CONCLUSIONS: Although the trials have shown efficacy of LOLA in reducing hyperammonemia of hepatic encephalopathy, sufficient evidence of a significant beneficial effect of LOLA on patients with hepatic encephalopathy was not found. The studies performed in this area were small, with short follow-up periods and half of them showed low methodological quality.CONTEXTO: Estudos experimentais e clÃnicos sugerem que a L-ornitina-L-aspartato pode ter uma influência favorável na encefalopatia hepática em virtude do seu efeito na redução da amônia, e melhora dos sintomas e achados laboratoriais.

CONCLUSIONS: Exclusion of cardiac disease is of crucial importance. On the other hand non-cardiac chest pain could be related to gastrointestinal, muscular and respiratory causes and/or psychological disturbances. Treatment aims to attack mechanism generator in order to relieve or to eliminate symptoms. Drugs are the cornerstone of treatment, exception to achalasia patients because those have better response to dilation of the esophagus or surgery, and to those who need intensive pyschological therapy. The most important drugs used are proton pump inhibitors and triciclic antidepressants, the latter, to modulate central si...
