Background: Neuroendocrine Neoplasms (NEN) represent 60% of all appendicular tumours. This type of cancer is predominantly benign.  In this study, appendicular NEN tumours in children were investigated. Materials and Methods: This retrospective study was conducted on 540 patients underwent emergency appendectomy for the treatment of clinically suspected appendicitis at the department of p...

Introduction: Foreign-body aspiration is still considered one of the most important diagnostic and therapeutic issues for physicians. Mortality rates and the prevalence of diseases caused by foreign bodies in the airway are higher in children because of the relatively narrow airway and immature protective mechanisms. The aim of this study was to study the pattern of foreign-body aspiration in t...

Introduction: We present a retrospective two-center study series and discussion of the current literature to assess the benefits of facial nerve monitoring during parotidectomy. Materials and Methods: From 2007 to 2012, 128 parotidectomies were performed in 125 patients. Of these, 47 procedures were performed without facial nerve monitoring (group 1) and 81 with facial nerve monitoring (group 2...

A retrospective study has been made of all adult patients admitted to Manchester Royal Infirmary with exocrine pancreatic disease between 1968 and 1974, in order to define the factors which influence the variable mortality and morbidity rates in published accounts of patients with acute pancreatitis. The most plausible explanation is that some series with low mortality rates include a variable ...

Objective: In contrast to humans, neutrophil myeloperoxidase deficiency (MPOD) has been rarely investigated in dogs. The hematology analyzer ADVIA®120 differentiates leukocytes based on the cellular volume and their myeloperoxidase concentration. The aim of this study was the characterization of myeloperoxidase deficiency in dogs and the evaluation of the diagnostic use of the ADVIA®120 Myelope...
