Haagensen's Grave signs

2007-11-15T11:58:00.001-08:00

Haagensen's Grave signs are a group of signs that when present in patients of carcinoma breast indicate inoperability.These signs were identified by Haagensen and Stout in a review of the clinical features of patients of breast cancer treated at their hospital in the 1940s. Presence of these signs were associated with a 0% probablity of 5 year cure and 50% risk of local recurrence.The grave signs

Carcinoid Syndrome

Carcinoid syndrome is the most common systemic syndrome caused by carcinoid Tumors. The syndrome describes a symptom complex resulting from the secretion various bioactive amines secreted by carcinoid tumors. In addition to carcinoid syndrome other bioactive substances may also be secreted by the tumor especially in case of foregut carcinoids.These include:GI peptides: Most commonly Pancreatic

Carcinoid Tumors

Oberndorfer introduced the term carcinoid in 1907 to describe tumors that behaved more indolently than adenocarcinomas. These are composed of monotonous sheets of small round cells with uniform nuclei and cytoplasm. They are neuroendocrine tumors and share certain common features with other NETs:Monotonous cellular morphologyNo reliable discriminator of malignancy - invasion and mets are the two

Radiofrequency Ablation Principle High-frequency alternating current applied via an electrode(s) placed within the tissue generates ionic agitation as the ions attempt to change directions and follow the alternating current, thereby creating localised friction heat. Uses heat generated from ionic agitation inside the tissues after application of a RF current. The heat

Definition: It is a device that uses high frequency electromagnetic waves to accelerate charged particles, such as electrons to high energies through a linear tube. Types of linear accelerator design: Standing wave designTraveling wave design In the latter design there is a dummy load, which absorbs the excess power and prevents a reflected wave. In the standing wave design, there

The Manchester system of cervical brachytherapy was one of the most commonly used methods of cervical brachytherapy, till the arrival of computer-based dosimetry. Before a look into the reason why this system was so popular we must look into the history of cervical brachytherapy and dosimetric systems as a whole. Dosimetric systems Any dosimetric system is a set of rules for
