An unusual case of a tibial metastasis as the first clinical presentation of a serous papillary carcinoma of the ovarian epithelial type of the testis.

Among testicular neoplasms, ovarian-type epithelial tumors constitute an exceedingly rare group, with only a few cases reported in the literature. We describe the case of an 82-year-old man, presented with complaints of right leg pain and difficulty walking, who was found to have a large right tibial metastasis of unknown primary origin. Whole body CT scan did not reveal any cranial, thoracic or abdominal tumor masses, but it showed abnormal para-aortic lymph nodes and right spermatic cord swelling.

Electrochemical Biosensors for Tracing Cyanotoxins in Food and Environmental Matrices.

The adoption of electrochemical principles to realize on-field analytical tools for detecting pollutants represents a great possibility for food safety and environmental applications. With respect to the existing transduction mechanisms, i.e.

Locally advanced rectal cancer: qualitative and quantitative evaluation of diffusion-weighted magnetic resonance imaging in restaging after neoadjuvant chemo-radiotherapy.

Purpose: To determine the added value of qualitative and quantitative evaluation of diffusion-weighted magnetic resonance imaging (DWI) in locally advanced rectal cancer (LARC) restaging after neoadjuvant chemo-radiotherapy (CRT).

Materials And Methods: A retrospective study was performed of 21 patients with LARC treated with CRT. All patients were evaluated with 1.

Biparametric MRI of the prostate.

Biparametric Magnetic Resonance Imaging (bpMRI) of the prostate combining both morphologic T2-weighted imaging (T2WI) and diffusion-weighted imaging (DWI) is emerging as an alternative to multiparametric MRI (mpMRI) to detect, to localize and to guide prostatic targeted biopsy in patients with suspicious prostate cancer (PCa). BpMRI overcomes some limitations of mpMRI such as the costs, the time required to perform the study, the use of gadolinium-based contrast agents and the lack of a guidance for management of score 3 lesions equivocal for significant PCa. In our experience the optimal and similar clinical results of the bpMRI in comparison to mpMRI are essentially related to the DWI that we consider the dominant sequence for detection suspicious PCa both in transition and in peripheral zone.
