Sensitivity And Specificity Of Colonoscopy
What is the sensitivity and npv of pancreas protocol ct scan in the detection of pancreatic cancer in the symptomatic patient?
Unclear question: I do not understand your question. But microscopic colitis is a specific condition that is most commonly related to medications, though some conditions predispose you to developing it (Celiac may be one). Milk sensitivity? - if you mean lactose intolerance then this is common and separate from Celiac. Everyone that drinks enough milk will have symptoms. ...Read moreSee 1 more doctor answer
High: Since the test is looking for the virus itself it is very specific. There should be no false positives of titers that are significantly above the minimum of detection (of course some human error is always possible). Similarly, since it amplifies any detected viral RNA a million-fold, it is also very sensitive. ...Read more
Symptoms or sign?: Symptoms: gas, bloat, cramps, loose stool, weight loss (or gain), fatigue (perhaps due to iron deficiency with or without anemia), muscle, bone or joint pain (perhaps due to fit d def; can be associated with lots of other nonspecific symptoms. Signs: pallor, muscle loss, abdominal distension, edema, numbness or tingling, others. Not everyone with the above symptoms and signs has celiac sprue. ...Read more
In layman's terms what does this mean: "study for detecting pancreatic cancer states: sensitivity of mrcp with respect to diagnosis PC was 84 percent and specificity was 97%." A study done on detecting PC.
Screen vs Confirm: Sensitivity means that if you had 100 people with biopsy proven PC, then 84 out of the 100 people with PC had a (+) test. Specificity means that if you had a (+) test result there is a 97% probability that you have PC and a 3% probability that you have a "false positive" (which means you do not have PC). High sensitivity tests are used to screen for a condition whereas high specificity confirms. ...Read moreSee 1 more doctor answer

Q for radiologist What is the sensitivity of CT scan when patient is symptomatic for lung cancer with weight loss and fatigue?
If the lung: Cancer is advanced enough to cause those types of symptoms, a technically adequate contrast enhanced CT scan should have a detection sensitivity in the high 90s, probably approaching 100%. If the scan was technically limited or degraded by, say, artifact from patient motion, sensitivity could be significantly less. ...Read more
What can cause "equivocal edema and scalloping of the second duodenum" if h.Pylori and celiac are negative?
Wheat sensitivity: Could present many ways, abdominal bloating, pain, gas, diarrhea, rashes, aches, sinusitis, loss of tooth enamal, anemia, You can test for it by stoppping wheat products ,bread ,cookies cereals, for 10 days to a 2 weeks and seeing if there is a difference in symptoms. ...Read more
What is the most likely cause of protein and ketones in urine, egfr of 78%, negative cultures and normal blood results.
How much?: Miss a meal and you'll have +1 ketones in your urine. Many people have trace proteinuria and this is okay. You may also have orthostatic proteinuria caused by standing up -- some people are like this -- and this is easily ruled in or out by checking your first-voided urine in the morning. Forget "most likely"; you do need to have the cause found. Best wishes. ...Read more
Gastrin level 138, EGD showing small stomach inflammation, colonoscopy normal, . Lots of burning sensation, thirst, and ear ringing. What to testfor?
Talk to your GI: Gastrin of 138 is higher than expected normal but it's not severely high. It can be elevated due to just gastritis (inflammation of the stomach). The gastroenterologist likely tested for things while doing the EGD such as testing for h.pylori and taking biopsies. ...Read moreSee 1 more doctor answer
Is the consumption of milk and other dairy products correlated with the prevalence of prostate cancer?
No: While the cause of prostate is not known, and there are links to families with cancer, we next ascribe diet, mostly rish in saturated fats and red meats. Increasingly "healthy" diets are rich in fresh fruits and vegtables, lycopenes from processed tomatoes, elagic acid anti-oxidants from berries and cruciferous vegetables. Vitamin e appears not to help. Milk/dairy has not been indicted! ...Read moreSee 2 more doctor answers
I need to know how accurate is the schebo stool test in detecting colon cancer. Also can lack of fibre diet cause thin stools?
I have hashimoto s disease. But have had recent bloodwork done and the anti streptolysin o qual is positive and the CRP high sensitivity is 6.42.?
Lab results: Lab values seldom have significance unless correlated with clinical findings (history and physical, etc.) a qualitatively positive aslo titer has no real meaning other than you may have a strep infection previously. CRP is a very non-specific index of inflammation and without the above evaluation is of questionable value (may be due to hashimoto). Ask the doctor who ordered it. ...Read more
Ct shows large appendix. Blood tests negative for inflammation and infection. Can colonoscopy determine/see cause of pain in cecum/appendix area?
Sometimes large: Size is not the only criteria for appendicitis, Changes in mesentery and wall thickness. Another method of assessing appendix is ultrasound. If appendix localized inflammation in form of hyperemia is usually noted. Colonoscopy would not be method for assessment. Surgeons usually do not act with laparoscopy and surgery unless have some evidence clinically, blood tests, or imaging for appendiciitis ...Read moreSee 1 more doctor answer

Minority of patients can have tenderness even without acute diverticulitis. If pain is new/different, need to call ur pcp.

3 months left side abdo & flank pain and tenderness blood urine cystoscopy & CT scan fine. No diarrhea, but some constipation. Colonoscopy next. Cause?
Possibilities: A ct scan could have missed a kidney stone that passed just before the scan. It could also miss diverticulitis, depending on whether the ct scan was done with both IV and oral contrast. Colonoscopy is definitely the next thing to do. Another consideration is endometriosis, ovarian cyst, ectopic pregnancy, or inflammatory bowel disease. ...Read moreSee 1 more doctor answer
Perforation: The two main risks of colonoscopy are perforation and missed lesions. The national rate of perforation is 1 in every 3, 000 to 5, 000 colonoscopies. This is a very low rate, so much so that it is considered very low risk. The rate of missed lesions is estimated to be about 15 for every 100 lesions, nationally. The risk of sedation depends on your health status, but it is generally very safe. ...Read moreSee 1 more doctor answer

Can i go to a party after my colonoscopy? My procedure’s on friday morning and i want to go to a party that night. Is it safe for me to go? Can i drink?
Thanks : Thanks for your question. Generally we advise patients not to drive or operate any heavy machinery until the following day after a colonoscopy, because the medicines used to sedate you can cause cloudy thinking and altered judgment. There is no medical reason you couldn't go to a party if you are feeling up to it, but i would strongly suggest you go with a trusted friend who can drive you and stay with that friend for the duration of the party. Let him/her know that your judgment may be impaired so he/she can "look out" for you. I would suggest not drinking alcohol that night. I hope this answers your question. Good luck! ...Read moreSee 1 more doctor answer
Camera on a snake: A video camera on the end of a flexible stalk, not unlike a snake, is inserted through the rectum while you are asleep. You don't feel a thing, you won't remember it, and the only bed part is the prep. ...Read more
No: A colonoscopy is using a camera inserted into the rectum (under some level of sedation) through your colon to the cecum (area of the appendix) which allows us to look for cancer as well as to biopsy areas of abnormality. A UGI is an x-ray procedure where we use x-rays to take a picture of your esophagus and stomach with dye in it which allows us to look for leaks, blockages and other issues. ...Read moreSee 1 more doctor answer
Depends: It is recommended that a baseline screening colonoscopy be done about the age of 50 in those with no symptoms. People with a family history of colon cancer in close relatives should have one about 10-15 years before that relative was diagnosed with colon or rectal cancer. Patients with rectal bleeding or other symptoms should visit their doctor and discuss colonoscopy regardless of age. ...Read more
