The binding affinity between vitamin B12 (VitB12) and bovine serum albumin (BSA) has been investigated in aqueous solution at pH=7.4, employing UV-vis absorption and steady-state, synchronous and three-dimensional fluorescence spectra techniques. Representative effects noted for BSA intrinsic fluorescence resulting from the interactions with VitB12 confirm the formation of π-π stacked non-covalent and non-fluorescent complexes in the system VitB12-BSA. All the determined parameters, the binding, fluorescence quenching and bimolecular quenching rate constants (of the order of 10(4)Lmol(-1), 10(3)Lmol(-1) and 10(11)Lmol(-1)s(-1), respectively), as well as Förster resonance energy transfer parameters validate the mechanism of static quenching...

In the past few years, research on chronicization of headache has focussed primarily on migraine, even though there are other types of primary headache that over time can turn into chronic forms. Only a minority of migraine sufferers will develop a chronic condition, with attacks that are likely to vary in their clinical features. As a result, in chronic migraine the specific diagnostic criteria for this headache type do not always exhibit the typical features of migraine. Among the factors that play a major role in favouring chronicization are a high frequency of migraine attacks since the beginning, overuse of symptomatic medication and onset of depression or arterial hypertension...

Since the nineteenth century several clinical features have been observed in common between migraine and epilepsy (such as episodic attacks, triggering factors, presence of aura, frequent familiarity), but only in recent years researchers have really engaged in finding a common pathogenic mechanism. From studies of disease incidence, we understand how either migraine among patients with epilepsy or epilepsy among migraine patients are more frequent than in the general population. This association may result from a direct causality, by the same environmental risk factors and/or by a common genetic susceptibility...

There is a debate in literature about the therapeutic usefulness of oral devices in patients suffering from Medication Overuse Headache (MOH) or in patients suffering from Persistent Idiopathic Facial Pain (PIFP). From the case histories of 3356 patients, referred to us with a diagnosis of chronic craniofacial pain for assessment of the eventual application of an occlusal device to correct an impaired neuromuscular relationship between the mandible and the maxilla, we selected, following the criteria of the International Classification of Headache Disorders (ICHD-3beta), two groups of patients suffering from MOH and PIFP...

The use of Onabotulinumtoxin A as treatment for different neurological conditions is more common in the last decades; its application has been consolidated on the basis of significant clinical results. The clinical experiences with Onabotulinumtoxin A for chronic migraine are on the increase in Italy: at the moment, clinical results are encouraging and enforce the application of the toxin for chronic migraine, according to the results of the PREEMPT studies. The possibility for the patients to be treated with a second cycle of therapy after the first year of treatment is under discussion, in particular for patients who obtained significant clinical benefit from the first period of treatment...

Chronic migraine (CM) is a disabling condition arising from a complex mixture of interconnected biological, psychological and social factors, and is often associated with medication overuse (MO). Mindfulness is emerging as a helpful treatment for pain, and one study showed that the longitudinal 12 months' course of CM-MO patients that attended mindfulness-based treatment alone was similar to that of patients receiving medical prophylaxis alone; in this study, we describe the course of biomarkers of inflammation...

The objective was to assess the cost of Medication Overuse Headache (MOH) at the time-point of withdrawal treatment. We implemented a protocol in which both direct and indirect cost were directly gathered from patients and referred to the previous three months. Direct costs were calculated by medications for acute treatment and prophylaxis, diagnostic procedures, visits, complementary treatments, informal care. Indirect costs were referred to missed workdays and workdays with reduced productivity: we asked patients to refer their salaries and to rate the overall level of performance in days worked with reduced productivity, and we calculated indirect costs on this basis...

The objective was to characterize frequent relapsers (FR)-i.e. those requiring two or more withdrawals in a 3-year period-in a sample of 188 patients with chronic migraine with medication overuse (CM-MO). We tested differences between FR and non-FR for age, gender, employment status, days with headache, headache severity, type of overused medication, BDI-II, WHODAS 2.0 and MSQ. 30.8% of participants were FR: they were more frequently treated as inpatients and living alone, had a lower education, higher disability and lower QoL, higher frequency and intensity of headaches, and higher depression scores...

Migraine is a disabling neurovascular syndrome which affects 12-15% of the global population and it represents the third cause in years lived with disability in both males and females aged 15-49 years. Among migraineurs, the symptomatic drug abuse may be a risk factor in the development of medication overuse headache (MOH). Detecting cases of MOH is not straightforward; community pharmacists may, therefore, be in a strategic position to identify individuals who self-medicate, particularly with respect to prevent the development of MOH...

Since chronic migraine is difficult to treat and often associated with medication overuse, non-invasive neurostimulation approaches are worth investigating. Transcutaneous supraorbital neurostimulation using the Cefaly(®) device is promising as a non-invasive preventive treatment for episodic migraine, but no data are available for chronic migraine. Our aim was to perform a preliminary evaluation of the efficacy of the Cefaly(®) device for the prophylaxis of chronic migraine with or without medication overuse...

Inappropriate use of antibiotics is contributing to the increasing rates of antimicrobial resistance. Several Danish guidelines on antibiotic prescribing for acute respiratory tract infections in general practice have been issued to promote rational prescribing of antibiotics, however it is unclear if these recommendations are followed. We aimed to characterise the pattern of antibiotic prescriptions for patients diagnosed with acute respiratory tract infections, by means of electronic prescriptions, labeled with clinical indications, from Danish general practice...

BACKGROUND: The Canadian Computed Tomography (CT) Head Rule, a clinical decision rule designed to safely reduce imaging in minor head injury, has been rigorously validated and implemented, and yet expected decreases in CT were unsuccessful. Recent work has identified empathic care as a key component in decreasing CT overuse. Health information technology can hinder the clinician-patient relationship. Patient-centered decision tools to support the clinician-patient relationship are needed to promote evidence-based decisions...

Nowadays, whole-body cryotherapy is a medical physical treatment widely used in sports medicine. Recovery from injuries (e.g., trauma, overuse) and after-season recovery are the main purposes for application. However, the most recent studies confirmed the anti-inflammatory, anti-analgesic, and anti-oxidant effects of this therapy by highlighting the underlying physiological responses. In addition to its therapeutic effects, whole-body cryotherapy has been demonstrated to be a preventive strategy against the deleterious effects of exercise-induced inflammation and soreness...

Despite the popularity of the sport, few studies have investigated community-level football injury patterns. This study examines football injuries treated at emergency medical facilities using data from three Swedish counties. An open-cohort design was used based on residents aged 0-59 years in three Swedish counties (pop. 645 520). Data were collected from emergency medical facilities in the study counties between 1 January 2007 and 31 December 2010. Injury frequencies and proportions for age groups stratified by sex were calculated with 95% confidence intervals (95% CIs) and displayed per diagnostic group and body location...

The key pathophysiological feature of chronic obstructive pulmonary disease (COPD) is an abnormal inflammatory bronchial reaction after inhalation of toxic substances. The priority is the avoidance of such toxic inhalations, but the use of anti-inflammatory drugs also seems appropriate, especially corticosteroids that are the sole anti-inflammatory drug available for this purpose in France. The risks associated with the prolonged use of these parenteral drugs are well known. Inhalation is therefore the optimal route, but inhaled drugs may also lead to adverse consequences...

The global overuse of antibiotics has led to the emergence of drug-resistant pathogenic bacteria. Bacteria can combat β-lactams by expressing β-lactamases. Inhibitors of one class of β-lactamase, the serine-β-lactamases, are used clinically to prevent degradation of β-lactam antibiotics. However, a second class of β-lactamase, the metallo-β-lactamases (MBLs), function by a different mechanism to serine-β-lactamases and no inhibitors of MBLs have progressed to be used in the clinic. Bacteria that express MBLs are an increasingly important threat to human health...

BACKGROUND: Investigating beliefs about medicines has been of interest over the past years, with studies aiming to better understand theoretical reasons behind development of such beliefs. OBJECTIVE: This study aimed to produce a culturally and contextually appropriate version of the Beliefs about Medicines Questionnaire (BMQ) in the Maltese language and to assess its psychometric properties. METHODS: Medication beliefs were evaluated using the BMQ which is divided into two sections: BMQ-General (sub-scales: Overuse and Harm, 4 items per sub-scale) and BMQ-Specific (sub-scales: Necessity and Concerns, 5 items per sub-scale)...
