Whether and to what extent the pancreas is involved in acute viral hepatitis is still unclear. In order to address this issue we evaluated serum and urinary amylase and isoamylase levels in 92 ...patients with acute viral hepatitis of different etiology and in 60 healthy volunteers. Furthermore, pancreatic structure and volume were evaluated by ultrasound scanning. Significant increase in serum and urinary pancreatic isoamylases was found in 12 and 35% of patients, respectively, in the early stage of the disease. Increase in serum pancreatic isoamylases was found only in patients suffering from B and non-A, non-B hepatitis. Ultrasonographic evaluation did not show any change in pancreatic structure and volume. In conclusion, this study suggests that mild pancreatic damage may occur during viral hepatitis.
Evaluar el consumo de paracetamol, metamizol y ácido acetilsalicílico (AAS) en un estudio multicéntrico.
Pacientes y método: Se analizaron los controles de un estudio de casos y controles ...hospitalarios (n = 1.029) sobre cáncer vesical mediante la aplicación de una matriz de medicamentos y principios activos. El motivo de ingreso de los controles no se asociaba con el uso crónico de analgésicos. Se utilizó un modelo de regresión logística.
El uso crónico de AAS fue del 8%, el de paracetamol, del 5% y el de metamizol, del 2%. El AAS fue más usado por personas con educación secundaria o superior (
odds ratio OR
=
2,0, intervalo de confianza IC del 95%, 1,52-2,93). Las mujeres usaron más paracetamol (OR
=
1,91; IC del 95%, 1,30-2,80) y metamizol (OR
=
2,80; IC del 95%, 1,49-4,47). Los menores de 65 años usaron más metamizol.
El uso crónico de AAS y paracetamol es bajo comparado con el de Estados Unidos o el norte de Europa, aunque es parecido al del sur de Europa. Hay diferencias en el uso de analgésicos en función de las variables sociodemográficas.
To evaluate the use of acetaminophen (paracetamol), aspirin and dipyrone (metamizol) in a multicenter study.
We analyzed the controls of a hospitalbased case-control study (n
=
1029) of bladder cancer using a matrix of drugs and active principles. The admission diagnosis of the study controls was not associated with chronic analgesic use. A logistic regression model was used.
Eight percent of the controls were regular users of aspirin, 5% regularly used acetaminophen and 2% regularly used dipyrone. Aspirin was more frequently used by subjects with at least secondary education (OR
=
2.0; 95% CI, 1.52-2.93). Women more frequently used acetaminophen (OR
=
1.91; 95% CI, 1.30-2.80) and dipyrone (OR
=
2.80; 95% CI, 1.49-4.47). Subjects under 65 years old more frequently used dipyrone.
Chronic use of aspirin and acetaminophen is lower than that reported in North America or northern Europe and is similar to that seen in southern Europe. Differences in the pattern of analgesic use were found among sociodemographic population groups.
The combination of 5-fluorouracil (5-FU) plus leucovorin (LV) with oxaliplatin has become one of the standard treatments for advanced colorectal cancer (CRC). Two consecutive phase II trials assessed ...the efficacy and safety of combined therapy with oxaliplatin and high-dose 5-FU without LV for patients with advanced CRC. A total of 89 patients were enrolled in both trials. Fifty-nine patients in trial A underwent a scheduled regimen of biweekly oxaliplatin 85 mg/m
2 and weekly nonmodulated 5-FU 3.0 g/m
2. Increased incidence of toxicity led to a 25% reduction in the starting dose of 5-FU (2.25 g/m
2) for trial B. Patients treated in trial B showed a higher cumulative dose and relative dose intensity for oxaliplatin and 5-FU than those treated in trial A. Response to treatment, time to progression (TTP), overall survival (OS), and duration of response were evaluated as efficacy variables. Overall response rate was preserved despite the reduction in 5-FU dose (55.9% and 63.0%, respectively). Median durations of responses were 10.6 and 10.4 months, median TTPs were 7.7 and 7.3 months, and OS times were 21.7 and 13.1 months, respectively. Reduction in the starting 5-FU dose from 3.0 to 2.25 g/m
2 resulted in a decrease in the main grade 3/4 hematologic toxicities (neutropenia, 22.0% to 10.0%) and nonhematologic toxicities (diarrhea, 52.5% to 23.3%; nausea/vomiting, 18.6% to 3.3%). Neurosensory toxicity was similar in both trials (16.9% and 16.7%). Biweekly oxaliplatin in combination with nonmodulated high-dose 5-FU is an active, well-tolerated treatment that offers a lower cost than a modulated schedule for patients with advanced, metastatic CRC.
