This article describes the development of a free/open-source rule-based machine translation system for Catalan to Sardinian based on the Apertium platform. Special attention is given to the components of the system related with transfer (structural and lexical) and lexical selection, drawing attention to issues stemming from the current state of the Sardinian written norm. The system has a word-error rate (WER) of 20.5% and a position-independent word-error rate (PER) of 13.9%. We analyse the remaining errors by doing a qualitative analysis of the translation of four articles from the encyclopaedic domain.

The differences between the 12 million refugees and theestimated 25 million internally displaced persons (IDPs)around the world, as far as the international community isconcerned, is that the former have crossed internationalborders while the latter have remained within their countries.

The need for international standards to protect andassist internally displaced persons arose directlyfrom the explosion of civil wars in the last decade ofthe 20th century that left tens of millions uprootedwithin the borders of their own countries.

The rebellion in Darfur cannot be viewed in isolation from events elsewhere in Sudan.

Although I have received generous praise over the yearsfor my efforts on behalf of the world’s internally displacedpersons as representative of the UN Secretary-Generalon the issue, I say, without hesitation, that withoutRoberta Cohen I could not have done what I did.

Entre los problemas más urgentes que tiene la medicina, sin duda alguna está el problema de la epilepsia. Muchas son las personas que sufren una forma u otra de este azote. Estadísticamente se asegura que una de cada 200 personas presenta convulsiones. Además, se trata de una enfermedad crónica que dura de por vida, sin que aparentemente influya en la longevidad de quien sufre de ataques. No se trata de una enfermedad con importancia estadística solamente, sino que también es un problema con que el médico tropieza día tras día. Es sólo natural que algunos médicos se hayan interesado en este problema. Últimamente se han dado grandes pasos en el adelanto y la comprensión de las causas de la epilepsia.

Crohn's disease is rare in Mexico. The regarding of this pathology at Gastrointestinal Unit of the General Hospital of Mexico city, between january 1980 and december 1989, is presented. There were six cases of Crohn's disease, two women (33%) and four men (66%). The definitive diagnosis was done preoperatively only in one case, the other were diagnosed postoperatively. In all, intestinal obstruction was the surgical indication. A patient died (16.6%), three cases were followed for 12 months, only two patients are still under surveillance after 15 months.

We present two years of our surgical experience in the Gastroenterologic department of General Hospital of Mexico city; we studied prospectively 23 patients with choledocholithiasis diagnosed preoperatively and postoperatively, 18 females (78%) and 5 males (22%). Diagnosis were performed preoperatively by sonogram, intravenous cholangiography and/or endoscopic retrograde pancreatocholangiography in 19 cases, and postoperatively in four cases. In 22 cases we performed colecistectomy with choledocotomy, extraction of calculi and placement of a "T" biliary catheter. In only one case was necessary a choledoco-duodenal anastomosis. We observed morbility in 3 cases (13%), and a patient died postoperatively (4%). The postoperative follow up was satisfactory in 83% of these cases.
