Effects of in-hospital exercise on liver function, physical ability, and muscle mass during treatment of hepatoma in patients with chronic liver disease.

Aims: Sarcopenia and physical disability assessed by a 6-min walking test (6MWT) are associated with poor prognosis of patients with chronic liver disease (CLD). However, CLD patients with hepatocellular carcinoma (HCC) mostly rest in bed during hospitalization. We aimed to investigate the effects of therapeutic exercise on liver function, 6MWT, and skeletal muscle mass during HCC treatment in patients with CLD.

Melanocytic nevi clinically simulating melanoma.

Melanoma and other benign or malignant pigmented skin tumors can significantly overlap in their clinical and dermoscopical presentations. Thus, pigmented skin lesions may be misdiagnosed in a large number of cases. An extensive review of the published work provides numerous examples of benign lesions mimicking melanoma.
