A novel hydrogeochemical approach to delineate the origin of potentially toxic elements in groundwater: Sophisticated molar ratios as environmental tracers.

The occurrence, mobilization, and origin of Potentially Toxic Eelements (PTEs) in the environment is always a difficult research question that has not been fully addressed to date; solving this problem would be a major achievement for environmental science and pollution research, a significant scientific breakthrough, and an important contribution to environmental analysis and monitoring. The lack of a holistic methodology that uses chemical analysis to determine the origin of each PTE in the environment is the main motivation for this project. Therefore, the hypothesis tested here is to develop a scientific approach applied to each PTE to determine whether its origin is geogenic (i.

Late complication following percutaneous cholecystostomy: retained abdominal wall gallstone.

A case of recurrent abdominal wall abscess following percutaneous cholecystostomy (PC) is presented. Transperitoneal PC was performed in an 82-year-old female with calculous cholecystitis. Symptoms resolved and the catheter was removed 29 days later.

Core mental state in irritable bowel syndrome.

Objective: Psychiatric illness is higher among patients with irritable bowel syndrome (IBS) who seek medical care; however, a specific psychopathology that differentiates patients with IBS from patients with other organic gastrointestinal disorders has not been found. In the study described here, we investigated the predominant psychiatric symptoms in women with IBS.

Methods: The criteria of Manning et al.

Acquired inhibitors to the coagulation factor XII associated with liver disease.

Three patients with liver disease and prolonged activated partial thromboplastine time (APTT) on routine tests are presented. One woman had metastatic liver disease from gastric carcinoma, a second woman had autoimmune hepatitis, and one man had severe chronic hepatitis B. APTT was not corrected after mixing experiments with 25%, 50%, and 75% of normal pool plasma, indicating the presence of an acquired inhibitor.

Maturation of the tract after percutaneous cholecystostomy with regard to the access route.

Purpose: To assess the shortest time for catheter removal with regard to the transhepatic or transperitoneal approach in patients undergoing percutaneous cholecystostomy (PC).

Methods: In this prospective study, 40 consecutive high-risk patients with acute cholecystitis (calculous, n = 22; acalculous, n = 18) underwent PC by means of a transhepatic (n = 20) or transperitoneal (n = 20) access route. In 28 patients (70%) computed tomography was used for puncture guidance, while in the remaining 12 (30%) the procedures were formed under ultrasound control.
