Association between tumor-infiltrating lymphocytes and sentinel lymph node positivity in thin melanoma.

Background: Sentinel lymph node biopsy in thin invasive primary cutaneous melanoma (up to 1mm thick) is a controversial subject. The presence of tumor-infiltrating lymphocytes could be a factor to be considered in the decision to perform this procedure.

Objective: To evaluate the association between the presence of tumor-infiltrating lymphocytes and lymph node metastases caused by thin primary cutaneous melanoma.

Association between trochanteric bursitis, osteoarthrosis and total hip arthroplasty.

Objective: this was an epidemiological study on trochanteric bursitis at the time of performing total hip arthroplasty.

Methods: sixty-two sequential patients who underwent total hip arthroplasty due to osteoarthrosis, without any previous history of trochanteric bursitis, were evaluated. The bursas were collected and evaluated histologically.
