The traditional melanoma staging system is not ideal for predicting patients' individual risk of disease recurrence and death. Subsequently, suboptimal adjuvant treatment may be offered. Hence, identification biomarkers to optimize stratification warranted. Cyclins cyclin-dependent kinase inhibitors, key players in the cell cycle regulation, are candidate prognostic biomarkers. Herein, their expression value studied. Cyclin D1, E, p16, p21, p27 were assessed using immunohistochemistry...

Abstract Background Although a larger proportion of colorectal surgeries have been performed laparoscopically in the last few years, steep learning curve prevents us from considering laparoscopic surgery as gold standard technique for treating disease entities colon and rectum. The purpose this single centre study was to determine, using various parameters following well-structured standardized surgical procedure, adequate number cases after which surgeon qualified open but with no previous...

Zuska's disease is a pathologic entity characterized by the formation of subareolar breast abscess caused obstruction lactiferous ducts. Although found relatively often in female patients, only 19 male cases have been reported. That makes diagnosis challenging males, leading to significant morbidity and high recurrence rates. Clinical evaluation imaging techniques, especially ultrasound mammography, are considered cornerstones for disease, whereas fine-needle aspiration cytology necessary...
