Case report of crusted scabies, brief review of its pathophysiology and latest data.

Background: Crusted scabies is a rare form of parasitic infection provoked by a massive infestation of the ectoparasite varietas hominis on human skin. It is an extremely contagious type of disease and can even lead to a social stigma. In European countries like Greece, many cases remain undiagnosed for long periods, causing extreme distress in the patient's everyday life and social environment.

Cathepsin D may help in discriminating node-negative breast cancer patients at risk for local-regional recurrence.

Objective: The objective of this retrospective study was to define the prognostic value of cathepsin D (CD) in the node-negative (N-) and node-positive (N+) subsets of breast cancer (BC) patients.

Patients And Methods: In primary tumor cytosols of 348, stage I-III, BC patients, with a complete standard histological examination and a 56 months mean follow-up, the ER, PR and CD concentrations were measured by standardized assays. CD values were then compared to the classical prognostic factors, the type of treatment and the outcome, in terms of Disease-Free-Survival (DFS) and type of Relapse, after stratification according to the nodal status.

Relationships between cathepsin-D, pS2 protein and hormonal receptors in breast cancer cytosols: inconsistency with their established prognostic significance.

In this study the unexpected findings from the analysis of 278 breast cancer tissue specimens are reported. A surprising strongly positive correlation between an unfavourable and a favourable prognosis with markers cathepsin D and pS2 respectively, was revealed by linear regression analysis (Pearson, Student-T-Test). In the relevant literature reviewed only one similar, although indirect, observation was found.

Cathepsin D concentration in tumor cytosols improves the accuracy of prognostic evaluation of primary breast cancer.

One hundred and seventy three women were followed-up for a median of 62 months after surgery for Stage I-III breast cancer. The concentration of cathepsin D (CD) in tumor cytosols was compared to the standard prognostic factors for the disease and related to relapse free and overall survival and type of relapse. Three groups were identified with different prognostic profile.
