Abstract Background The purpose of this study is to evaluate the influence anti-vascular endothelial growth factor (VEGF) in appearance or progression epiretinal membranes (ERMs) age-related macular degeneration (ARMD) and investigate confounding factors causing ERMs. Methods Seventy-six eyes that were treated for more than 36 months from first anti-VEGF injection assessed. Binary logistic regr...

A 51-year-old female was diagnosed preoperatively to have a pheochromocytoma producing ACTH. This diagnosis was based upon her paroxysmal hypertension, hyperpigmentation, and hypokalemia. Elevated levels of serum and urine corticosteroids, plasma ACTH, urinary VMA, and catecholamines fell after a right adrenal pheochromocytoma was removed. Subsequently this tumor was found to have a high conten...

Malignant pheochromocytoma is a rare disease with a high mortality. Surgical removal is usually curative while chemotherapy and radiotherapy are palliative treatments. A case of metastatic malignant pheochromocytoma of the right adrenal gland is presented who had fluctuating blood pressure with episodic headache and raised urinary VMA levels. Thoraco-abdominal resection of the tumour resulted i...

We studied the limiting spectral distribution of large-dimensional sample covariance matrices of a stationary and invertible VARMA(p,q) model. Relationship of the power spectral density and limiting spectral distribution of large population dimensional covariance matrices of ARMA(p,q) is established. The equation about Stieltjes transform of large-dimensional sample covariance matrices is also ...

The metabolic pathways for the catecholamines and their metabolites are presented. Typical urinary metabolite patterns are illustrated for cases of neuroblastoma and pheochromocytoma. Representative methods for perform­ ing the analysis of some catecholamine compounds and their metabolites are outlined. Pheochromocytomas are catecholamine producing tumors derived from chromaffin cells. In these...
