Prognostic value of chromosomal imbalances, gene mutations, and BAP1 expression in uveal melanoma.

Uveal melanoma (UM) exhibits recurring chromosomal abnormalities and gene driver mutations, which are related to tumor evolution/progression. Almost half of the patients with UM develop distant metastases, predominantly to the liver, and so far there are no effective adjuvant therapies. An accurate UM genetic profile could assess the individual patient's metastatic risk, and provide the basis to determine an individualized targeted therapeutic strategy for each UM patient.

Prevalence of oral human papillomavirus in men attending an Italian sexual health clinic.

A high-risk population, formed by 79 consecutive male attendees of our sexually transmissible infections clinic, and who did not have any overt signs of human papillomavirus (HPV) infection, were examined. Oral HPV prevalence (37%) was much higher than previously reported. Periurethral HPV-DNA was found in 49% of the patients and anal HPV-DNA was found in 43% of the patients.

Myenteric plexitis: A frequent feature in patients undergoing surgery for colonic diverticular disease.

Background: Diverticular disease of the colon is frequent in clinical practice, and a large number of patients each year undergo surgical procedures worldwide for their symptoms. Thus, there is a need for better knowledge of the basic pathophysiologic mechanisms of this disease entity.

Objectives: Because patients with colonic diverticular disease have been shown to display abnormalities of the enteric nervous system, we assessed the frequency of myenteric plexitis (i.

Lymph Node Metastasis from Tall-Cell Thyroid Cancer Negative on 18F-FDG PET/CT and Detected by 18F-Choline PET/CT.

A 77-year-old woman underwent thyroidectomy and (131)I remnant ablation for tall-cell differentiated cancer (DTC) of the left lobe. Detectable Tg levels (4.1 μg/L) under TSH suppression, with undetectable serum Tg-antibody levels, prompted neck ultrasonography, which revealed a lymph node in the left laterocervical region and in the right retroclavicular region.
