Screening for advanced liver disease incorporating the use of transitional elastography in primary care.

Objectives: To describe the proportion of patients with liver fibrosis in at-risk populations in primary care (PC). To know the agreement between FIB-4 and transitional elastography (TE), interobserver agreement between PC and hospital care (HC) in TE, and associated risk Factors (RF).

Methods: Observational, descriptive, cross-sectional study in ≥16 years of age with RF for chronic liver disease.

[Ulcerative colitis associated with Vogt-Koyanagi-Harada disease].

We report the case of a female patient who was diagnosed with Vogt-Koyanagi-Harada disease at the age of 14 years and who developed myelopathy, resulting in paraparesis. A cerebral magnetic resonance imaging scan revealed the presence of T2-hyperintense lesions in the periventricular white matter, suggesting demyelinization. Twelve years later, ulcerative colitis was diagnosed during workup for abdominal pain associated with bloody diarrhea.

[Constitutional syndrome associated to metformin induced hepatotoxicity].

Metformin is an oral antidiabetic agent frequently used to manage type II diabetes. This drug produces nonspecific gastrointestinal symptoms in 5-20% of patients and, more rarely, has also been associated with severe adverse effects such as lactic acidosis. Only a few isolated cases of hepatotoxicity due to this drug have been documented.
