-inflammatory mediators. Pulmonary artery pressure (PAP), wedged PAP (PAWP), pulmonary vascular resistance (PVR) and effective pulmonary capillary pressure (PCP) were measured 1 and 5 hours after Cushing reflex...

Cushing's syndrome (CS) is common after oral steroid use and has also been reported following topical or inhaled use, but it is extremely uncommon after intranasal administration. This is the case of a 6-year-old child who developed Cushing's syndrome after intranasal application of dexamethasone sodium phosphate for a period of 6 months. Pediatricians and other clinical practitioners should be aware that high-dose and long-term nasal steroid administration may cause iatrogenic Cushing's syndrome characterized by complications of glucocorticoid excess as well as serious and even life-threatening complications of adrenal insufficiency...

OBJECTIVE: Angiopoietin-like 4 (ANGPTL4) is a fasting-induced inhibitor of lipoprotein lipase (LPL) and a regulator of plasma triglyceride metabolism. Here, we examined the kinetics of Angptl4 induction and tested the hypothesis that ANGPTL4 functions physiologically to reduce triglyceride delivery to adipose tissue during nutrient deprivation. METHODS: Gene expression, LPL activity, and triglyceride uptake were examined in fasted and fed wild-type and Angptl4(-/-) mice...

We present an experimental method including error analysis for the measurement of the density and compressibility of cells and microbeads; these being the two central material properties in ultrasound-based acoustophoretic applications such as particle separation, trapping, and up-concentration. The density of the microparticles is determined by using a neutrally-buoyant selection process that involves centrifuging of microparticles suspended in different density solutions, CsCl for microbeads and Percoll for cells...

BACKGROUND: To support antibiotic prescribing for both hospital and community-based health professionals working in remote North Western Australia, a multidisciplinary Antimicrobial Stewardship (AMS) Committee was established in 2013. This Committee is usually focused on hospital-based prescribing. A troubling increase in sulfamethoxazole/trimethoprim resistance in Staphylococcus aureus antibiograms from 9 to 18% over 1 year prompted a shift in gaze to community prescribing. WHAT WE DID: Finding a paucity of relevant research, we first investigated contextual factors influencing local prescribing...

BACKGROUND: Transsphenoidal surgery is the gold standard for pituitary adenoma resection. However, despite advances in microsurgical and endoscopic techniques, some pituitary adenomas can be challenging to cure. OBJECTIVE: To determine whether, in patients undergoing transsphenoidal surgery for pituitary adenoma, intraoperative ultrasound is a safe and effective technological adjunct. METHODS: The PubMed database was searched between January 1996 and January 2016 to identify relevant publications that (1) featured patients undergoing transsphenoidal surgery for pituitary adenoma, (2) used intraoperative ultrasound, and (3) reported on safety or effectiveness...

OBJECTIVE: Previous studies have demonstrated the association between Cushing's syndrome (CS), obstructive sleep apnea (OSA), and the risk factors for OSA, but rarely provided the evidence within a large population. Using the Taiwan National Health Insurance Research Database, we attempted to investigate the association between CS and OSA, and to provide persuading evidences. METHODS: In our study, 1612 patients with CS and 1612 age-, sex-, and comorbidities-matched controls were included, and followed up to the end of 2011...
