Homomorphic Adenocarcinoma Metastases to the Liver: A Report of 2 Cases.

BACKGROUND Distinguishing between primary and metastatic malignancy can be challenging despite advances in diagnostic imaging, tissue sampling techniques, and immunohistochemistry. CASE REPORT Herein, we describe 2 cases of obscure liver lesions which were ultimately determined to be malignant and from metastatic disease. In both cases, the liver metastases were uniquely "homomorphic," i.

Comparative effectiveness of aggressive intravenous fluid resuscitation with lactated Ringer's solution and rectal indomethacin therapy in the prevention of pancreatitis after endoscopic retrograde cholangiopancreatography: a double blind randomised controlled clinical trial.

Introduction: There is growing evidence indicating the aggressive intravenous fluid resuscitation (IVFR) can decrease the rate of pancreatitis; however, to the best of our knowledge it has not been well studied in a post-endoscopic retrograde cholangiopancreatography (post-ERCP) setting.

Aim: To compare the effects of aggressive IVFR and rectal indomethacin (RI) in preventing pancreatitis after ERCP.

Material And Methods: This is a double blind randomised controlled clinical trial on 186 patients undergoing ERCP in Ahvaz, Iran.

A correlation study of diagnostic fine-needle aspiration with histologic diagnosis in cystic neck lesions.

The clinical diagnosis of a mass in the neck region encompasses a wide spectrum of differential diagnosis. Fine-needle aspiration is a quick and safe technique, which can provide useful information for initial assessment and further therapeutic measures. The aim of this retrospective study was to evaluate the performance characteristics of the fine-needle aspiration (FNA) in cystic neck lesions.

Noninvasive monitoring of the autonomic nervous system and hemodynamics of patients with blunt and penetrating trauma.

Background: To describe early effects of sympathetic (SNS) and parasympathetic nervous system (PSNS) activities measured by heart rate (HR) and respiratory rate variabilities simultaneously with noninvasive hemodynamic patterns in patients with blunt and penetrating trauma.

Methods: Descriptive study of 168 monitored trauma patients in a level I university-run trauma service. We studied HR and respiratory rate variability by spectral analysis as a measure of autonomic nervous system (ANS) activity in severe blunt and penetrating injuries beginning shortly after their admission to the emergency department.

Autonomic activity in trauma patients based on variability of heart rate and respiratory rate.

Objective: To evaluate the effects of sympathetic and parasympathetic nervous system activity on the heart rate and other hemodynamic variables in acute emergency patients with mild to moderately severe trauma.

Design: Clinical study.

Setting: Level 1 university-run trauma service.
