Role of first aid in the management of acute alcohol intoxication: a narrative review.

OBJECTIVE: Acute alcohol intoxication is actually a common admission cause in the Emergency Department and represents an increasing public health burden, in particular among adolescents. It involves possible and significant illness and injury, which can quickly get worse and may need to be managed in the emergency room. MATERIALS AND METHODS: We conducted a narrative review of the literature regarding the effectiveness of first aid role of the Emergency Department setting. RESULTS: This review included eighteen studies about alcohol intoxication management in the Emergency Department; most of all highlights the emerging phenomenon in Europe and around the world of acute alcohol intoxication management in first aid. The treatment of acute alcohol intoxication depends on general clinical conditions of the patient, vital signs, hemodynamic stability, cognitive state, alcohol-related complications, which are closely related to the blood alcohol concentration. At the same time, symptoms could be extremely variable due to individual differences in alcohol metabolism. In case of mild-moderate intoxication (blood alcohol concentration < 1 g/L), no drugs are necessary. In case of severe intoxication (blood alcohol concentration > 1 g/L), it is necessary to support with intravenous fluids, treat hypoglycemia, hypotension, hypothermia and electrolyte imbalance, administer complex B and C vitamins and accelerate alcohol elimination from blood with metadoxine. Unlike adults, adolescents are more exposed to the toxic effect of alcohol (because of their immature hepatic alcohol dehydrogenase activity), and then, acute alcohol-related complications are more frequent and dangerous in young people than in adult population. In many cases, patients affected by acute alcohol intoxication referring to an Emergency Department have mild-moderate transitory symptoms that do not require the use of drugs; they can benefit from a clinical observation, with a clinical course often completed within 24 hours with a favorable outcome. Clinical observation with vital signs control is necessary also to evaluate the possible development of the alcohol withdrawal syndrome (that involves a specific treatment) and to evaluate also possible pathological complications of the organism, above all acute liver damage. CONCLUSIONS: Patients affected by acute alcohol intoxication are the best candidates to apply the rules of the Temporary Observation Unit in the Emergency Department, because of a clinical course often completed within 24 hours, a favorable outcome and without the need for hospitalization. In many cases, hospitalization could be not necessary, but the patient affected by Alcohol Use Disorder must be referred to an Alcohol Addiction Unit for the follow-up, to reduce the risk of alcohol relapse and complications related to alcohol abuse, and financial costs of hospitalization.

Microbes and Alzheimer' disease: lessons from H. pylori and GUT microbiota.

OBJECTIVE: the role of microbes and chronic inflammation in the pathogenesis of Alzheimer' disease (AD) has been postulated by many authors. On the other hand, several studies have reported the main role of H. pylori infection and/or GUT microbiota alteration in promoting chronic inflammation, thus possibly influencing both occurrence and evolution of AD. In this article, we analyze the most important and recent studies performed on this field both on humans and animals and provide possible pathogenic explanations. RESULTS: all main and most recent animal, human, epidemiological and in-silico studies, showed a role of H. pylori and/or dysbiosis in AD, mostly through the promotion of systemic chronic inflammation and/or by triggering molecular mimicry mechanisms. In particular, H. pylori infection seems to be related to a poorer cognitive performance. CONCLUSIONS: Indeed, bacteria have been shown to affect neurodegeneration by promoting inflammation, inducing molecular mimicry mechanisms and accumulation of Aß into the brain. These findings open the way for H. pylori eradicating trials and/or GUT microbiota remodulating strategies. Therefore, further studies are now needed in order to test whether antibiotics, pre and/or probiotics may exert a beneficial effect in the prevention of AD.

State and trait anxiety and depression in patients affected by gastrointestinal diseases: psychometric evaluation of 1641 patients referred to an internal medicine outpatient setting.

OBJECTIVES: To evaluate state and trait form of anxiety and current depression in patients affected by gastrointestinal diseases. METHODS: We studied 1641 outpatients with gastrointestinal disorders, consecutively referred to our Internal Medicine outpatients from 1997 to 2005. State and trait anxiety were assessed by the State and Trait Anxiety Inventory. Current depression was assessed by the Zung self-rating depression scale. RESULTS: Among patients, 1379 (84.1%) showed state anxiety, 1098 (67%) showed trait anxiety and 442 (27%) showed current depression. The number of gastrointestinal diseases was directly correlated to state anxiety (p < 0.001) and trait anxiety (p = 0.04). Females showed higher levels of anxiety and depression than males (p < 0.001). State anxiety was related to food allergies (p < 0.001), small intestinal bacterial overgrowth (SIBO) (p = 0.001), Hp infection (p = 0.01) and ulcerative colitis in active phase (p = 0.03). Trait anxiety was related to irritable bowel syndrome (IBS) (p < 0.001), Helicobacter pylori (Hp) infection (p = 0.001), food allergies (p = 0.001) and SIBO (p = 0.001). Current depression was related to IBS (p < 0.001) and coeliac disease (p = 0.01), SIBO (p = 0.02). A predicted probability of 0.77 +/- 0.16 to have state anxiety, of 0.66 +/- 0.12 to have trait anxiety and of 0.39 +/- 0.14 to have depression was found in these patients. CONCLUSIONS: Most of the patients who seek medical consultation for gastrointestinal problems show an associated affective disorder. These patients should be managed by a team including gastroenterologists, psychologists and/or psychiatrists, or by a gastroenterologist having expertise in the treatment of psychological disorders.

Nicotinamide and tetracycline therapy of bullous pemphigoid.

BACKGROUND AND DESIGN: The combination of nicotinamide and tetracycline has been anecdotally reported to be effective in the treatment of bullous pemphigoid. We conducted a randomized, open-labeled trial comparing the combination of 500 mg of nicotinamide, three times daily, and 500 mg of tetracycline four times daily, with prednisone therapy in 20 patients with bullous pemphigoid. The study was divided between an 8-week acute phase with fixed drug dosages and a 10-month follow-up phase in which study medications were tapered based on patient response. RESULTS: Eighteen of 20 patients enrolled in the study were treated, two patients were unavailable for follow-up. Twelve patients were treated with the combination of nicotinamide and tetracycline and six patients were treated with prednisone. There were five complete responses, five partial responses, one nonresponder, and one patient with disease progression in the nicotinamide and tetracycline group compared with one complete response and five partial responses in the prednisone group. There were no statistically significant differences in response parameters between the two groups. All five patients in the nicotinamide and tetracycline group receiving long-term follow-up remained disease free during medication tapering, while three patients in the prednisone group had repeated disease flare-ups with steroid tapering. Adverse effects in the nicotinamide and tetracycline group included gastrointestinal upset (two patients) and transient renal failure (one patient). In the prednisone group, there was one occurrence each of hypertension, erosive gastritis, multiple decubitus ulcers, osteomyelitis, deep venous thrombosis, and death related to sepsis. Two patients required insulin therapy for hyperglycemia. CONCLUSIONS: The combination of nicotinamide and tetracycline appears to be a useful alternative to systemic steroids in the treatment of bullous pemphigoid.

Effects of a therapeutic camping program on addiction recovery. The Algonquin Haymarket Relapse Prevention Program.

A group of 13 men and women in substance abuse treatment participated in a 3-day residential program experience based on integrated principles from adventure therapy, therapeutic camping, and relapse prevention. The experimental group is compared to a group of 18 men and women who received the usual and customary relapse prevention program. Both groups completed pre- and postintervention questionnaires. There were no differences in drinking-related locus of control, stress, or problem-solving between groups at postinterview, but there were significant improvements in autonomic arousal, frequency of negative thoughts, and alcohol craving. Participants in both groups were interviewed 10 months after the 3-day intervention. Considering individuals who were unreachable as relapsed, the 10-month follow-up relapse rate was 31% for the experimental group and 58% for the comparison group. These results add to the limited body of research supporting outdoor adventure and therapeutic camping experiences integrated with traditional relapse prevention activities as an adjunct to substance abuse treatment.
