Management of acute dyarrhea: current and future trends.

Acute diarrhea is a very common symptom, which may recognize different causes and is basically the expression of an altered homeostasis of the bowel, which overcame current classifications. When approaching patients with acute diarrhea, we should firstly check body temperature and vital parameters and secondly provide a general medical examination mainly focused on the abdomen, in order to exclude surgical causes of diarrhea, such as acute appendicitis, diverticulitis, intestinal occlusion and others. Another important aspect is the assessment of the level of hydration in order to provide the right amount of fluids. There is no current indication for the administration of loperamide in infectious diarrhea, but there is a strong rationale for new class of drugs, which may be defined as "mucous regenerators", such as gelatin tannate. Further studies are needed on this matter in order to test the effect of gelatin tannate in adult patients with acute diarrhea.

Safety and efficacy of the combination acetaminophen-codeine in the treatment of pain of different origin.

BACKGROUND: Pain is the most common reason people see doctors in developed Countries and a very common cause of access in Emergency Department (ED). The combination acetaminophen/codeine represents the standard medication in the second step of the WHO analgesic scale and codeine is one of the most commonly used opioid analgesic for a variety of pain conditions. However, many aspects related to safety and efficacy are still undefined. AIM: To summarize and review the results of the most relevant studies on the efficacy and safety profile of acetaminophen/codeine combination in the treatment of pain of different origin. MATERIALS AND METHODS: We performed a literature search to identify and evaluate all relevant english-language randomized controlled trials (RCTs), meta-analyses and reviews about the codeine plus paracetamol combination in the treatment of pain from any source. RESULTS: Acetaminophen/codeine combination is effective in the treatment of moderate to severe pain in all setting analyzed in this study, which include headache, postoperative, osteoarticular and post-traumatic. The best results in terms of safety and efficacy have been obtained in postoperative pain. Efficacy of acetaminophen/codeine combination is not inferior to NSAIDs. CONCLUSIONS: Acetaminophen/codeine combination is effective in the treatment of pain, through a synergistic action of the two molecules, and is not inferior to NSAIDs. Side effects of acetaminophen/codeine are usually minor, differently from NSAIDs, which may induce some potentially life threatening conditions.
