The Nottingham prognostic index (NPI) is used to determine prognosis following surgery for breast cancer. [1] [2] Its value is calculated using three pathological criteria: the size of the tumour; the number of involved lymph nodes; and the grade of the tumour. [1] It is calculated to select patients for adjuvant treatment.
Fibrocystic breast changes is a condition of the breasts where there may be pain, breast cysts, and breast masses. [1] The breasts may be described as "lumpy" or "doughy". [ 3 ] Symptoms may worsen during certain parts of the menstrual cycle due to hormonal stimulation. [ 1 ]
Staging information that is obtained prior to surgery, for example by mammography, x-rays and CT scans, is called clinical staging and staging by surgery is known as pathological staging. Pathologic staging is more accurate than clinical staging, but clinical staging is the first and sometimes the only staging type.
The SEM is used to set the confidence interval (CI) around an individual score, that is, the observed score plus or minus 1.96 SEMS constitutes the 95% CI. In fact, the reliable change index proposed early by Jacobson and Truax [12] is based on defining change using the statistical convention of exceeding 2 standard errors" (p. 106).
The original scoring system was developed before the invention of pulse oximetry and used the patient's colouration as a surrogate marker of their oxygenation status. A modified Aldrete scoring system was described in 1995 [2] which replaces the assessment of skin colouration with the use of pulse oximetry to measure SpO 2.
The duct widening is commonly believed to be a result of secretory stasis, including stagnant colostrum, which also causes periductal inflammation and fibrosis.However, because nonspecific duct widening is common it might be also coincidental finding in many processes.
The Model for End-Stage Liver Disease, or MELD, is a scoring system for assessing the severity of chronic liver disease.It was initially developed to predict mortality within three months of surgery in patients who had undergone a transjugular intrahepatic portosystemic shunt (TIPS) procedure, [1] and was subsequently found to be useful in determining prognosis and prioritizing for receipt of ...
If the surgery is an emergency, the physical status classification is followed by "E" (for emergency) for example "3E". Class 5 is usually an emergency and is therefore usually "5E". The class "6E" does not exist and is simply recorded as class "6", as all organ retrieval in brain-dead patients is done urgently.
