Don’t use brain SPECT (Single photon emission computed tomography) with DAT (dopamine transporter) radiopharmaceuticals in the differential diagnosis of degenerative Parkinsonisms or to convince a patient with Parkinson’s disease that he/she is really affected with that disease.

Don’t use brain SPECT (Single photon emission computed tomography) with DAT (dopamine transporter) radiopharmaceuticals in the differential diagnosis of degenerative Parkinsonisms or to convince a patient with Parkinson’s disease that he/she is really affected with that disease.

Although some papers in the literature have shown mild to moderate striatal uptake differences between the several forms of degenerative Parkinsonisms at group level, there is a considerable overlap at individual level and thus it is very unlikely that brain SPECT...
Do not prescribe abdominal ultrasound (or other imaging) follow-up for patients with asymptomatic hepatic hemangiomas smaller than 10 cm and without history of chronic liver disease.

Do not repeat esophagogastroduodenoscopy (EGD) in patients diagnosed with gastroesophageal reflux disease (GERD), unless the examination is part of the follow-up of precancerous epithelial conditions (Barrett’s esophagus) or in the event of new alarm symptoms.

Endoscopy in gastroesophageal reflux disease (GERD) should be reserved for patients who do not respond to an 8-week course of empirical therapy with proton pump inhibitors, for patients with extraesophageal symptoms that do not respond to therapy, for those presenting...
