differential diagnosis example

To perform a differential diagnosis, the physician starts by reviewing the patient's case. Cocaine-induced lung … A diagnosis of major depressive disorder can be made if the symptoms are severe enough to interfere with a person’s ability to sleep, study, eat and enjoy life (NIMH, 2015). Besides, it is caused by hypersensitivity to irritants like fumes, dust, and smoke (Stacy Sampson, 2019). Influenza. Such a constellation can be estimated to have a sensitivity of approximately 70% and a specificity of approximately 90% for primary hyperparathyroidism. Problems of a serious nature include, but are not limited to, visceral diseases, cancer, infections, fractures, and vascular disorders. With updated probabilities for each of the candidate conditions, the indications for further tests, treatments or other actions changes as well, and so the procedure can be repeated until an end point where there no longer is any indication for currently performing further actions. @Cupcake15 - I think that that is the hardest part of medicine because you have to do a lot of research and even though you have a lot of information, you still may not know what the patient has which has to be really disheartening. Its probability in the population (P(No abnormality in population)) is complementary to the sum of probabilities of "abnormal" candidate conditions. What does an Infectious Disease Specialist do. Such an end point mainly occurs when one candidate condition becomes so certain that no test can be found that is powerful enough to change the relative probability-profile enough to motivate any change in further actions. Your doctor must differentiate between these to determine the actual diagnosis and appropriate treatment plan. Hypersensitivity pneumonia. De très nombreux exemples de phrases traduites contenant "differential diagnosis" – Dictionnaire français-anglais et moteur de recherche de traductions françaises. Examples of differential diagnosis It is important to consider human orf in the differential diagnosis of hand lesions to prevent overtreatment and complications. The probability of primary hyperparathyroidism is now termed Pre-BTPH because it corresponds to before the blood test (Latin preposition prae means before). Unfortunately, there are currently no lab tests to identify depression. It was eventually discovered that the little girl had a very rare disease that did not allow her blood to clot correctly which is why with the littlest scratch she would make her bleed. Differential Diagnosis II: GRIEF [8] This confers a likelihood ratio positive of 7 for primary hyperparathyroidism. Prioritize the list by placing the most urg… The patients all had progressively worsening conditions, but the doctors continually misdiagnosed the problems and only after the patients sought renowned specialists did they get an accurate medical differential diagnosis. Regardless of the topic, subject or complexity, we can help you write any paper! This is an indication for considering a combination of primary hyperparathyroidism and cancer, such as, in this case, a parathyroid hormone-producing parathyroid carcinoma. For "cancer", the cutoff at which to confidently regard it as ruled out may be more stringent because of severe consequences of missing it, so the physician may consider that at least a histopathologic examination of the resected tissue is indicated. Throughout the series, the doctors have diagnosed such diseases as mastocytosis, Plummer's disease, rabies, Kawasaki's syndrome, smallpox, Rickettsialpox, and dozens of others. He is taking a “water pill” and is not allergic to any medications. This example case demonstrates how this method is applied, but does not represent a guideline for handling similar real-world cases. Radiation pneumonitis. For example, an abdominal pain differential diagnosis should also consider if there is any bleeding associated with the pain which could mean that the patient may have an ulcer or may have something as serious as cancer. It often involves several tests. In a particularly puzzling case, the doctor might interview friends and coworkers or examine the patient's natural environment to look for causes. Developing a comprehensive list of differential diagnosis is a key step in the diagnostic approach of patients with neurologic problems. Multiplying with likelihood ratios necessitates conversion of likelihoods from probabilities to odds in favor (hereafter simply termed "odds") by: However, only the candidate conditions with known likelihood ratio need this conversion. Later, when the situation is less acute, a more comprehensive differential diagnostic procedure may be adopted. Not every health disorder can be diagnosed with a simple lab test. With the likelihood ratio positive of 7 for the blood test, the post-test odds is calculated as: An Odds(PostBTPH) of 4.16 is again converted to the corresponding probability by: The sum of the probabilities for the rest of the candidate conditions should therefore be: Before the blood test for parathyroid hormone, the sum of their probabilities were: Therefore, to conform to a sum of 100% for all candidate conditions, each of the other candidates must be multiplied by a correcting factor: For example, the probability of cancer after the test is calculated as: The probabilities for each candidate conditions before and after the blood test are given in following table: These "new" percentages, including a profile-relative probability of 80% for primary hyperparathyroidism, underlie any indications for further tests, treatments or other actions. Musculoskeletal: These conditions relate to … Many conditions cause similar symptoms. A recalculation may therefore be needed, with the first two conditions being separated into "primary hyperparathyroidism without cancer", "cancer without primary hyperparathyroidism" as well as "combined primary hyperparathyroidism and cancer", and likelihood ratios being applied to each condition separately. Many studies demonstrate improvement of quality of care and reduction of medical errors by using such decision support systems. This paper considers three examples of potential diagnoses for this condition with an explanation of why such a diagnosis might be appropriate if other symptoms apply. Acute bronchitis. It was estimated at 37.3%, corresponding to an odds of 0.595. At this point, the probability of "other conditions" is so low that the physician cannot think of any test for them that could make a difference that would be substantial enough to form an indication for such a test, and the physician thereby practically regards "other conditions" as ruled out, in this case not primarily by any specific test for such other conditions that were negative, but rather by the absence of positive tests so far. However, these tools all still require advanced medical skills to rate symptoms and choose additional tests to deduce the probabilities of different diagnoses. Differential diagnostic procedures are used by physicians to diagnose the specific disease in a patient, or, at least, to eliminate any imminently life-threatening conditions. Many studies demonstrate improvement of quality of care and reduction of medical errors by using such decision support systems.
