ABSTRACT
BACKGROUND AND STUDY AIMS: Helicobacter pylori is the main cause of gastritis, gastroduodenal ulcers and gastric cancer. In the past two decades, the recommended treatment for its eradication as a first-line regimen is the standard triple therapy consisting of a proton pump inhibitor (PPI), amoxicillin and clarithromycin or metronidazole. However, the effectiveness of this traditional regime, which initially was 90%, progressively declined in many parts of the world and is currently 57-73%. The aim of this study was to evaluate whether the eradication rate with triple therapy with levofloxacin is superior as first-line therapy to that with treatment using clarithromycin in the population that attended as outpatients at the Hospital of Lídice. PATIENTS AND METHODS: We designed a prospective study, with two groups of patients presenting dyspeptic symptoms, from October 2010 to October 2011, who underwent upper gastrointestinal endoscopy and whose biopsies were positive for infection with H. pylori. At the end, 81 patients were included in the order of biopsy result arrival to fill the quota of each group. The first group with 42 patients underwent triple therapy with clarithromycin and the second group with 39 patients underwent therapy with levofloxacin, amoxicillin and a PPI. The patients' age ranged between 23 and 76years, the average being 49.5. The predominant sex was female, at 72.84%. Both treatments lasted for 10days and the patients were clinically re-evaluated 15days after their conclusion and programmed for a second endoscopy to verify H. pylori eradication. RESULTS: Among the 42 patients in the control group, there were 14 eradication failures with 33.33% resistance to clarithromycin. Among the 39 patients in the experimental group, two eradication failures with 5.13% resistance to levofloxacin were observed. The χ(2) value was 6.96. CONCLUSIONS: Treatment with levofloxacin was more effective than conventional triple therapy. Triple therapy with levofloxacin can be implemented in populations where resistance to clarithromycin has been observed.

La clasificación de Child-Pugh mide la severidad de la enfermedad hepática crónica en pacientes con cirrosis hepática. El nivel de sodio (Na) sérico en estos pacientes disminuye a medida que progresa la enfermedad hepática. Objetivo: determinar la relación de la severidad de la enfermedad hepática crónica medida con la escala de Child-Pugh, con el nivel de sodio sérico. Metodología: se realizó un estudio retrospectivo descriptivo, analizando las historias clínicas de los pacientes evaluados en las consultas externas y hospitalizados en el servicio de Gastroenterología del Hospital "Jesús Yerena" de Lídice entre los años 2002 y 2006. Se calculó el puntaje de Child-Pugh a cada paciente, y luego se relacionó con los valores séricos de Na. Resultados: se hallaron 12 pacientes (24,49%) en la categoría Child- Pugh A, 21 (42,86%) clase B, y 16 (32,65%) clase C. Se encontró una relación inversa en cuanto al nivel sérico de Na y el puntaje de Child-Pugh. Conclusión: La severidad de la enfermedad hepática crónica, medida por la escala Child-Pugh, es inversamente proporcional con en nivel de Na sérico de estos paciente.
The Child-Pugh classification assesses the severity of chronic hepatic disease in patients with hepatic cirrhosis. Serum sodium level in these patients decreases along with the severity of the hepatic disease. Objective: to determine the relationship between the severity of chronic hepatic disease, measured with the Child-Pugh scale, and serum sodium levels. Methods: we made a retrospective descriptive study, analyzing the clinical history of outpatients and hospitalized patients of the Gastroenterology Service of "Jesús Yerena Hospital of Lidice" between 2002 and 2006. We calculated the Child-Pugh scale of each patient, and then correlated it to serum sodium levels. Results: we found 12 patients (24, 49%) in the Child- Pugh A category, 21 (42, 86%) in the class B category, and 16 (32, 65%) in the class C category. They all had an inverse relationship with serum sodium levels. Conclusion: the severity of chronic hepatic disease, measured in the Child-Pugh scale, is inversely proportional to the serum sodium level in these patients.
ABSTRACT
Neste trabalho testamos clinicamente 6 tratamentos para remineralização de cáries incipientes em crianças de 7 a 15 anos e de ambos os sexos. Também estabelecemos alguns critérios básicos para o diagnóstico e a avaliação clínica das lesões. Os resultados estatísticos comprovaram a eficácia dos tratamentos com 8 semanas de aplicação
