The use of single-photon emission computed tomography and positron emission tomography (PET) has proven to be helpful in differentiating Parkinson's disease (PD) from other movement disorders with a sensitivity of up to 95%. ⋯ The [11C]DTBZ PET has an excellent accuracy for differentiating idiopathic PD from other disorders.

The prevalence of gastric polyps varies around the world reflecting regional associations. We describe demographic features of patients with gastric polyp diagnosis treated between 1980 and 2016 at a referral center in Mexico City and analyzed trends of polyp subtype. ⋯ The 1400% change of FGP explains the increased prevalence of gastric polyps. Chronic treatment with proton pump inhibitors and Helicobacter pylori eradication are possible explanations.

In colorectal cancer (CRC), regional lymphadenectomy provides prognostic information and guides management. The current consensus states that at least 12 lymph nodes (LN) should be evaluated. The aims of this study were to identify whether the number of LN is a predictor for survival and recurrence, and to reveal the role of LN ratio (LNR) and perineural invasion (PNI) in predicting prognosis after curative resection of CRC. ⋯ An LN retrieval < 10 increased local and distant recurrence rates. LNR was an independent prognostic factor for survival in Stage III tumors. PNI was the only significant independent prognostic factor affecting disease-free survival in our patients.

Pulmonary arterial hypertension (PAH) is a fatal complication in patients with connective tissue disease (CTD). ⋯ Patients with a partial response to the acute pulmonary vasodilator test with inhaled iloprost had a longer clinical deterioration-free period than non-responders.

In subjects without a history of coronary heart disease (CHD), type 2 diabetes mellitus (T2DM) is associated with carotid artery plaques (CAP), which is a better marker than high carotid intima-media thickness (hCIMT) for predicting first or recurrent cardiovascular events. ⋯ T2DM has an independent association with CAP. Early detection of recurrent cardiovascular events, with CAP identification, could be useful to prevent complications in patients with CHD.
