BACKGROUND: Current management of malignant obstruction of the upper digestive tract includes surgical gastrointestinal bypass or endoscopic insertion of self-expandable metal stents. The safety, efficacy, and long-term patency rates of anastomoses created using the novel technique of endoscopic gastroenteric anastomosis using magnets (EGAM) are evaluated in this study. PATIENTS AND METHODS: 15 patients (13 men, 2 women; mean age 64.5 years) with malignant obstruction, who underwent EGAM and had monthly follow-up between December 2001 and May 2003, were included in this study. RESULTS: The procedure was successful in 13 patients (88.66 %). The mean survival was 5.23 months. There were four minor complications (30.76 %) during the follow-up period. CONCLUSION: Our results demonstrate the feasibility, safety. and efficacy of this technique for creating a gastroenteric anastomosis. The success rate was 86.6 %, there were no immediate complications, and there was no mortality related to the procedure.

INTRODUCTION: Endoscopic sphincterotomy (ES) is commonly used to remove bile-duct stones and to treat other problems. We prospectively investigated complications and mortality of endoscopic retrograde cholangiopancreatography (ERCP). 2. PATIENTS AND METHODS: Between june 6, 1998 and june 6, 1999 553 ERCP were performed in our centers. Inclusion criteria for protocol were: ERCP indication, complete follow-up and informed consent. We prospectively studied complications of ECRP in consecutive patients treated at 2 institutions (San Martin Hospital, La Plata, Argentina and Hadassah University Hospital, Jerusalem, Israel). The follow-up was done during 365 days with a clinical examination, laboratory test and ultrasonography to determine the possible complications. 3. RESULTS: Of 553 ERCP, 43 had a complications; including pancreatitis in 16 cases, cholangitis in 12, hemorrhage in 5, perforation in 3 and miscellaneous in 7. 3-1) ES frequency: 241 patients (pts). 3-2) Follow-up: 365 days in 504 pts. 3-3) Sex and age: women 274 pts, men 230 pts. Age range 1 month to 90 year old. 3-4) Final diagnoses: choledocholitiasis (38.8%), strictures (18%), pancreatic cancer (4.3%), ampullary cancer (2.3%) and normal ERCP (24.4%). 4. CONCLUSIONS: The rate of complications after ES can vary in different circumstances and is primarily related to the indication for the procedure and to endoscopic technique. Our percentage of complications (7.53%) coincide with consulted studies. Today, diagnostic ERCP has been challenged by magnetic resonance cholangiography (MRC). MRC provides images of the billary and pancreatic ducts that are nearly equal to those of ERCP without the procedural risk associated.

RESUMO
La osteonecrosis abarca un amplio campo de enfermedades de etiología multifactorial que se inicia en el árbol vascular nutriente del cartílago y la matriz ósea. Las fases finales se caracterizan por su carácter avascular y, por tanto, de desvitalización del tejido óseo. La clínica se caracteriza por dolor e impotencia funcional creciente, y el tratamiento depende de la fase de la enfermedad en el momento de la detección y del grado de afectación ósea. Se presentan dos casos, con circunstancias y tratamientos diferentes (AU)

A pesar de su escasa frecuencia, la incidencía de traumatismos mamarios ha aumentado en relación directa con el número global de accidentes laborales y con la creciente participación de la mujer en actividades de trabajo. Los traumatismos mamarios adquieren en esta población una mayor importancia debido a la considerable proporción que la mama representa en la superficie torácica y a la posición expuesta y características peculiares de estos órganos. Presentamos cuatro casos de traumatismo mamario como accidente laboral, tres de ellos debidos a traumatismos mamarios directos y el cuarto en el contexto de un accidente in itinere, y describimos los hallazgos más significativos (AU)

OBJECTIVE: Chromosome instability provides a predisposing background to malignancy, contributing to the crucial genetic changes in multistep carcinogenesis. The aim of this work was to analyze chromosome instability in patients with ulcerative colitis (UC) to achieve a better understanding of the increased risk for colorectal cancer. METHODS: Peripheral blood lymphocyte cultures from 20 untreated UC patients and 24 controls were used to study chromosome instability by assessing telomeric associations (TAS), chromosome aberrations (CA), and sister chromatid exchanges (SCE). RESULTS: Mean frequencies of TAS and CA were significantly increased in UC patients compared to controls (p < 0.001). Chromosomes 10, 11, 21, 16, and 19 were the most frequently involved in TAS. A total of 104 CA clustered in 66 breakpoints could be exactly localized. Seven nonrandom bands significantly affected in UC patients were found (p < 0.004), showing a significant correlation with the location of cancer breakpoints (p < 0.003), particularly with colorectal carcinoma rearrangements. SCE analysis showed higher levels in patients compared to controls (p < 0.006), but no differences were observed in cell cycle kinetics. CONCLUSIONS: Our results demonstrate the presence of an unstable genome in UC patients that could be related to the cancer development observed in this disease.

A case-control study has been conducted to investigate the relationship between total energy intake, fibre and nutrients and colon cancer in Argentina. Cases are 110 newly diagnosed patients from 10 hospitals between 1985 and 1986. Two neighbourhood controls per case were matched on age, sex and place of residence. The intake of calories, fibre and nutrients was estimated from the information collected on food consumption during the 5-year period up to 6 months prior to interview of subjects, based on a pilot study and standard portion sizes in Argentina. In conditional regression models, dietary fibre is highly protective (odds ratio (OR) = 0.07 per 19.02 g/day; 95% confidence interval (CI): 0.02 to 0.25) and total energy intake increases risk (RR = 1.82 per 1000 kcal/day; 95% CI: 1.20 to 2.77), each with adjustment for the other. Analysis of caloric components (fat, protein and carbohydrates) reveals that carbohydrates are the most important factor driving the total energy effect. Other nutrients make little apparent contribution to risk.

A case-control study has been conducted to investigate the relationship between dietary components and risk of colon cancer in the La Plata area of Argentina. Cases are 110 patients newly diagnosed with colon cancer in 10 major hospitals between 1985 and 1986. Two neighbourhood controls per case were individually matched by age, sex and place of residence. Personal interviews elicited information on frequency of consumption of 140 food items during the 5-year period up to 6 months prior to interview. Risk is analyzed by quartiles of individual food items and groups of items. Multivariate conditional logistic regression modelling indicates that consumption of eggs is associated with increased risk for colon cancer (odds ratios by quartile: 1.0, 1.58, 2.02, 4.66), as are some dairy products (ORs of 1.93 for the highest quartile of consumption of cheese). Intake of vegetables, fish and poultry is associated with statistically significant decreasing risk (ORs of 0.075, 0.39 and 0.39, for the highest categories of consumption of vegetables, fish and poultry, respectively). The risk for red meat does not consistently increase as consumption increases. Risks are not altered by the inclusion of potential confounders such as education or body mass index. These findings confirm those of several previous studies and are of particular interest, since the Argentinean diet typically includes a high intake of red meat.
