Adenoma

RATIONALE AND JUSTIFICATION OF STUDY Pituitary adenomas are one of the most common intracranial tumors and constitute 10% to 20% of all primary brain tumors. They are generally classified as either “functioning” or “nonfunctioning,” with functioning (secretory) adenomas representing approximately 70% of all pituitary tumors1, 2. Clinically, pituitary adenomas present with a classic semiologic triad related to hypersecretion, hypopituitarism, mass effect (headache, visual disturbances, and hydrocephalus)

author Mark E. Molitch, a medical doctor, discusses the formation of pituitary tumors and the impact they have on the body. He describes how these adenomas form, what symptoms they cause, how they are diagnosed, and how they are treated. In the paper he addresses specific tumors such as Prolactinoma, which encompasses around half of all pituitary adenomas and causes an elevation in prolactin levels, as well as Acromegaly, a growth hormone secreting tumor, and Cushing disease which causes the overproduction

adenoma Its a benign tumour of epithelial origin that is derived from glandular tissue or exhibits clearly defined glandular structures. Adenomas may undergo malignant change. Some show recognizable tissue elements, such as fibrous tissue (fibroadenomas), while others, such as some bronchial adenomas, may produce active compounds giving rise to clinical syndromes. Tumours in certain organs, including the pituitary gland, are often classified by their histological staining affinities, for example

situation. K.Y. recently obtained her bachelors in social science. Family is extremely important to my patient, so taking care of her body and remaining healthy are among her top priorities. She and her family were surprised to find out she had a hepatic adenoma at a routine yearly exam. K.Y. followed instructions and directions from her primary care doctor which landed her at UNC hospital receiving a left sided hepatectomy on 7/8/15. Since the surgical procedure K.Y. has been unable to defecate, is having

What is Adenoma? Adenoma is a non-cancerous tumors which forms on glands in the body. They can grow on parts of the glands in the body such as the breasts, heart, lungs and colon. These tumors do turn cancerous in some cases in which case they are called Adenocarcinomas. The growth of these tumors are usually caused by organs that secrete important hormones and fluids in the body. The moment the epithelial cells that usually secret fluids such as sweat, breast milk and saliva starts to grow gradually

Microsurgical transsphenoid surgery for pituitary adenomas has been the standard treatment for decades [1, 2, 3, 4, 5]. Among various techniques, Sublabial transseptal and transnasal transseptal approachs are the most commonly used [3, 4, 5,]. Since the endoscope became popular in paransal sinus surgery [6, 7], it has increased the interest of neurosurgeons for its use in transsphenoid surgeries. In late nineties a large series of endoscopic pituitary surgeries by Jho and Carrau [8, 9] and Cappabeenca

Introduction Cushing’s syndrome(CS) results from prolonged exposure to excess free glucocorticoids. Around 10-15 per million people are affected by CS every year(1). Most patients with CS have an Adrenocorticotrophic(ACTH)- secreting pituitary adenoma, which is otherwise known as Cushing’s disease. Other causes of CS include adrenal tumours, ectopic ACTH-secreting tumours and exogenous steroid use. Except for exogenous steroid use, the other mentioned causes of CS can all be caused by genetic mutations

fractures for excision of parathyroid adenoma. Abstract: Calcium is important for maintaining numerous physiological processes many of which are important for anaesthesiologists. Primary hyperparathyroidism is an important cause of hypercalcemia, and can be associated with multitude of systemic problems. Our patient presented with severe hyperparathyroidism with hypercalcemia, multiple bone fractures and deformities and was planned for excision of parathyroid adenoma. Management of hypercalcaemia was

charts of 183 patients who were diagnosed with colonic adenoma or carcinoma after having colonoscopy/sigmoidoscopy done in our hospital from 1/1/09 till 12/31/10. Information regarding demographics, HDL level, endoscopy and biopsy findings, site of the lesion and the period between endoscopy and the closest HDL measurement we have in our records. Results: Our study population included 183 patients (66 males and 116 females). 86 patients had adenomas while 96 patients were diagnosed with CRC. The mean
