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.

Obesity, bariatric surgery and periodontal disease: a literature update

Obesity is linked to other systemic diseases, such as diabetes mellitus, dyslipidemia, and arterial hypertension. These comorbidities increase the risk of developing cardiovascular disease risk. Adipose tissue is a true endocrine organ and releases various pro-inflammatory cytokines. Periodontal disease (PD) is a chronic inflammatory disorder of the gingiva and bone support (periodontal tissues) that surrounds the teeth. The relationship between obesity and an increased risk of developing PD is already known in the literature. Many studies correlated the cardiometabolic risk with periodontal disease. Bariatric surgery is a way to reduce the adipose tissue in obese patients, that meet specific criteria. It has been observed that this type of surgery usually reduces both the systemic inflammation and the cardiometabolic risk. Some authors have hypothesized that, as a result, the progression of periodontal disease is also reduced. Five articles are analyzed in this systematic review. In these papers, the periodontal health before and after the bariatric surgery was compared. However, the conclusion of the previous studies demonstrated a scarce literature and did not confirm the reduction of periodontal disease after bariatric surgery, but a reduction of cardiometabolic risk. Therefore, periodontal disease in no way influences the reduction of cardiovascular risk after bariatric surgery.

FTO rs9939609 influence on adipose tissue localization in the Italian population

OBJECTIVE

Among the genes involved in obesity, the Fat mass and obesity-associated gene (FTO) is certainly one of the most known and the relation between FTO rs9939609 and BMI is highly discussed; nevertheless, data about its influence on body composition are limited.

MATERIALS AND METHODS

We carried out a study on a sample of 1066 Italian subjects, whose body composition and FTO rs9939609 were analyzed.

RESULTS

We found significant relations between FTO with arm (p=0.01), abdomen (p=0.00), and trunk circumferences (p=0.00), BMI (p=0.01), FM% (p=0.00), and android FM% (p=0.01), whereas no relations were found between FTO and both gynoid fat and lean mass.

CONCLUSIONS

To conclude, the relation between FTO and BMI is confirmed and is related specifically with android FM%. These results indicated that FTO rs9939609 may be a genetic etiological factor for obesity. Indeed, the specificity for the android FM% would indicate FTO as an etiological factor in the development of cardiovascular diseases.

The role of IL-6 gene polymorphisms in the risk of lipedema

OBJECTIVE

Lipedema is a disorder of adipose tissue characterized by abnormal subcutaneous fat deposition, leading to swelling and enlargement of the lower limbs and trunk. The aim of this study was to evaluate the lipedema phenotype by investigating the role of polymorphisms related to IL-6 (rs1800795) gene in people with diagnosis of lipedema. The second aim was to identify indicators of body composition, useful for a differential analysis between subjects with lipedema and the control group.

PATIENTS AND METHODS

Two groups are involved in the study, 45 women with lipedema (LIPPY) and 50 women randomly chosen from the population as Control (CTRL). Clinical and demographical variables recorded include weight, height, body mass index (BMI) and circumference measurements. Body composition (Fat mass, FM; lean mass, LM) was assessed by Dual-energy X-ray Absorptiometry (DXA). The genetic tests for IL-6 (rs18oo795) gene were performed for both groups, using a saliva sample.

RESULTS

The study of the relationship between the IL-6 (rs1800795) gene polymorphism, the anthropometric values and the body composition indices has provided the following significant results: subjects with diagnosis of lipedema present statistically significant increased values with regard to weight, BMI, waist, abdomen and hip circumferences, arms, legs and whole FM (% and kg), gynoid FM (kg), legs LM (kg) and ASMMI. Moreover, the value of the waist hip ratio was found to be decreased.

CONCLUSIONS

For the first time, we suggested that IL-6 gene polymorphism could characterize subjects with lipedema respect to Normal Weight Obese and obese subjects. The intra-group comparisons (LIPPY carriers vs. LIPPY non-carriers and CTRL carriers vs. CTRL non-carriers) showed no statistically significant values. In contrast, the inter-group comparisons (LIPPY non-carriers vs. CTRL non-carriers and LIPPY carriers vs. CTRL carriers) resulted statistically significant. We have identified other indices, such as leg index, trunk index, abdominal index, total index, that could be promising clinical tools for diagnosis of the lipedema phenotype and for predicting the evolution of the disease.

Magnesium sulphate in the Emergency Department: an old, new friend

With our study, we searched the medical literature to find magnesium (Mg) correlation with Emergency situations or its use in Emergency Medicine. Our aim is to fill the gap that we find in our daily routine between Mg studies on its role in Emergency and the real conception that doctors have of it in medical practice. We searched the literature for terms as magnesium or magnesium sulphate, magnesium in emergency, eclampsia, arrhythmias, acute asthma exacerbation, magnesium, and pediatric population. After a thorough research, we divided our discoveries into chapters to sort out a large amount often discordant articles.

Developing and cross-validation of new equations to estimate fat mass in Italian population

OBJECTIVE

Obesity is a global burden that involves more than 500 million people. The objective of this work is to develop and cross-validate the new sex-specific equations to estimate fat mass, based on anthropometric parameters and to compare with other equations.

PATIENTS AND METHODS

We evaluated 38762 subjects by dual-energy X-ray absorptiometry (DXA) and enrolled 1434 women and 640 men, aged between 18 and 65 years. Then, we randomized 480 men and 1080 women in developing set and 160 men and 354 women in the cross-validation set. Statistical analysis as multiple regression and Bland-Altman methods were performed.

RESULTS

Sex-specific equations were created based on developing set. Then, based on the cross-validating set, these equations were validated and were observed to agree with fat mass by DXA, better than other equations, such as BAI and RFM.

CONCLUSIONS

These new sex-specific equations represent an easy tool, since they require only two circumferences, to be used in clinical practice. In the next future, these equations could be validated and refine on specific Italian sub-populations, divided by gender and age, such as the military.

Lean body mass: reference values for Italian population between 18 to 88 years old

OBJECTIVE

Body's lean mass compartment is a strong predictor of morbidity and mortality risk in various clinical conditions. This paper proposes a simple and easily applied reference table for lean body mass (LBM) and lean body mass index (LBMI) for the Italian population.

PATIENTS AND METHODS

Retrospective analysis of a database containing anthropometric and DXA body composition measurements obtained from a cross-sectional study conducted between 2002 and 2009 with Italian individuals. Parametric and nonparametric tests were performed using R 3.1.1 and SPSS 22.0 software packages.

RESULTS

The 3712 study participants, 37.3% men and 62.7% women, aging from 18 to 88 years. Individuals with normal weight, overweight and obesity were evenly distributed in the sample. LBM and LBMI measures were significantly higher in males. In both genders, there was a significant and progressive decline in these measures associated with aging. Significant differences in LBMI between genders were found in all age groups except for individuals over 75 years.

CONCLUSIONS

Based on the participants LBM profile, a reference table for LBM values was proposed. This reference will be useful to detect changes in the LBM compartment of individuals from the South Central Region of Italy, supporting health professionals during the process of diagnosing sarcopenia.

Role of phase angle in the evaluation of effect of an immuno-enhanced formula in post-surgical cancer patients: a randomized clinical trial

OBJECTIVE

Neoplastic disease is frequently associated with poor nutritional status or severe malnutrition. Diet and nutritional intervention are becoming increasingly important for prognosis and quality of life in cancer patients. Accessible and repeatable tools for assessing nutritional status with body composition techniques seems to be fundamental. The aim of this study was to evaluate the effects of immunonutrition on body composition parameters, inflammatory response and nutritional status in patients at stage III of head and neck squamous carcinoma (HNSCC).

PATIENTS AND METHODS

In our work, 50 malnourished subjects with HNSCC staging III were recruited and treated with oral diet (OD) or enteral nutrition (EN). Patient under EN followed, for the first three days, enteral standard nutrition (ESN) and then enteral immunonutrition (EIN). Nutrition state was evaluated on days 0, 3, and 8 through body composition and biochemical analyses.

RESULTS

After 8 days, the EIN treatment showed a significant improvement in phase angle, pre-albumin, retinol binding protein and transferrin compared to the OD treatment.

CONCLUSIONS

Our results showed that immunonutrition treatment improves the nutritional status of neoplastic patients, supporting chemotherapy. The phase angle is not only a predictor of cancer survival, but has also proved to be useful in the surveillance of nutritional status improvement as well as biochemical indices.

Efficacy and safety of dronedarone in patients with amiodarone-induced hyperthyroidism: a clinical study

OBJECTIVE

The aim of the study was to examine the safety and efficacy of dronedarone in patients with a history of atrial fibrillation and amiodarone-induced hyperthyroidism.

PATIENTS AND METHODS

We conducted a prospective study to evaluate the use of amiodarone and dronedarone in 124 patients with a history of paroxysmal atrial fibrillation who had no additional structural heart disease. All patients received amiodarone 200 mg qd. Out of 124 patients, 56 (45%) switched to dronedarone 400 mg bid due to amiodarone-induced hyperthyroidism and the remaining 68 patients (55%), with normal thyroid function, continued to receive amiodarone. The follow-up period was 12 months, and the patients were regularly monitored.

RESULTS

The primary outcome after 6 months dronedarone and amiodarone group was 56 and 68, including 38 (68%) and 54 (79.4%) (Odds ratio [OR] = 1.17, 95% confidence interval [95% CI] = 0.68-2.02) patients with sinus rhythm (SR) and 18 (32.14%) and 14 (28.6%) (odds ratio [OR] = 0.64, confidence interval [95% CI] = 0.29-1.40) patients with atrial fibrillation (AF). The secondary outcome after 12 months showed significant difference in thyroid function in the dronedarone group. Out of 46 patients, 24 (56.18%) patients reduced hyperthyroidism compared to the amiodarone group; out of 68, 6 (8.9%) patients were observed to have hyperthyroidism. At 12 months, there were 24 (43%) and 22 (62%) (odds ratio [OR] = 0.75, confidence interval [95% CI] = 0.38-1.49) patients with SR, and 32 (57%) and 26 (38%) (odds ratio [OR] = 0.67, confidence interval [95% CI] = 0.36-1.25) patients with AF.

CONCLUSIONS

In our study, dronedarone appears to be a good therapeutic option in the treatment of atrial fibrillation in patients with amiodarone-induced hyperthyroidism. However, long-term studies are needed to estimate the efficacy and toxicity of both drugs.

Effects of new probiotic mouthwash in patients with diabetes mellitus and cardiovascular diseases

OBJECTIVE

To evaluate the impact of a new formulation of probiotic mouthwash (PM), using Biocult strong® dissolved in neutral mouthwash.

PATIENTS AND METHODS

Forty-two patients with cardiovascular disease (CVD) or type 1 and type 2 diabetes were enrolled. Plaque Control Record (PCR) and Bleeding on Probing (BOP) were assessed at baseline and after two weeks of PM or positive control treatment in intervention group (IG) and control group (CG). Food intake was estimated by 3-day diet record.

RESULTS

BOP was significantly reduced in all treatments and samples, except for IG in CVD sample (p=0.15). PCR decreased significantly in all treatments and samples (p<0.01). No significance was obtained for BOP and IP in the time x group interaction. Food intake was not significantly different between IG and CG in all samples. Nutrients such as fats and simple carbohydrates were correlated with BOP in patients who received positive control, rather than PM, indicating a lack of food influence on BOP and PCR in IG.

CONCLUSIONS

PM treatment was effective in relation to the reduction of PCR and BOP. Probiotics represent a good, but additional, tool for prophylaxis, because they cannot completely substitute the classic oral hygiene methods. Moreover, one week of treatment was not sufficient to draw firm conclusions about the efficacy of the treatment itself.

Efficacy and safety of very-low-calorie ketogenic diet: a double blind randomized crossover study

OBJECTIVE

To verify safety respect to weight loss, cardiometabolic diseases of short-term Very low-calorie ketogenic diets (VLCKDs, <800 kcal day-1).

PATIENTS AND METHODS

Randomized cross-over trial with placebo. The study had no. 2 dietary treatment (DT), conducted in two arms: (1) VLCKD1 in which 50% of protein intake is replaced with synthetic amino acids; (2) VLCKD2 with placebo. The VLCKDs (<800 kcal day-1) were different in term of protein content and quality each arm lasted three weeks (wks). Between the two arms a 3-wks washout period was performed to avoid additive effects on DT to follow. At the baseline, at start and end of each arm, all the subjects were evaluated for their health and nutritional status, by anthropometric analysis, body composition (Dual X-ray Absorptiometry (DXA), Bioimpedentiometry, biochemical evaluation, and Peroxisome Proliferator-Activated Receptor γ (PPAR) γ expression by transcriptomic analysis.

RESULTS

After VLCKD1 were reduced: Body Mass Index (BMI) (Δ%=-11.1%, p=0.00), Total Body Water (TBW) (p<0.05); Android Fat Percentage (AFP) (Δ%=-1.8%, p=0.02); Android Fat Mass (AFM) (Δ%=-12.7%, p=0.00); Gynoid Fat Mass (GFM) (Δ%=-6.3%, p=0.01); Intermuscular Adipose Tissue (IMAT) (Δ%= -11.1%, p=0.00); Homeostasis Model Assessment of Insulin Re-sistance (HOMA-IR) (Δ%=-62.1%, p=0.01). After VLCKD1 a significant increase of uricemia, cre-atinine and aspartate aminotransferase (AST) (respectively Δ%=35%, p=0.01; Δ%=5.9%, p=0.02; Δ%=25.5%, p=0.03). After VLCKD2 were reduced: BMI (Δ%=-11.2%, p=0.00); AFM (Δ%=-14.3%, p=0.00); GFM (Δ%=-6.3%, p=0.00); Appendicular Skeletal Muscle Mass Index (ASMMI) (Δ%=-17.5%, p=0.00); HOMA-IR (Δ%=-59,4%, p=0.02). After VLCKD2, uricemia (Δ%=63.1%, p=0.03), and Vitamin D levels (Δ%=25.7%, p=0.02) were increased. No significant changes of car-diovascular disease (CVD) indexes were observed after DTs. No significant changes of PPARγ lev-el in any DTs.

CONCLUSIONS

21-days VLCKDs not impair nutritional state; not cause negative changes in global measurements of nutritional state including sarcopenia, bone mineral content, hepatic, renal and lipid profile.

Post-prandial effects of hazelnut-enriched high fat meal on LDL oxidative status, oxidative and inflammatory gene expression of healthy subjects: a randomized trial

OBJECTIVE

Postprandial oxidative stress is characterized by an increased susceptibility of the organism towards oxidative damage after consumption of a meal rich in lipids and/or carbohydrates. Micronutrients modulate the immune system and exert a protective action by reducing low-density lipoproteins oxidation (ox-LDL) via induction of antioxidant enzymes.

SUBJECTS AND METHODS

The clinical study was a randomized and cross-over trial, conducted through the CONSORT flowchart. We evaluated the gene expression of 103 genes related to oxidative stress (HOSp) and human inflammasome pathways (HIp), and ox-LDL level at fasting and after 40 g raw "Tonda Gentile delle Langhe" hazelnut consumption, in association with a McDonald's® Meal (McDM) in 22 healthy human volunteers.

RESULTS

Ox-LDL levels significantly increased comparing no dietary treatment (NDT) vs. McDM, and decreased comparing McDM vs. McDM + H (p<0.05). Percentage of significant genes expressed after each dietary treatment were the follows: (A) NDT vs. McDM: 3.88% HIp and 17.48% HOSp; (B) NDT vs. McDM + H: 17.48% HIp and 23.30% HOSp; (C) McDM vs. McDM + H: 17.48% HIp and 33.98% HOSp.

CONCLUSIONS

Hazelnut consumption reduced post prandial risk factors of atherosclerosis, such as ox-LDL, and the expression of inflammation and oxidative stress related genes. Chronic studies on larger population are necessary before definitive conclusions.

Endocarditis sustained by Streptococcus viridans with normal levels of procalcitonin: an unexpected finding

OBJECTIVE

Procalcytonin is a useful marker of bacterial infections. Several studies have reported elevated serum levels of PCT in patients with infective endocarditis (IE) and/or other infections sustained by cocci. We report a rare case of IE attributed to Streptococcus viridans in whom levels of PCT were normal.

CASE REPORT

A 67 years-old male was admitted to the Emergency Department for a 25-day history of recurring night fever. Upon admission, patient underwent blood test, including PCT, showing normal levels, except for a slight increased creatinine concentration (1.6 mg/dl). CBC showed WBC levels of 10.24 x 10^9/l with neutrophil concentration of 8.64 x 10^9/l. Three blood culture were performed, and all of them were positive for Streptococcus viridans (S. oralis). Dosage of PCT was then repeated two times within the next 2 days after the admission, with negative results. An echocardiogram was performed, showing a lesion of the left anterior aortic leaflet. This finding was confirmed by a transoesophageal echocardiogram. The patient was then treated with G penicillin (6 million of Units quid) for 3 weeks; during the course of antibiotic therapy fever disappeared and blood cultures become negative.

CONCLUSIONS

In the literature, there are just few data about the association between PCT levels and endocarditis and sepsis but there are not etiological differentiations particularly for those sustained by Streptococcus viridans. Only one study suggests that a Streptococcus viridans' infection could reduce PCT accuracy in diagnosis oh endocarditis. So, our observation although come from a single case, could merits, further investigation.

The probiotics in dentistry: a narrative review

The total number of microbes that colonize the human body is far greater than the number of cells that make it up. In recent years, it has been shown that bacteria play an essential role in the body; in fact, they are essential for the maturation of the intestine, the development and control of the immune system, the development of the brain, the metabolism of macronutrients, the synthesis of vitamins, and the energy balance. Bacteria play an essential role in defense of their territory against the entry of other bacteria that may be pathogenic to health. Metchnikoff, about a century ago, invented probiotics, assuming that the use of certain bacteria could be beneficial to maintaining health. Bacteria colonize our body from birth and breastfeeding, using the bacterial flora of the mother by accessing newborns through the mouth. Antibiotic therapies in pregnancy or cesarean section prevent this flow of probiotics to infants and open the way for very important diseases, such as diabetes and obesity. The alterations of oral bacterial flora are responsible for numerous diseases of the oral cavity and the idea of the use of probiotics is leading the way to new therapeutic perspectives.

Effects of very-low-calorie diet on body composition, metabolic state, and genes expression: a randomized double-blind placebo-controlled trial

OBJECTIVE

Very low-calorie diets (VLCDs, < 800 kcal day-1) and Ketogenic diet (KD) are generally used as part of integrated intervention, medical monitoring and a program of lifestyle modification, to improve a multitude of clinical states. The effect of three different very low calories KD (VLCKD), with (VLCKD1) or without (VLCKD2,3) synthetic amino acid replacement of the 50% protein intake, were analyzed after weight loss.

PATIENTS AND METHODS

The clinical study used a cross-over randomized double-blind placebo-controlled trial. Obese subjects, who were eligible for the study, were randomly (R) divided into three groups: one intervention group (IG) and two control groups (CG1 and CG2). We comprehensively analyzed body composition, serum metabolites, superoxide dismutase (SOD1), nuclear factor kappa-light-chain-enhancer of activated B cells (NfKB), Chemokine (C-C Motif) Ligand 2 (CCL2) gene expression.

RESULTS

After VLDKDs a significant decreased in BMI was observed. TBF (kg) significantly decrease after VLCKD1 and VLCKD3. After VLCKD2, a reduction of waist circumference (p = 0.02), FM L2-L5 (p < 0.05) was observed. After VLCKD1 reduction of IMAT (p = 0.00), LDL-C (p = 0.00) and HDL-C (p = 0.00) were observed. No significant changes of GH, ESR, and fibrinogen were highlighted. CRP (p = 0.02) reduced significantly after VLCKD3. Significant modulation of SOD1 expression (p = 0.009), CRP and decrease of glucose levels (p = 0.03) were obtained after VLCKD3.

CONCLUSIONS

This is the first study that analyzes comprehensively body composition, metabolic profile, and inflammation and oxidative stress genes expression after VLCKD. Our results show the efficacy of VLCKD with synthetic aminoacidic protein replacement, for the reduction of cardiovascular risk, without the development of sarcopenia and activation of inflammatory and oxidative processes.

Safety and efficacy of low doses of diclofenac on acute pain in the emergency setting

Diclofenac is the most widely prescribed non-steroidal anti-inflammatory drug worldwide. Data collected during the last 10 years reported a dose-duration dependent increasing of cardiovascular risk associated with the use of diclofenac, supporting the evidence of a close association with the degree of COX-2 inhibition achieved in vivo. Nevertheless, the amplitude of cardiovascular risk associated with the administration of diclofenac at low doses and for the short-term duration is still poorly defined. Indeed, data did not show a clear and strong increasing of the risk for daily doses of 75 and of 50 mg. Concerning duration, while the identification of a safe temporal window is less defined, some studies reported an absence or a very low risk when the exposure is shorter than 30 days. Today, new low-dosage diclofenac formulations are available, allowing to reduce the systemic exposure, the degree of COX-2 inhibition and possibly the risk of occurrence of cardiovascular events. This is the reason why those new formulations may represent the ideal drug for the management of pain in the emergency setting.

Very-low-calorie ketogenic diet with aminoacid supplement versus very low restricted-calorie diet for preserving muscle mass during weight loss: a pilot double-blind study

OBJECTIVE

Obesity plays a relevant pathophysiological role in the development of health problems, arising as result of complex interaction of genetic, nutritional and metabolic factors. We conducted a dietary intervention case-control randomized trial, to compare the effectiveness on body composition of two nutritional protocols: a very-low-carbohydrate ketogenic diet (VLCKD), integrated by an aminoacid supplement with whey protein, and very low restricted-calorie diet (VLCD).

PATIENTS AND METHODS

The clinical study was conducted with a randomized case-control in which twenty-five healthy subjects gave informed consent to participate in the interventional study and were evaluated for their health and nutritional status, by anthropometric, and body composition evaluation.

RESULTS

The results of this pilot study show that a diet low in carbohydrates, associated with a decreased caloric intake, is effective in weight loss. After VLCKD, versus VLCD, no significant differences in body lean of the trunk, body lean distribution (android and gynoid), total body lean were observed (p > 0.05). After VLCKD, no increasing of sarcopenia frequency, according ASSMI, was observed.

DISCUSSION

Many studies have shown the effectiveness of the ketogenic diet on weight loss; even if not know how to work effectively, as some researchers believe that the weight loss is due to reduced calorie intake, satiety could also be induced by the effect of the proteins, rather than the low-carbohydrates.

CONCLUSIONS

Our pilot study showed that a VLCKD was highly effective in terms of body weight reduction without to induce lean body mass loss, preventing the risk of sarcopenia. Further clinical trials are needed on a larger population and long-term body weight maintenance and risk factors management effects of VLCKD. There is no doubt, however, that a proper dietary approach would impact significantly on the reduction of public expenditure costs, in view of prospective data on increasing the percentage of obese people in our nation.

A bedside test for Clostridium Difficile infection: an Emergency Department use. Preliminary results

OBJECTIVE

Clostridium Difficile (CD) infection is a severe cause of diarrhea in patients with prolonged hospitalization and/or previously treated with antibiotics. CD's A and B toxins are responsible for either diarrhea or septical status as well as other complications including toxic megacolon. Toxins isolation, usually performed by a central microbiological laboratory (CML), is mandatory for the final diagnosis of the disease. The clinical suspect of CD infection (CDI) results in the isolation of the patients, until the fecal test does not exclude the disease. Positive patients need to maintain isolation and start a specific antibiotic therapy. The aim of this study was to verify the sensitivity and specificity of a rapid test for the diagnosis of CDI.

PATIENTS AND METHODS

We enrolled 20 (13F/7M, mean age 70 ± 12 yrs) consecutive pts who accessed the Emergency Department (ED) with diarrhea and a clinical suspect of CDI. An immune-enzymatic bedside test (Beta Dignostici, Messina, Italy) for the detection of GDH, toxin A and B of CD was used. The results of this test were then compared to the CML one's, on the same patient.

RESULTS

6 patients resulted positive to the bedside test compared to 7 of CML test (86% of concordance). In this patient, the bedside test showed a strong positivity for GDH without signs of toxin, meanwhile the CML test revealed the toxins. Possibly, the lower toxins concentration in this patient was responsible for such discordance. Both tests showed a full concordance for negative patients. Another interesting finding is that the bedside test provides results in only 5 minutes, compared to several hours (even 48) of CML test.

CONCLUSIONS

The bedside test is a rapid and affordable tool for rapid diagnosis of CD infection especially in a ED where the positivity of the test affects either hospitalization or treatment.

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.

Recurrent use of the Emergency Department in patients with anxiety disorder

OBJECTIVE

Panic disorder is characterized by the spontaneous and unexpected occurrence of panic attacks. During panic attacks, patients (pts) refer to the Emergency Department (ED). The diagnostic work-up for any panic attack is expensive since symptoms at presentation mimic other diseases such acute coronary syndrome or neurological emergencies. The aim of the present study was to describe a 10 years cohort of pts diagnosed with panic disorder in the ED in terms of ED visit recurrence.

METHODS

Case-control study, in a tertiary care, involving pts presenting to the ED and diagnosed with panic attack according to the International Classification of Diseases 9nt Revision (ICD-9). From January 2001 to Dec 2009 were extracted from the electronic clinical database 469 pts and were divided into "recurrent ED visit" (multiple ED access for panic attack) (N=361) and "no recurrent ED visit" (only one ED access for panic attack in 9 years) (N=108).

RESULTS

At univariate analysis cases and controls differed for male prevalence (p < 0.01), neurological symptoms at presentation (p = 0.02) and history of other psychiatry disorder (p < 0.01). In multivariate analysis independent predictors were male gender, age under 40 year old, palpitations at presentations, 1 or more cardiovascular risk factors and previous other psychiatry conditions.

CONCLUSIONS

Male under 40 years old with palpitations or cardiovascular risk and other psychiatric diseases, have a higher recurrence of panic attacks. General psychiatric evaluation and treatment with benzodiazepine in ED is not useful to prevent recurrences. Identifying those patients at high risk of panic attack and ED visit recurrence might be useful to establish ad-hoc interventions, improve patients' morbidity and save precious resources.

Acetaminophen plus codeine compared to ketorolac in polytrauma patients

INTRODUCTION

The management of pain in polytrauma patients is mandatory. While non-steroidal anti-inflammatory drugs (NSAIDs) represent the most used drugs in polytrauma patients, their use may be associated with an increased risk of haemorrhage. Opioids may represent a valid alternative to NSAIDs either alone or in combination with acetaminophen. Whether their efficacy is comparable to that produced by NSAIDs in polytrauma patients has never been studied.

PATIENTS AND METHODS

60 polytrauma patients were enrolled for this study. 30 patients were treated with acetaminophen 1000 mg plus codeine 60 mg tid for 24 hours (Group A), while the remaining 30 with ketorolac 10 mg qid for 24 hours (Group B). Pain intensity has been evaluated using an analogical visual scale (VAS) ranging from 0 (no pain) to 10 (very severe pain). The level of pain was valuated at enrolment (TO) as well as after 2 (T2), 12 (T12) and 24 (T24) hours from the starting of the analgesic therapy. Results obtained by the group A were compared with those reported by the group B.

RESULTS

T0: Group A mean score was 6.4 +/- 1.5 compared with 6.6 +/- 1.5 of Group B (p= ns); T2: Group A mean score was 3.4 +/- 2.8, compared with 3.5 +/- 2.4 of group B (p = ns); T12: Group A mean score was 3.4 +/- 3.4, compared with 3.5 +/- 3 of Gorup B (p = ns); T24: Group A mean score was 2.9 +/- 1.5, compared to 3.0 +/- 1.6 of Group B (p = ns). All those drugs determined a significant reduction of pain intensity during the course of therapy.

CONCLUSIONS

Acetaminophen plus codeine is effective in pain control in polytrauma patients at least in our series. It may represent a valid alternative to NSAIDs, especially in patients with a documented haemorrhage or with a high hemorrhagic risk.

High dosage rifaximin for the treatment of small intestinal bacterial overgrowth

BACKGROUND

Rifaximin is a broad spectrum non-absorbable antibiotic used for treatment of small intestinal bacterial overgrowth. Doses of 1200 mg/day showed a decontamination rate of 60% with low side-effects incidence.

AIMS

To assess efficacy, safety and tolerability of rifaximin 1600 mg with respect to 1200 mg/day for small intestinal bacterial overgrowth treatment.

METHODS

Eighty consecutive small intestinal bacterial overgrowth patients were enrolled. Diagnosis of small intestinal bacterial overgrowth based the clinical history and positivity to H(2)/CH(4) glucose breath test. Patients were randomized in two 7-day treatment groups: rifaximin 1600 mg (group 1); rifaximin 1200 mg (group 2). Glucose breath test was reassessed 1 month after. Compliance and side-effect incidence were also evaluated.

RESULTS

One drop-out was observed in group 1 and two in group 2. Glucose breath test normalization rate was significantly higher in group 1 with respect to group 2 both in intention-to-treat (80% vs. 58%; P < 0.05) and per protocol analysis (82% vs. 61%; P < 0.05). No significant differences in patient compliance and incidence of side effects were found between groups.

CONCLUSIONS

Rifaximin 1600 mg/day showed a significantly higher efficacy for small intestinal bacterial overgrowth treatment with respect to 1200 mg with similar compliance and side-effect profile.

Catholic university experience with molecular adsorbent recycling system in patients with severe liver failure

BACKGROUND AND AIM

Molecular adsorbent recycling system (MARS) treatment is able to remove both hydrosoluble and small- and medium-sized lipophilic toxins. MARS plays an important role in modifying liver failure complications, such as hepatorenal syndrome and hepatic encephalopathy. We sought to evaluate the clinical efficacy and safety of a MARS device in a consecutive series of hepatic failure patients.

MATERIALS

Twenty patients with acute liver failure, transplantation failure, or acute on chronic liver failure fulfilled the inclusion criteria of total bilirubin > or =10 mg/dL and at least one of the following: hepatic encephalopathy (HE) > or =II grade, hepatorenal syndrome (HRS) for chronic patients or total bilirubin > or =5 mg/dL and HE > or =I grade for acute patients.

RESULTS

MARS was able to reduce cholestatic parameters and improve neurologic status and renal function parameters in all treated patients. We also observed an improvement in the 3-month survival rate compared to the expected outcome in patients with MELD scores between 20 and 29, as well as 30 and 39.

CONCLUSIONS

Based on these results, we confirm the safety and clinical efficacy of MARS treatment, with the best results in patients with MELD score of 20 to 29. Further studies are necessary to confirm whether this treatment is able to modify patient outcomes and prognosis.
