The Morra Game as a Naturalistic Test Bed for Investigating Automatic and Voluntary Processes in Random Sequence Generation.

Morra is a 3,000-years-old hand game of prediction and numbers. The two players reveal their hand simultaneously, presenting a number of fingers between 1 and 5, while calling out a number between 2 and 10. Any player who successfully guesses the summation of fingers revealed by both players scores a point.

The importance of tissue damage secondary to high voltage electrical injury to the limbs often makes the management of this kind of burn very difficult. Repair interventions are sometimes ineffective and amputations are then unavoidable. We report the case of a young patient suffering electrical injury to both upper limbs caused by a high voltage current, whose evolution was dramatically marked by bilateral disarticulation of both shoulders.

Clinicopathological differences of colorectal cancers according to tumor origin: Identification of possibly lesions.

Colorectal cancer (CRC) is considered to develop through the conventional adenoma-carcinoma sequence. However, the existence of carcinogenesis, without any intervening precursor lesions, has been suggested for certain morphologically different tumors lacking polypoid characteristics. The presence of such tumors, along with their correlation with cardinal clinicopathological parameters, such as stage, grade and site, was retrospectively investigated in a series of 119 surgically treated CRC cases.

The pattern of epidermal growth factor receptor variation with disease progression and aggressiveness in colorectal cancer depends on tumor location.

The role of epidermal growth factor receptor (EGFR) in colorectal cancer (CRC) prognosis remains unclear despite the recent development of anti-EGFR treatments for metastatic disease. The heterogeneity of CRC may account for this discrepancy; proximal and distal CRC has been found to be genetically and clinicopathologically different. The aim of this study was to investigate the effect of tumor location on the association of EGFR with the conventional prognostic indicators (stage and grade) in CRC.

Worse histological grade of proximal colorectal tumors and its relation with stage.

Purpose: Accumulated data seem to support the concept that proximal and distal colorectal cancers (CRC) should be considered as different disease entities. We investigated a particular aspect of this assumption by examining variation of stage and grade distribution according to tumor site in a Greek patients' group.

Methods: A total of 200 cases having had undergone surgery for primary CRC was retrospectively analysed.
