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.

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.

Assessment of baseline characteristics and risk factors among Emergency Department patients presenting with recent onset atrial fibrillation: a retrospective cohort study.

BACKGROUND: The Cardioversion of Atrial Fibrillation in Emergency (CAFE) study was an observational, retrospective, multicenter study focusing on patients with recent onset atrial fibrillation (AF) seen in six different Emergency Departments (ED) of Rome, Italy. AIM: The aim of this study was to present the baseline characteristics and risk factors of the patients enrolled to the CAFE study. MATERIALS AND METHODS: We retrospectively reviewed 3085 eligible patients diagnosed with recent onset AF in any of the EDs between January 2008 and December 2009. Inclusion criteria required documented ICD-9 primary discharge/admission diagnosis of AF in the ED and stable hemodynamic conditions at presentation (systolic blood pressure > 90 mmHg). Exclusion criteria were permanent AF or an ongoing acute coronary syndrome. RESULTS: Median age was 71 years (interquartile ranges, 62-78 years) and 50.8% were men. Palpitations was the most common symptom at ED presentation and was present in 73.5% of the study subjects. Hypertension was the most prevalent comorbidity, affecting 59.3% of the patients evaluated, and the presence of previous episode(s) of AF was also common (52.3%). Regarding home treatment, the drugs most prescribed were antiplatelets (31.2%) and diuretics (25.2%). A CHADS2 score of 0 was found in 814 patients (26.4%), while a CHADS2 score of 1 was reported in 1114 patients (36.1%). Finally, a CHADS2 score ≥ 2 was reported in 1157 patients (37.5%). CONCLUSIONS: The present study represents an important snapshot of demographics, comorbidities, risk factors and anticoagulation management about patients with recent onset AF. Disparities were noted in anticoagulation management, suggesting that this is still a main problem among patients with AF.

A critical review of the efficacy and safety in the use of low-molecular-weight heparin in acute ST-elevation myocardial infarction: a Bayesan approach.

BACKGROUND: ST segment elevation myocardial infarction (STEMI) is an important risk factor of death worldwide. Significant clinical research has been done to assess ideal reperfusion strategies in the setting of STEMI, including the role of the antithrombin agents: unfractionated heparin (UFH) and low molecular weight heparin (LMWH). Given the evidence that LMWH may be safer than UFH in the treatment of other thrombotic disorders, its role in the management of STEMI needs to be more defined. OBJECTIVE: To assess the safety and efficacy of LMWH compared to UFH and/or placebo for the treatment of STEMI. MATERIALS AND METHODS: The Cochrane Library, MedLine and EMABASE databases were searched for randomized controlled trials pertinent to the study objective. Selection criteria included all randomized controlled trials comparing LMWH to either UFH or placebo in the treatment of STEMI through December 2010. Two Authors performed the search independently.After identifying appropriate studies, a random effect model and Bayesian sensitivity analysis were used to combine results from original trials and assess the consistency of results. RESULTS: We identified 13 studies that met the described selection criteria; 8 comparing LMWH to UFH and 5 to placebo in STEMI patients. The combined Odd's ratio was 0.79 with a 95% confidence interval of 0.67-0.94 for all studies and 0.74 (0.54-1.02) for those comparing LMWH to UFH only. A trend toward more frequent hemorrhagic events was identified in the LMWH group (Odd's ratio 1.40) which did not meet statistical significance (95% confidence interval 0.80-2.47). Sensitivity analysis demonstrated clinical benefits of 6% and 12.5% with probabilities of 99% and 95% respectively. CONCLUSION: Compared to placebo or UFH, LMWH is effective as a first line treatment of STEMI patient with no significant increase in major hemorrhagic events.

Effect of beta-glucan, inositol and digestive enzymes in GI symptoms of patients with IBS.

BACKGROUND: Irritable bowel syndrome (IBS) is a very common functional gastrointestinal (GI). Diagnosis of IBS is based on the fulfilment of the Rome III criteria. Common GI symptoms are lower abdominal pain, bloating and disturbed defecation, such as urgent diarrhoea and/or episodes of chronic constipation. Many agents have been employed in the management of IBS, although only few have been demonstrated to show a relevant efficacy. AIM: To evaluate the effectiveness of the administration of a mixture of beta-glucan, inositol and digestive enzymes (Biointo) in improving GI symptoms in patients affected by IBS. PATIENTS AND METHODS: 50 IBS patients (20 males, 30 females; mean age 51 +/- 19) were treated with Biointo (group A) while another group consisting of 40 IBS patients (15 males, 25 females; mean age 50 +/- 18) did not receive any therapy (group B). RESULTS: Biointol administration improved significantly bloating, flatulence and abdominal pain, with a slight increasing of urgency for bowel movements. On the contrary, Biointol did not show any significant effect on the other IBS symptoms. CONCLUSIONS: Currently, only few agents used in the management of IBS have been proven to be effective. Biointol administration has shown to improve some IBS symptoms, such as bloating, flatulence and abdominal pain, all connected to the presence of gas inside the intestinal lumen.

Paracetamol-codeine compared to ketorolac for pain control in the Emergency Department.

OBJECTIVE: Paracetamol /codeine has shown a strong analgesic activity in several studies conducted among different kind of subjects, including those with trauma. Nevertheless, its efficacy in patients accessing the Emergency Department (ED) for different kind of pain has never been tested. PATIENTS AND METHODS: This is a cross-sectional, observational, prospective, cohort study. Inclusion criteria were patients > 18 year old presenting to the ED for localized traumatic or inflammatory pain involving only extremities. Numeric scale (NRS) was recorded thirty minutes and two hours after the administration of the analgesic therapy, consisting of 15 mg of ketorolac or 1000 mg/60 mg of paracetamol/ codeine, both orally. RESULTS: Two-hundred patients were consecutively enrolled; 87 were treated with paracetamol/codeine and 113 with ketorolac. The combination paracetamol/codeine resulted to be not inferior to ketorolac in non-traumatic pain group and trauma group (p = 0.635 and p = 0.482, respectively). Compared to ketorolac, the combination paracetamol/codeine exerted a significantly higher analgesic activity in patients with fractures and muscular pain (p = 0.044) and was more effective in acute pain (p = 0.002), with a significant effect two hours after the administration (p = 0.029). CONCLUSIONS: Paracetamol/codeine is equivalent to ketorolac in non-traumatic pain and post-traumatic pain, but is superior in acute pain and in patients with fractures and muscular pain. Those results play in favor of the use of the combination paracetamol/codeine in patients accessing the ED for non-traumatic or traumatic pain of the extremities.
