Assessment of Agriculture Pressures Impact on the Joumine River Water Quality Using the PEGASE Model.

The protection of the aquatic environment while managing the risk of water scarcity in the Mediterranean region is challenging. Ensuring future sustainability of water resources needs improved monitoring networks and early warning system of future trends of water quality. A specific concern is given to nonpoint source pollution from agriculture, which is often the main source of water quality degradation in rivers.

Long-term follow up of post-surgical tooth autotransplantation: a retrospective study.

Aim: The aim of the present retrospective study was to evaluate the long-term results of tooth autotransplantation using the survival and success rates of transplanted teeth as outcome variables.

Methods: Thirty patients received a total of 44 transplants of immature teeth from 1987 to 1997. Seventeen of those patients with 25 transplants were recalled 10-20 years after tooth transplantation for complete clinical and radiographic examinations, followed by questionnaires that examined the patients' degrees of satisfaction.

Comparative analysis of primary repair vs resection and anastomosis, with laparostomy, in management of typhoid intestinal perforation: results of a rural hospital in northwestern Benin.

Background: The objective is to compare primary repair vs intestinal resection in cases of intestinal typhoid perforations. In addition, we hypothesised the usefulness of laparostomy for the early diagnosis and treatment of complications.

Methods: 111 patients with acute peritonitis underwent emergency laparotomy: number of perforations, distance of perforations from the ileocaecal valve, and type of surgery performed were recorded.

AFM force spectroscopy of the fibrinogen adsorption process onto dental implants.

Protein binding to implants is governed by the physicochemical properties of the biomaterial surface. The adhesion of a protein onto a solid surface is nonspecific. The aim of this study was to assess the adsorption process of fibrinogen at two different dental implants.

Anaphylactic shock during endodontic treatment due to allergy to formaldehyde in a root canal sealant.

A 41-yr-old patient experienced an anaphylactic shock reaction caused by formaldehyde in a root canal sealant during endodontic treatment. The clinical events, positive skin tests, and a high level of immunoglobin E to formalin RAST (class 4) suggest the involvement of immunoglobin E-dependent mechanisms toward formaldehyde. This very infrequent observation in endodontic therapy focuses attention on the different pathological manifestations related to formalin, their mechanisms, and the prevention possibilities in dentistry.
